Welding the ears
The order of work here will look like this (for convenience, let’s imagine that the hinges need to be welded onto an ordinary metal gate).
First, thick metal plates are welded to the hinges - they are called plates or ears. This is done like this:
- two plates are laid horizontally so that there is a gap of about 2-3 millimeters between them;
- a loop is placed in the gap;
- These same plates are welded to the loop with a continuous seam - one to the top of the loop, the second to the bottom.
The presence of lugs greatly facilitates further work and increases the service life of the gate. They do not allow the fabric to “tear” even with the heavy mass of the entire structure.
Installation of teardrop hinges
Let's consider the option of how to weld teardrop-shaped hinges to racks and gates of any design - corrugated, forged, solid, etc. It should be taken into account that the hinges are installed strictly vertically or parallel to the racks, even a slight misalignment will lead to difficulty opening or closing the doors, as a result - premature failure of the support bearing.
It will be most convenient to weld the parts on a horizontal surface - before installation, when all the elements can be laid out on a flat area. They are carefully aligned and also centered in the same plane according to the level. The required gap required to open the doors is set, the same distance from the top and bottom is marked along the entire perimeter. It is better to weld the canopy to a pre-marked place, with the tail of the lower part of the drop turned towards the post, and the tail of the upper part towards the gate. First, teardrop-shaped canopies are grabbed by welding, then turning the stand, making sure that it rotates easily. Having achieved a positive result, they begin full welding.
Loop welding technology
Before we talk about how to weld hinges on gates, it is worth taking a closer look at the conditions necessary for their normal operation.
Even if the load is calculated correctly, the hinges may not be able to cope with it if their position deviates even slightly from the vertical. They will quickly fail. And the second point: there should be a small gap of 1-2 mm between the hinge body and the support post so that the metal parts of the post and the mating part of the canopy do not touch or rub against each other. The same gap should be left on the side of the sash.
Required number of loops
The overall dimensions of the welded hinges, as well as their number, are selected in accordance with the weight of the gate. The heavier it is, the more there should be. Or they themselves should be more powerful.
The recommended quantity is shown in the table:
Loop brand and height, mm | 610-4 (100) | 610-5 (125) | 613-4 (100) | 613-5 (125) | 500-4 (100) | 500-5 (125) | 401-4 (100) | 700-4 (100) | 700-5 (125) |

The nuances of installation on supports of different sections
The supporting posts on which the sashes are hung can be round, square or, less commonly, rectangular in cross-section. There is a difference between how to properly weld gate hinges to round posts or supports made of profile pipes.
If the profile pipe has smooth edges without bends or distortions, then it will be easy to cope with the task of how to properly weld gate hinges to square posts. They are installed on the outer plane of the support.

In the case of a round support, you must first decide in which direction the doors will open. Then they find the most protruding line (the middle of the pillar relative to the opening) and step back from it a few millimeters outward - in the direction of plowing. 5-6 mm is enough for the wicket or gate leaf to move smoothly and without jerking around the axis of the canopy. Since it is more difficult to weld hinges on gates to round posts than to square ones, here you need to be especially careful and attentive, maintaining the same indentation size for all hinges.
Installation and welding work
Experienced welders recommend first welding the canopies to the sashes, laying them on a flat horizontal surface. A half in the form of a hollow cylinder is welded to them, and a mating part with a pin (pin up) is subsequently welded to the supports. They retreat approximately 15 cm from the top and bottom edges.

Then the sash with welded canopies is installed in the opening on stands that provide the required distance to the ground, and is rigidly fixed with clamps, pliers and other devices. They do this so that it stands strictly vertically, and there is a gap of 5 mm or so between it and the support. To do this, use a laser level or a plumb line, and spacers of the required thickness are inserted between the elements.
Other craftsmen prefer to first install the gate, and then weld the hinges to both it and the post. There is no big difference, everyone does what is convenient for them.
Another option is to make the upper and lower ribs of the frame whole when making the sashes and cut them after hanging them on the hinges. Source sqezo.ru
Now let’s talk about how to properly weld canopies on gates. The sequence of work looks like this:
- 1.5-2.5 mm thick wire is wrapped and twisted around the loops at the top and bottom to form a gap between it and the welding plane. You can place matches or other objects of suitable thickness, but they fall out, move or break, which is very inconvenient;
- The places where the canopies are attached are marked on the supports and an even long block or profile pipe is applied to them. Fix it level, ensuring a vertical position.
Selection and installation
The length of the loops and their number are selected depending on the size and weight of the gate. The longer the boom, the more mounting holes it has, preventing the canvas from sagging under its weight.
As for weight:
Hanging the gate is easy to do with your own hands. To do this, the long part is first screwed to the canvas.
Then the gate is installed in place and fixed using wedges, clamps or other devices in the designed position.
After which the second part of the canopy is attached to the pole or box.
Advice. If over time the canvas does sag, it will not be difficult to adjust the operation of the gate. It is enough to unscrew the screws, level it and tighten them again.

