An equal-flange corner is a shaped L-shaped metal product with equal sides (the same length of shelves). It is the most popular and leading type of profile rolled metal products used in various fields of industry and production.
The method of application depends on the type, hardness, width of the sides. The corner can be used during repairs to strengthen concrete structures, in construction as the basis of metal structures, as reinforcement in construction projects, or as a decorative element for decoration.
Corners come in different types, are distinguished by their versatility, low cost, ease of installation, and are manufactured in accordance with state quality standards.

Calculation of angle for deflection and bending
This online calculator is designed to allow you to easily and quickly select the dimensions of the corner depending on the load on it. Its peculiarity is that on one page it is possible to compare equal (GOST 8509-93) and unequal (GOST 8510-86) corners. The latter, in turn, can be selected depending on its location in space, i.e. depending on how it will be oriented relative to the load.
The corners are calculated for bending and deflection (in terms of strength and deformation) for the following design schemes:
Type 1 – single-span simply supported beam with a uniformly distributed load. Example: a corner lintel that carries floor slabs and a low masonry height. (For more information on calculating corner jumpers, see this calculator).
Type 2 – cantilever beam with rigid embedding and uniformly distributed load. Example: a reinforced concrete canopy made using an angle that is rigidly (using stiffeners that limit any turns) welded to a reinforced concrete wall.
Type 3 – single-span hinged beam with a cantilever with a uniformly distributed load. Example: the same canopy as in the previous diagram, only here the corner is inserted into the wall on one side and rests on a brace on the other (blue in the picture).
Type 4 – single-span simply supported beam with one concentrated force. Example: a lintel on which one floor beam rests.
Type 5 is a single-span simply supported beam with two concentrated forces. Example: a bridge supported by two concentrated forces.
Type 6 – cantilever beam with one concentrated force. Example: the canopy of a house with a brick wall on it, built in an African republic (where it never snows) according to the imagination of an African architect. The corners of this canopy are firmly embedded in the wall, as described in the second diagram.
Note: the calculated angle in the example drawings is colored red.
Calculation of angle for deflection and bending
Using this calculator, you can not only easily calculate the angle for deflection and bending, but also select the optimal one from equal and unequal angles.
How to calculate the weight of 1 meter of corner 100x100x7: instructions
Corners are made in accordance with the requirements of GOST standards. During their production, possible deviations are taken into account, which are also specified in the relevant regulatory documentation. To calculate a corner with dimensions of 100x100x7 mm, the easiest way is to refer to a special table. In GOST, which regulates equal-flange products, the mass of 1 m of this product is 10.79 kg.
The easiest way to calculate the weight of a corner 100x100x7 is to refer to the table
It is important to remember that in order to correctly calculate the mass, it is necessary to accurately determine the thickness of the walls of the product, otherwise the final value will be incorrect. Parts with these dimensions may have different thicknesses. For example, the weight of a corner 100x100x8 will be greater than that of a product whose thickness is 7 mm.
There are tables that contain information not only about the theoretical mass of 1 linear meter. m of products, but also about how many meters are contained in 1 ton of steel. Calculations in such tables are made taking into account the norms of state standards. The document regulating equilateral steel products is GOST 8509-93.
Rolled steel is very popular, the width of the shelves is 100 mm and the thickness is 8 mm. The weight of 1 meter of corner 100x100x8 is 12.25 kg.
In order to correctly determine the mass, you need to know the thickness of the corner walls
Uneven-flanged products also have corresponding standard documentation, which contains tables with all the necessary data. For greater accuracy, you can determine the mass yourself using the appropriate formula. The equation in this case is as follows: py = [(A + B - t) * t + (1 - π/4) * (r² internal – 2 * r² external)] * ρ, where: t is the side thickness indicator; A - shelf width (large); B - width of the shelf (small); ρ—steel density; r internal – radius of internal rounding of the sides; r external – radius of external rounding.
When using the formula, it is recommended to check the accuracy of the calculations several times. This is due to the fact that when calculating independently, errors in numbers are often made.