See how it looks in this video:
loops with twisted wire are pressed against the block and the post and are also fixed in a vertical position;
the loops are welded to the supports at 2-3 points;
in the same way, they grab the second (upper) part of the hinges to the frame or leaf of the doors;
when the tacks have hardened, the gate is checked for opening - it should swing open 180 degrees without jamming or warping;
if everything is in order, the sashes are closed again, fixed and the hinges are welded onto the finishing surface with a continuous seam from the bottom up;
cooled seams are cleaned of scale with a hammer and sanded with a grinder to give a more aesthetic appearance

Do not open the gate until the welds have completely cooled and gained strength.
Metal gates can also be hung on other awnings, which are secured with screws or nuts. But the welded method is more reliable and durable, especially if you know how to properly weld hinges on gates and strictly follow all the requirements regarding their installation technology.
Loop welding technology
To properly weld the hinges, it is necessary to align the door leaf strictly according to the level. It is best to use a laser level, since a regular bubble tool may cause errors. The gate is fixed using stands and wedges in a stationary position. This is how they will stand even after welding loops on them. After this, loops with plates are applied to them, which should be located on the same axis. It is recommended to mark the locations of the plates.
Gate installation methods
Loop awnings can be welded to a gate or wicket in two ways:
- First, the fastenings are welded to the gate leaf, and then to the support pillars. It is recommended to start work by attaching the bottom hinge. The most difficult part is to make a vertical weld between the plate and the base metal. You should perform several tacks and then make sure that the gate leaf is working properly. Tacks are performed in the following sequence:
- Above.
- From below.
- In the center.
- In the center of the first half of the seam.
- In the center of the second half of the seam.
This way both loops are caught. If after this the sash closes and swings open normally, a continuous seam is created. The movement of the electrode when creating a vertical seam should be directed from bottom to top. Next, the horizontal seams are welded. After welding the lower hinge, an additional check is made of the axial fastening of the upper fastening, since movement of the blade may have occurred during the welding process.
- How to weld hinges in a different sequence? For many, this method will seem the most acceptable. The lower parts of the loops with plates are first welded to the support posts. Then the top parts with balls are inserted into them. After this, the door leaf is set in place. The plaits are pressed tightly against the canvas, after which they are scalded.
When the installation of the gate is completed, the welds are cleaned of scale and ground with a grinder. It is prohibited to open the gate until the welds have completely cooled.
Process technology
Installing plates
Many inexperienced welders have certain doubts about the possibility of welding cylindrical hinges to a flat surface. There is no doubt that this procedure with round loops is much easier to perform than with square and hexagonal ones.
In order to properly weld round hinges, you need to take care of installing the plates - they are welded to the hinges themselves using a welding machine. It is necessary to do this with an even seam. By welding the plates to the hinges, a convenient platform is created for installing the hinges on the gate itself. These irreplaceable elements are selected in accordance with the weight of the gate and the strength of the material from which the plates are made.
Reinforcing loops with plaits
Some craftsmen weld hinges without using plates. This option is also possible, but thanks to their use the fastening is more reliable.
Installing gates
Before welding the hinges on the gate, the gate leaves must be correctly positioned in the opening of the garage or fence. The complexity of the procedure lies in the fact that the gate should be placed in the opening before the hinges are welded, that is, virtually by eye. To position the gate as accurately as possible, you need to use a building level and a lot of patience. Adjustment of the gate position should be carried out as many times as necessary until the gates are in a level position. Only after precise placement can welding be carried out.

We weld the hinges to the gate
Now let's figure out how to properly weld the hinges on the gate. Despite the apparent complexity of this procedure, it is quite possible to perform it with the proper skill and patience. Welding hinges on garage doors is carried out in several sequential steps listed below:
- Lubricate garage hinges with welded plates with grease to ensure their smooth movement after installation. Also prepare thin linings for the hinges - their thickness should not exceed 5 mm. They are necessary primarily for round hinges.
- Make the correct markings of the fabric for the loops. So, it is necessary to mark indentations from the edges of 25-30 cm. The markings are applied with a construction pencil.
Prepared plates
- Weld the hinges to the door leaf. To do this, first weld the bayonet parts of the hinges, at first only slightly grabbing them by welding, then weld the metal from the bottom to the top, while ensuring the most even seam.
- After welding the first seam on all hinges, you need to use a level (it is better to use a construction level for these purposes) to check the correct opening and closing of the gate. If no defects are found, you can continue.
Iron loop welded to the gate
- After the installation of hinges on the gate by welding is completed, you need to carefully process all welds with a grinding machine. The last stage is painting the gates and hinges in any color you like. That's all!
As you can see, attaching the gate hinges yourself is not such a difficult task, impossible to do at home. It is enough to have the necessary equipment at hand and strictly follow the recommendations for action specified in this manual.
If you are installing garage door hinges, weld them in such a way that the doors open outward. Otherwise, big problems will arise after the snowfall.
How to weld the hinges yourself
Welding hinges is not an easy task, especially for beginners. But, if you have patience and desire, you can cope with such work even in the absence of serious experience.
To work you will need the following tools:
- metal tape measure;
- level;
- hammer;
- welding machine;
- Sander;
- special mask;
- gloves for welding work.
Rules:
- When working with a welding machine, you must strictly follow safety rules. A protective mask and gloves must be used.
- In accordance with fire safety standards, welding is prohibited near flammable liquids and objects.
- When hinges are welded to the gate, they need to be lightly “grabbed” by welding.
- Since the hinges are welded to the door leaf, when drawing up the drawing, you need to take into account that the distance from the lower edge of the leaf to the lower hinges, as well as from the upper edge to the upper hinges, must be at least 20 cm. On the wings, the place where the hinges are attached is marked with a pencil.
- Fasteners should be thoroughly lubricated with grease. This measure will protect them from cracking when exposed to high temperatures.
- It is believed that if a match is placed along the edges of the hinges, the door will not jam during welding.
- You need to wedge the doors so that when closed they are level. To level the sashes, use a building level.
Stages of work:
- First, the hinge part located at the bottom is welded. The gate hinge must be fixed in the direction from bottom to top. During the welding process, the electrode should be moved horizontally and with extremely smooth movements.
- After the first seam, the gate leaves must be wedged to check their operation. The hinges are fully welded only after the quality of opening and closing the doors has been checked.
- After welding is completed, the frame must be removed from its hinges, generously lubricated with grease and returned to its place.
- All welding seams must be processed with a grinding machine, and then covered with metal paint.
- Properly welded hinges provide the structure with quick, delay-free opening. You can also close such gates easily - with one movement of your hand.
Additional features:
- During welding, only serviceable equipment should be used. A faulty device must be repaired by a qualified technician.
- The work of welding hinges to the gate cannot be carried out alone.
- It is prohibited to weld on metal whose surface has traces of fresh paint.
- If there are traces of gasoline, fats, or oil on the protective overalls or gloves, they must be changed. The presence of flammable liquids on clothing is considered unacceptable.
- It is prohibited to weld vessels under pressure.
- Do not place rags soaked in oil on the cylinders, as such carelessness always leads to a fire.
Selection of loops and their number
Please note that welded hinges most often have a round cross-section and, when assembled, will resemble a cylinder. But their cross-section is teardrop-shaped, with a point along the walls
The configuration will not affect the performance characteristics of the product in any way, and it is also selected solely for ease of installation - for some it is more convenient to attach some, and for others the rest. But in fact, it is not enough to know exactly how to weld the hinges to the gate - first you need to calculate the load on them and decide on the number. This is not so difficult to do if you know about the weight of the sashes.
Hinges that do not have plates can withstand a maximum of 4 quintals depending on their length and diameter, as well as the thickness of the metal. And the loops with plates that take on all the loads that are designed for heavier weights - they can withstand up to 6 centners. Knowing the design type of load on the hinges, as well as the structural weight, you can determine their required number. Naturally, less than two pieces per sash will not work. And if the gate is heavy, then the number of canopies should be 3-4. The additional loop needs to be installed slightly lower than the top one, which will bear the main load. By the way, you can even strengthen simple hinges yourself by welding to them plates cut from thick metal of the required size. The weld seam should be continuous.
Welding
Next, you need to prepare the hinges - clean them of rust and fatty deposits, lubricate them with grease or other similar compound. This will prevent so-called hinge sintering when you start welding.
Now you need to use the welding machine: first, the fittings are welded to the gate leaf, and only then to the support pillars. In this case, it is necessary to constantly monitor the quality of the resulting seams.
When all welding work is completed, it is advisable to process the new seams with a grinder.
You can weld hinges on a gate, garage door and on a metal door according to the same scheme as described above.
However, it should be noted that the craftsman usually has the opportunity to weld the fittings onto the door at the moment when it is in a horizontal position on a flat area, which greatly facilitates the process.
This does not work out with gates: the support pillars, as a rule, are installed much earlier than the actual installation of the curtains begins.
Installation options depending on the wicket material
According to criteria such as the total weight of the structure and the building material from which it is made, it is customary to distinguish two main methods for installing hinges to the main gate posts:
- Use of electric welding.
- Self-tapping screws.
The first installation method is appropriate for heavy (mainly metal) structures, the second - for light gates (made of wood, concrete, wicker).
Below we will take a closer look at the technology for installing lightweight gates using self-tapping screws.
The method of installing a wicket door on hinges using self-tapping screws is similar in technical content to installing interior doors, only the fastening elements in this case are wicket hinges. The latter are connected to the façade of the structure, which ensures significant durability and also makes the gate more aesthetically attractive. This fastening method is applicable for wooden, stone, and sometimes light metal units.