Calculation of the weight of a corner 75x75x5 (per meter): quick methods of determination
The standard sizes of these products are prescribed in GOST, however, manufacturing ideal products in accordance with these standards is a rather complex process. As a rule, finished products have certain errors. It is important that the deviation from the ideal size is within the limits specified in state standards.
Using the table, you can easily and quickly determine the mass of 1 m of a 75x75x5 corner
The weight of 1 meter of a corner 75x75x5 mm is a theoretical value, for which there are several ways to determine. The simplest of them is tabular. In addition, you can quickly find the desired value using an online calculator. The weight of 1 m of a corner with these standard dimensions is 5.8 kg. If necessary, you can independently calculate this indicator. The theoretical mass is calculated using a special formula.
Helpful information! For equilateral products, equations are used that are not suitable for determining the 1 m mass of unequal-sided parts.
Using the above methods, you can find out the mass of products of the same width, but having different thickness indicators, for example, steel angles 75x75x6. The weight of 1 meter of these parts is 6.89 kg.
Calculating the weight of 1 meter of corner 63x63x5 mm: recommendations
Equal-flange steel products with such dimensions are used for the installation of a variety of engineering and construction elements. It is worth noting that the length of such parts according to GOST varies from 4 to 12 m. To calculate the theoretical mass of the product, the easiest way is to use the table.
The weight of the product 63x63x5 per 1 m is 4.81 kg, thanks to these data you can easily calculate the mass of the batch
The weight of the corner 63x63x5 (per meter) is 4.81 kg. Knowing this figure, it will not be difficult to determine the mass of the batch. Corners of this size are used as independent building elements or as additional reinforcements for various structures. Many people use these products to build fences on private plots.
The mass of a corner having similar dimensions should be known. This indicator allows you to calculate transport costs, as well as determine the number of parts required for the construction of a particular structure. As a rule, the actual weight of products of this type differs from the specific weight by approximately 5%. This is due to the fact that, in accordance with GOST, the width tolerance for a corner 63x63x5 mm can reach 1.5 mm. The weight of a corner 63x63x5 is calculated very quickly if you use special documentation.
The estimated weight of the corner is 50x50x5 per meter according to the state standard
In addition to standard data, which includes the specific gravity of 1 m of a product, other indicators are used for calculations. The corner, the sides of which are 50 mm wide, is the most popular product today. Such dimensions contribute to the high versatility of this part.
The mass of a batch of steel angles 50x50x5 can be quickly calculated using GOST data
In order to calculate the weight of 1 meter of a 50x50x5 corner, you need to familiarize yourself with GOST, which regulates this type of rolled metal. Like all of the above products, this corner belongs to the category of equilateral (or equal-shelf). It is used in the installation of fences and is also common in furniture production. The use of such products allows you to create a perfectly even angle, which is a big plus when assembling cabinets and other pieces of furniture.
The maximum thickness of this part is only 5 mm. However, this product has good strength characteristics, which makes it possible to use them in engineering structures of varying degrees of complexity. The weight of a corner 50x50x5 mm is 3.769 kg (1 m).
Note! A ton contains 265.25 m of steel products with similar dimensions. Knowing this value, you can easily calculate their number, as well as calculate the total mass of the batch.
The weight of a metal corner per meter 50x50x5 is 3.769 kg
The length of such parts may vary. The length range is from 4 to 12 m. These are standard indicators that can be compared with almost any type of equilateral rolled metal.
State documents are used not only to determine the weight of 1 meter of 50x50x5 corner. GOST contains all the necessary data, including possible deviations from the norms. This information includes the accuracy class, as well as steel grades that exist and are approved within the framework of modern industry.
Corners whose sides are 50 mm wide can have a different thickness. For example, products in which this indicator is 4 mm are popular. The weight of 1 meter of corner 50x50x4 is 3.05 kg.
How to independently determine the weight of a 50 mm corner and other types of products?
Steel corners are classified according to the width of the sides. According to this indicator, all parts are divided into two types: equal-flange and unequal-flange. In the first case, the product has identical sides, and in the second, one of the sides prevails in width.