Fastening with self-tapping screws
The mechanism of work is as follows:
- The wicket hinge is attached to the facade of the structure using wood screws. Their number is two or three.
- Next, the gate should be placed on support posts to mark the place where the second segments of the mounting structures will be fixed.
- The pillars are installed in pre-prepared holes, their lower ends are pre-wrapped with roofing felt. Structures must be vertically fixed. If the gate weighs little, you can do without the additional concreting procedure. The unit is simply attached using self-tapping screws to the support post.
If the master is dealing with heavy metal gates, he cannot do without a welding machine. The technology for welding loops will be discussed below.

Step-by-step instructions for installing corrugated gates with your own hands are discussed in this article.
Basic truths
The process of installing hinges can be considered using the example of a metal gate. In order for it to properly perform its main functions, a number of conditions must be met when welding hinges:
- Provide a gap between the support post and the gate frame, which should be 3-5 mm.
- Provide a gap of several millimeters between the hinge and the gate frame by welding plates - metal plates of the required thickness - to the hinge. In total, for each loop you need two strips, the length of each of them is 2 mm less than the length of half.
- The optimal distance from the edge of the gate to the loop is 15-20 cm. If you need a middle loop, then it is located exactly in the middle between the outer loops.
First, the lower part of the fastener (with the pin) is welded to the post, then the upper part (with the groove) is welded to the sash.
A properly assembled structure should have the following parts:
- a loop;
- plate; wicket frame;
- support pillar;
- lower part (with pin);
- upper part (with groove).
All loops must be coaxial, that is, their centers must be on the same straight line. The alignment requirement is extremely important. It is on its compliance that it depends on how evenly the weight of the gate will be distributed on the fastenings and, accordingly, how long they will last.
To work, the master will need:
- welding machine;
- metal plate for making plates;
- Bulgarian;
- hammer;
- plumb line;
- oil for lubricating hinges;
- protective equipment - mask, gloves, overalls.
At the preparatory stage, you should mark the gate frame and sash, determining the places where the hinges will be welded. Clean them from dust, dirt, and rust. To do this, you can use a wire brush and solvents. Next, a similar treatment is performed on the surface of the hinges, and lubricant is applied to their inner part.
The traditional welding method involves the installation of plates at this stage, for which it is recommended:
- Take 2 identical plates of the required thickness and length. Place them so that there is a gap of 2-3 mm between them.
- Place the bottom part of the loop on them.
- Weld the loop to one of the plates (in this case, to the right one).
- Do the same for the top of the hinge and weld it to the left plate.
- Then you need to install the shutters in the working position and fix them.
- The plates with the lower part of each hinge are spot welded to the post, then the upper hinge elements are inserted into the lower parts and spot welded to the sash. After checking the alignment of the hinges and the operation of the gate, final welding is carried out along the contour of the plates.
Installation recommendations
For square-section posts, it is recommended to always use plates, maintaining a gap of 3–5 mm between the edge of the gate and the support. There are several ways to weld hinges to round posts:
- without the use of mounting plates;
- with a plate only on the sash;
- with a narrow spacer on the side of the post and a full plate on the gate.
When using spacers, it is possible to increase the gap between the hinge and the support, and the spacer can be placed at an angle. This design is more forgiving of welding flaws, but it looks sloppy.
Gates are made in a variety of sizes and shapes and from various building materials. Today, the most popular gates are products made from wood and profiled metal sheets. Such designs are not very massive products of medium weight or even light. In many ways, the durability of these sashes depends on correctly selected and properly secured hinges.
Simple homemade hinges for gates
Types of loops
Taking into account the GOST classification, gate curtains are divided into the following categories:
- Cylindrical.
- Through.
- Hidden.
- Articulated.
- Decorative forged.
- Teardrop-shaped.
- Adjustable.
Cylindrical (regular and reinforced)
Mechanisms with a cylindrical configuration have a support bearing. They are used on small gates with permissible loads of up to 400 kg. Models with reinforcement have special plates that help distribute the load evenly over the surface of the post or fittings. The modification is in demand for products made from profile pipes. They are usually welded to garage doors using an ordinary welding machine or secured with a screw connection.
Depending on the side of placement, reinforced models are available on the right and left. The standard diameter of the product is 50 mm, and the permissible load is 600 kg.
The permissible load on hinges with a support bearing is 400 kg, on reinforced ones - 500 kg.
End-to-end
If it is not possible to secure the curtains by welding or screwing, a through option can be used as an alternative. To install the mechanism, you will need to drill mounting columns along the length of the frame and place part of the retainer in them. The final fastening of the product with your own hands is done with nuts of the appropriate size. Such fasteners can handle loads of up to 200 kg.
The permissible load on through hinges is 200 kg.
Hidden
Unlike previous varieties, hidden loops are well camouflaged, because they are installed in a sash frame and welded to the frame and the transverse surface of the pillars from the inside. It is quite difficult to detect the placement of such fittings, which increases its resistance to burglary. Such loops are used at those facilities where valuable property is stored. The products are distinguished by their durability because they are isolated from harmful influences.
Installation diagram for hidden hinges.
Articulated
This group includes reinforced and semi-hinged elements. In the first type, the axial rod is attached to 2 halves of the card. This provides a cylindrical joint that rotates easily. The half-hinged option involves placing the axis rod in only one half of the card. The design is not particularly reliable.
Decorative forged
They are considered an outdated type of gate hinge, which does not lose popularity despite the availability of more effective solutions. Most often, forged curtains are found on wooden fences and are used as a decorative element. At the same time, there are mechanisms on sale that are not inferior in strength to modern analogues.
Decorative loops.
teardrop-shaped
Teardrop-shaped fasteners are equally effective on metal and wood structures. Their popularity is due to their increased strength and resistance to mechanical loads. In addition, the fittings look original.
Adjustable
This option is suitable for any garages, warehouses and other similar facilities. Due to the design features, the mechanisms allow you to adjust the position of the sashes in height. Such hinges are in demand when there is a possibility of deformation of the support posts. They can handle loads up to 200 kg.
Adjustable hinges, permissible load - 200 kg.
Wooden gate hinges
You can buy your favorite wooden gate inexpensively at any construction market.
An example of the design of forged hinges for a wooden gate
If you have a gate, all that remains is to select hinges that match it in terms of characteristics and dimensions. Correctly chosen fastening will provide the sash with an ideal “fit” and full-fledged long-term operation. For a small wooden gate, the most suitable way to fix the hinges is to install the door with self-tapping screws.
Installation of hinges with self-tapping screws
In principle, this method of attaching hinges is similar to installing interior doors. However, to install a wicket, the components must be wicket or gate components. When choosing this type of fixation, the hinges are attached to the end of the gate, providing the structure with additional stability and improving its external performance.
Stages of installing a wooden gate:
- Using wood screws, the wicket hinge should be attached to the facade of the sash in the marked places. For greater reliability, it is advisable to use at least 3 hinges for 1 gate.
Attaching hinges to the gate with self-tapping screws
An example of installed posts for a wooden gate
For support pillars, a hole should be made at least 120 cm deep. At the bottom of the hole there must be a compacted sand cushion (15 cm in height). The pillars can be backfilled or concreted. This method of installing them will save the structure from shrinkage, which is fraught with transfer of loops.
Types of hinges and their installation
Loops can be divided into several types:
Cylindrical with bearing for support.
Used for mounting standard gates that are not too heavy in weight. It is not recommended to load such systems with a load of more than 0.4 tons since this is their maximum permissible weight. This information should be asked before purchasing because it may vary for each model and brand.
They look like a cylinder that is divided into 2 parts. One of them has an end in the form of a rod, which, during installation, enters the second part with an empty core and a ball at the bottom. This bearing makes the mechanism smoother during movement if too much load is applied. On one of its sides there is a special place for installing a plug, which can be removed.
Cylindrical hinges for gatesSource vorota-goroda.ru
Reinforced structures in shape.
They cope with loads of up to 0.6 tons and differ from the first ones only in the fastening plate, which makes it possible to correctly distribute the mass over the surface. Such a mechanism can be installed using welding or, as in interroom passages, with self-tapping screws, and the opening of doors when using such a hinge can be in both directions.
This fastener is made of durable steel, which increases the maximum permissible load weight and durability of the product. Before purchasing, it is recommended to check the bearing for special markings.
Through.
Used when welding or other fasteners cannot be used. To install them, the gate support is drilled through and secured with nuts on the other side. Such loops can only withstand small weights, their maximum is 200 kg. They are made right-handed or left-handed, and can also be equipped with canopies.
Hidden.
They have a special design that can be easily hidden if the gate is closed. They are attached to the side of the post, which acts as a support, and to the inside of the frame. The advantage of this design is that these hinges can only be dismantled with special tools.
Hidden mechanismSource www.travelnews24.ru
Three-section overhead (magnetic).
They are made as hinged or semi-hinged, and can be used for gates with a large weight. There are three types: decorative, standard and removable.
There is also a difference in the shape of the loops:
- Cylindrical. They are tightly fixed on the surface of the gate, as well as smooth and easy rotation of the mechanism.
- Square. When installing, you need to step back a little from the frame. The fixation is more reliable than the previous ones.
- Hexagonal. Universal hinges that can be fixed both cylindrical and square.
- Teardrop-shaped. They are used for various structures and have high strength and resistance to loosening.
When choosing gate awnings, it is important to ensure that they match the material. If the hinge doesn't fit metal or wood, it won't last long. . Drop-shaped loopsSource news2.ru

Selection of corrugated sheets
Corrugated sheets differ among themselves in thickness, degree of strength and rib height.
- “C” is a lightweight and durable galvanized wall sheet with low thickness and rib height. The most common choice;
- “NS” is a denser profiled sheet with a higher rib height, but also heavier;
- “N” is a massive load-bearing corrugated sheet, used for roofs of a huge area. Not suitable for gates due to heavy weight and high cost.