Equal steel angles have the same side sizes
The weight of steel angles is a necessary parameter for carrying out construction and transport calculations. This indicator is influenced by many factors. First of all, the mass of parts belonging to this group of rolled metal products depends on the dimensions of the products. And also the method that was used in the production of these parts has a great influence on the amount of weight.
In order to determine the weight of a metal corner, you must first find the mass of 1 meter of the product. This calculation is made using two indicators: cross-sectional area and specific gravity. These values need to be multiplied. Each standard size of steel parts has its own specific gravity, which is determined in different ways. Another common method for finding this parameter is using special tables that can be found in the relevant GOSTs.
For unequal metal corners, one of the sides is larger in size
The exact weight of a steel product of this type can only be determined by weighing. However, this method is not always convenient. To find the estimated mass of a batch of corners, you must first calculate the weight of 1 meter. The easiest way is to use special tables that contain data on all standard sizes of steel products of this type. First of all, you need to measure the width of the sides (shelves). It is also necessary to determine the thickness of these same sides.
To determine the exact mass of a batch of corners, you must first calculate the weight of 1 meter
Using the above data, you can easily find the standard size you are interested in in the table and see the weight of 1 linear meter. m of product (for example, the weight of a corner is 50x50 mm). Then you need to divide the resulting theoretical mass by the density of the steel, the average value of which is 7850 kg/m³. The next step is to multiply the result by the density of the steel grade.
If necessary, you can carry out an independent calculation in full. However, this calculation may be inaccurate because it does not take into account the radii of curvature between the sides. The process of independently calculating the weight of a 63 mm corner (or any other) consists of several stages.
First of all, it is necessary to determine the cross-sectional area of the part. To do this, you will need to measure the length of one side (shelf) and multiply the resulting figure by the thickness. Next, you need to subtract the thickness of the product from the length of the second side, after which the resulting number is multiplied by the thickness. This determines the cross-sectional area of one and the other side.
After calculating the area of the sides, you need to add these two indicators. The result is the total theoretical cross-sectional area of the steel angle. All that remains is to multiply this value by the density and 1 m. This way the theoretical weight of 1 m of the steel part is determined.
You can determine the weight of the corner yourself, but the calculation may be inaccurate
Steel equal angle: GOST
The documentation regulating the production of products reflects the physical properties and manufacturing methods, indicates product parameters and permissible deviations from the established norm. This takes into account the dependence of permissible deviations on wall dimensions and accuracy indicators.
GOST
GOST No. 8509-93 applies exclusively to hot-rolled equal-flange steel angles. And GOST No. 19771-93 regulates the production of the same, but bent corners. Both documents establish categories of product accuracy, its physical characteristics, and permissible deviations from standards.
GOSTs contain information about materials that can be used in manufacturing. These materials, in turn, must also comply with GOST requirements.
The documents contain tables and figures with section values, mass, and weight of one linear meter of products. The tables were compiled taking into account the profile area, thickness and width of the flanges, radius of curvature, reference value of metal density, and nominal dimensions. But such calculations usually do not take into account deviations that are inevitable in the production of rolled metal.
Assortment
The assortment of rolled metal products is a detailed classification of metal products grouped by size, physical characteristics, quality, and other characteristics. The range of equal-angle angles corresponds to GOST 8509-93. It contains tables with corner dimensions, cross-sectional areas, and reference indicators.
The assortment is used for accurate calculation of materials, which allows you to use building materials correctly, avoid overuse, and carry out effective interaction with suppliers.

Beam calculator - calculation for different types of structures
Beams in a house usually belong to the rafter system or floor, and in order to get a reliable structure that can be operated without any fear, you need to use a beam calculator.
What is the beam calculator based on?
When the walls have already been brought under the second floor or under the roof, it is necessary to make a ceiling, in the second case smoothly turning into rafters. In this case, the materials must be selected so that the load on the brick or log walls does not exceed the permissible value, and the strength of the structure is at the proper level. Therefore, if you are going to use wood, you need to choose the right beams from it and make calculations to determine the required thickness and sufficient length.