The best choice would be a profiled sheet of grade C8 or C10. The number indicates the height of the wave in centimeters. The thickness of the sheet of this brand is from 0.4 to 0.8 mm. Sashes made from grade C corrugated sheets will weigh from 25 to 40 kg, so they can easily be hung by two people, without the use of special lifting equipment. Due to the fact that one profiled sheet per sash will not be enough, the size is calculated based on the width of the material.
Materials and tools
To do the job well, you will need professional tools
In addition to the welding machine, you will need the following tools and consumables:
- welder's protective mask;
- measuring instrument: ruler, tape measure, building level;
- lubricant for hinges - grease or a composition similar in properties to it;
- An angle grinder will be needed to clean up welding seams and dismantle an incorrectly installed hinge group.
Support pillars are best made from a profile pipe of square or rectangular cross-section. This will ensure the reliability of the structure and facilitate the installation process of the canvas.
Beginning of work
The cylindrical shape of the hinges often makes inexperienced welders wonder: “Does this even weld?” It's cooking. Loops made from a hexagon or tetrahedron are actually more difficult to weld. Using the correct technology, the loops are first welded to special plates. It is advisable to do this on a flat horizontal surface, for example, on an anvil (at the same time, you can attach the “minus” of the welding machine to it). An essential requirement: the plates must be welded to the hinges with a continuous seam.
It is not difficult to choose a suitable size dress. We take into account the weight of the gate and the strength of the material from which they are made and determine by eye what length of welding seam can withstand the weight and not allow the door structure to deform. The plates provide a convenient working “platform” for welding work, and they also serve as distribution plates for the door leaf, which prevents the latter from “breaking” even with the overall heavy weight of the door structure.
Gate installation
Welding of hinges with already welded plates must be done permanently, having previously placed the gate in the “native window”. That is, the gate will have to be fixed “idle” and reach its required position even before the start of welding work. The position of the doors must be checked and double-checked as many times as the average first-grader knows the numbers - at least ten.
Welding work
After a thorough check of the location of the gates and the pre-measured and marked fields for the plates has been made, welding work can begin with the lower hinges on the posts. Vertical welds are the most difficult job for a welder. But thanks to the plates, even an inexperienced welder can handle them. Once one bayonet part of the hinge on the sash is welded, you can use a laser level to verify the correct location of its axis and to determine the exact location of the second bayonet hinge.
Completion
After carefully welding the bayonet parts of the loops on the pole, you will need to attach the inserted upper parts of the loops to them immediately with the balls. Then press the baited part against the door leaf as tightly as possible and continue welding work.
At the end of the welding work, the seams can be processed with a grinder.
This technology has been successfully used by all door installation services for a long time. It will not be difficult to do this yourself if you have welding skills and the necessary equipment with consumables:

Useful tips for welding gate hinges
Incorrect fastening of iron hinges to gates leads to poor operation of the gates. Over time, they will have difficulty moving or may not be able to function at all.
To prevent such troubles, experienced professionals give several useful recommendations.
- When working with straight hinges, it is better to weld on a horizontally lying gate (the leaf can be placed on the ground).
- Before welding, it is recommended to make a backing 1/2 loop long. The part should be placed under the bottom of the loop, and the top should be grabbed from the end side.
- When attaching hinges to a round post, make an external allowance of 5 mm. When working with a rectangular support, fixation is carried out flush.
- Before final fastening, a rectangular block is placed along the hinges and the devices are corrected if they are crooked.
- It is better to weld with small tacks. Actions are performed twice and from all sides.
- Before fixing the hinges from the inside, it is necessary to check the ease of movement of the gate in weight. Incorrect operation is corrected by welding, soldering several points on the outside.
- To avoid sagging of the sashes, before the final welding of the hinges of the fabric, the stand should be closed and placed in the center.
While the hinges are hot, the gate does not open. The structure can be used as soon as the devices have cooled down.
Preparatory work
They start by welding the plates to the hinges. This step can be skipped if you are using ready-made canopies with mounting plates or when mounting them on round poles of small cross-section. The plates are cut from sheet steel using a grinder, choosing sheets with a thickness of at least 5 mm.
Before assembling the hinge, its internal part (the place where the bearing is located) is carefully treated with lubricant, and the area allocated for welding is cleaned of dust and rust. Cook on a horizontal surface. Two plates are laid side by side along the long side with a gap of 2–3 mm. Half of the canopy is placed on top, welded to one of the plates with a continuous seam. A similar operation is performed with the second half. The resulting seams are carefully cleaned.
Important: according to fire safety rules, welding work is carried out either on unpainted or fully painted, dry parts. Paint that is not completely dry can ignite from a spark.
Preparing to install hinges
Any gate is attached to the base using two hinges - lower and upper.
If the trench or support pillars are level, then the upper and lower loops should be on the same vertical line passing through them from top to bottom. In this case, the load on them will be distributed evenly. According to the work technology, thick metal plates must first be welded to the hinges. They are also called plates.
Loop welding diagram
They are welded on some horizontal surface. It is very convenient to carry out work in a vice, to which you can easily connect the neutral wire from the welding machine. To properly weld the plates to the loop, you need to do this in the following sequence:
- 2 plates are laid horizontally, ensuring a gap between them of 2-3 mm.
- A loop is placed on top of the plates, in the center of the gap.
- One of the parts of the loop is welded to the plane of the plate.
- 2 plates are located under the second part of the fastener, after which welding is performed on the other side of the fastening.
Additional recommendations
Failure to comply with the requirements when performing welding activities can jeopardize the final result. To avoid this, just consider the following recommendations:
- Before assembling the hinges, you need to prepare and analyze a diagram showing the placement of the fittings. This minimizes the likelihood of redoing the work.
- Hinges with a straight configuration are best attached to gates placed on a flat surface.
- The gate may only be opened after the seams have cooled completely.
- On round posts the curtain is extended 5 mm outwards, on rectangular posts it is welded flush.
- The seam is made from bottom to top.
Varieties
Hinges allow you to smoothly open and close the gate without making a single sound
All types of loops can be divided into three groups:
- classic;
- decorative;
- hidden.
The first ones have a normal appearance, because the consumer encounters them quite often, since they are installed on entrance and interior doors. Even though we are talking about gate hinges, they are not particularly different. In this case, there is one aspect that plays an important role, this is the special treatment of the material, thanks to which the hinges will withstand any weather conditions.
Increased reliability is one of the most important characteristics during hinge production. This element must withstand heavy loads, because the gate is heavy and is also used regularly. Therefore, additional bearings are often installed to improve the data. You can often find hinges without ears on sale, since the consumer can independently weld them to the product, depending on the structure of the system.
Articulated
Hinges are in great demand and this can be reasonably explained. They allow you to easily and smoothly guide the gate and are resistant to breakage, which is an important indicator. Some of the hinges of this device are designed for installation on large gates, as they can withstand heavy loads. Spontaneous opening and closing is excluded if the structure itself is installed correctly and this fitting option is selected.
For the manufacture of hinges, durable and reliable metal is used, which has excellent performance. Heavy gates will last a long time with this installation.
Hidden
They resemble classic ones, but the main advantage is their increased burglary resistance, and for many this is the main indicator. Removing such gates will be problematic and will also take a lot of time.
Decorative
According to the principle of operation, they do not differ from the classic ones, but they look more aesthetically pleasing and can emphasize the design of the gate installation. Hinges can be antique, forged, or in a certain style. Welded structures are strong, reliable and provide safety.
teardrop-shaped
They take their name from the shape of the bearings, which are an integral part of the structure. Such hinges are in demand during the installation of garage and entrance gates, steel doors and even safes. Thanks to the teardrop shape, the problem of uneven movement is solved, so if you have heavy swing gates, this option will be one of the best. When opening, you will not hear creaking or noise, the structure will move smoothly.
Cylindrical
They are suitable for a massive frame where strength and resistance to heavy loads are required. They have support bearings that do their job for a long time. In such hinges the crown will be hidden in the body.
Adjustable
This type of hinge is distinguished by its ability to be adjusted, which is an indispensable advantage in certain situations. Thanks to them, you don’t have to worry about the sashes jamming. As for the cost, it all depends on the variety you have chosen, as well as the manufacturer, because everyone sets their own prices.
Classification according to GOST
Today on the market you can find a huge number of all kinds of hinges from different manufacturers, shapes, types of fastening, and external design. High-quality hinges for country gates and gates are divided into certain groups according to current GOSTs so that the average person does not get confused when choosing them. This makes it much easier for customers to select the necessary components and navigate their types and prices. Knowing the features of each type, the client can easily choose the right part for fastening the doors.
The main types of hinges for modern gates are the following:
- cylindrical type with support bearing;
- secret type for hidden installation;
- through-type curtains;
- models with a reinforced structure for mounting on gates;
- three-section type for installation in industrial facilities.
Now, let's take a closer look at each of these types in order to evaluate the features of each of them.
When choosing fasteners, it is important to know the advantages and disadvantages of each type, this will allow you to choose exactly the model that is most suitable in a particular situation.
Cylindrical with support bearing
This type is made in a standard form and is not particularly different. Outwardly, they look like a cylinder of two halves. In the first part, which is the top, there is a pin, and in the second, which is the bottom, there is a hole into which the first part is inserted. Some models have a ball-type bearing inside to facilitate movement.
Such curtains are used in structures whose weight does not exceed 400 kilograms. For heavier systems, reinforced special cylindrical hinges are used. The connectors are fastened by welding. The ball bearing is installed in the hole in the lower curtain. Often, on the back side of the bearing there is a hole with a plug that makes it easy to lubricate and clean it. This small revision will improve the performance.
Up to four cylindrical hinges are installed in such structures to ensure the best movement and reduce the load on each. In some models, the bearing is not installed in the lower part, but between two moving elements. This modification greatly simplifies the opening and closing process. However, such a mechanism is difficult to lubricate, since to do this you need to lift one of the flaps.
Secret hinges
The main advantage of this type is hidden installation, because the design reliably hides them inside when the system is closed. A special feature of the design is that the hinge itself is hidden in the sash frame and attached to the side of the support. The advantage of such a fastening system is that it reduces the chances of hacking, because the loop is difficult to find and almost impossible to dismantle without the necessary tools.
Through-type hinges
The design feature of this type is that the two curtains are connected by a rod that enters the upper part and protrudes slightly from the lower part. The simplest design consists of two halves and a pin. This type is widespread on the market and is used mainly for office doors; the design can withstand a weight of up to 200 kilograms.
Assembling elements is somewhat reminiscent of a construction set, because each element has several ears. It is important to note that there can be several such elements on the door, which significantly increases reliability. Sometimes, bearings are installed between the hinge elements, allowing movement to occur more smoothly, with less effort.
To prevent the possibility of hacking by removing the pin, there is a special plug on the bottom. Basically, it is welded, less often screwed.
If the plug is not provided for by the design, then a special limiter is installed on the top part, which does not allow the pin to be removed. This prevents hacking without special tools.
Reinforced gate models
Special reinforced models of cylindrical hinges allow them to withstand greater loads than conventional ones. They are made of metal of greater strength, as a result of which the walls and rods are thicker. This allows you to increase the load-bearing capacity of each loop.
This type has modifications in which bearings are added. They have special markings that indicate increased wear resistance and maximum pressure on them. This makes it easy to open and close heavy gates.
Three-section industrial
This type is in great demand in structures with significant weight of the connected web. Structurally, they are similar to through models, however, they are more reminiscent of cylindrical ones. Their design consists of two oppositely directed pins onto which cylinders are placed and welded to the posts.
It is impossible to disassemble such a structure without using a grinder or other special tool.
How to properly weld hinges on gates - procedure

Loop selection
The correct choice of hinges for metal gates. gates and doors should be based on several factors:
- determining and selecting the type of loop;
- determining the number and overall dimensions of the loop.
Types of loops
First of all, welded hinges differ in shape. They can be:
- cylindrical. A variation of this group is the welded drop-shaped loop;
- square. They are used extremely rarely. Currently practically not produced;
- hexagonal.
The main types of welded loops, differing in shape
Experts recommend choosing cylindrical or teardrop-shaped hinges, since this type is the easiest to install.
All welded hinges can be additionally equipped with a ball that acts as a bearing. The ball makes it easier to open the door and reduces friction, which negatively affects the life of the fittings.
Welded hinge equipped with a ball bearing
Also on sale you can find reinforced welded hinges, which are used for installation on a metal door of large size or weight. Additional plates allow you to evenly distribute the load on the hinge, which increases the service life of the product.
Welded loop complemented by metal strips
The most optimal option for a welded loop is a cylindrical ball loop, supplemented with strips. It is this kind of fittings that will serve for a long time without unnecessary problems.
Requirements and types of hinges for gates
It is necessary to select devices according to the following criteria:
- technology of fastening to the sash;
- building material from which the mounting surface is made;
- weight of the structure;
- width of the gate or gate leaf;
- potential rotation axis and fixture angle.
According to their technical structure, gates are divided into two main functional types:
- lightweight structures - made of wood, can be wicker, plastic, made of corrugated board;
- heavy - they are made from heavy types of wood, steel sheets, and can be forged.
Each of the indicated gate options has its own type of fastening loops and their installation option.
Based on the weight of the installation structures, as well as the construction resource they are made from, you should select fastening loops for the gates.
If you choose the wrong mounting devices, they will not fully cope with their main options - opening, turning and holding the gate . In addition, the loop also has a decorative function: its appearance should harmoniously fit into the overall approach to the design of the gate.
It is these factors, and not the price characteristics of fasteners, that should be taken into account when selecting the necessary structures.
Hinges for gates and gates can be of completely different shapes and types:
- units are made of two and three sections;
- According to the method of fastening, hinges for welding are distinguished, as well as screwed structures (for this, nuts and bolts are used).
The most common and versatile are ball bearing hinges .
In such fasteners, a ball made of high-strength metal is placed between the bottom of the cap and the pin. The idea of the design is to reduce friction in the fastening mechanism and increase its durability. Ball hinges are appropriate only if the gate has a light weight - up to 400 kg (often applicable for metal structures). The fixtures are attached by welding. Another option for hinges is cylindrical reinforced structures , which are additionally equipped with special plates that allow you to evenly distribute the load between the sash and the post. Used for installation on structures weighing up to 600 kg. There are right- and left-handed ones. Such fasteners can be welded, or you can use a screw connection.