Beam calculator
The subsidence or partial destruction of the ceiling can be due to various reasons, for example, too large a step between the lags, deflection of the cross members, too small their cross-sectional area or defects in the structure. To eliminate possible excesses, you should find out the expected load on the floor, be it basement or interfloor, and then use a beam calculator, taking into account their own weight. The latter can change in concrete lintels, the weight of which depends on the density of the reinforcement; for wood and metal, with a certain geometry, the weight is constant. The exception is damp wood, which is not used in construction work without first drying it.
Beam systems in floors and rafter structures are loaded by forces acting on section bending, torsion, and lengthwise deflection. For rafters, it is also necessary to provide for snow and wind loads, which also create certain forces applied to the beams. You also need to accurately determine the required step between the jumpers, since too many crossbars will lead to excess weight of the floor (or roof), and too little, as mentioned above, will weaken the structure.
How to calculate the load on a floor beam
The distance between the walls is called a span, and there are two of them in the room, and one span will necessarily be smaller than the other if the shape of the room is not square. Interfloor or attic floor lintels should be laid along a shorter span, the optimal length of which is from 3 to 4 meters. Larger spacing may require non-standard sized beams, which will result in some unsteadiness of the deck. The best solution in this case would be to use metal crossbars.
Regarding the cross-section of a wooden beam, there is a certain standard that requires that the sides of the beam have a ratio of 7:5, that is, the height is divided into 7 parts, and 5 of them must make up the width of the profile. In this case, deformation of the section is excluded, but if you deviate from the above indicators, then if the width exceeds the height, you will get a deflection, or, if the opposite discrepancy occurs, a bend to the side. To prevent this from happening due to the excessive length of the beam, you need to know how to calculate the load on the beam. In particular, the permissible deflection is calculated from the ratio to the length of the lintel as 1:200, that is, it should be 2 centimeters per 4 meters.
To prevent the beam from sagging under the weight of logs and flooring, as well as interior items, you can grind it from below a few centimeters, giving it the shape of an arch; in this case, its height should have an appropriate margin.
Now let's turn to the formulas. The same deflection mentioned earlier is calculated as follows: fnor = L/200, where L is the span length, and 200 is the permissible distance in centimeters for each unit of beam subsidence. For a reinforced concrete beam, the distributed load q on which is usually equal to 400 kg/m 2, the calculation of the maximum bending moment is performed using the formula Mmax = (q · L 2)/8. In this case, the amount of reinforcement and its weight is determined according to the following table:

Security in the house is not only video surveillance, but also strong walls and ceilings, which means that during construction it’s a good idea to use a beam calculator
Using an online calculator to calculate your weight
A special online calculator is programmed to find the weight of one product. After obtaining the desired value, it becomes possible to carry out further calculations. An online calculator can be found on the Internet using the search bar of your browser. This method allows you to quickly and accurately calculate the required weight of 50x50x4 mm corners and other popular types of rolled metal.
In order to perform the calculation, you will need to enter the dimensions of the part in the appropriate cells. It is necessary to know the length of the product, as well as the thickness of the shelves, the width of the corner and its height. For maximum accuracy, it is recommended to indicate the grade of steel from which the part is made.
This program performs automatic calculations using a special formula. This equation has the following form: m = ρ * S * (A + B - S) * L, where: ρ – steel density indicator; S – wall thickness; A and B – shelf dimensions; L is the length of the product.
Thanks to the online calculator it is possible to calculate the weight of one product
Note! It is important to remember that the weight of a corner of 75, 50 mm (or any other) is a value that is primarily a reference. Thus, the online calculator first synchronizes with tables located in state standards, and only then calculates the required parameter using the formula.
In most cases, the data entered can be easily found in special tables. Most often, the mass of products that are very popular due to the many applications is calculated. If the calculator does not find the required part in the table, then it is necessary to calculate using the formula.

GOST 19772-93. Bent steel angles unequal
We calculate the weight of rolled sheets
Calculating the weight of rolled metal is a fairly simple task of this class. Simplicity is determined by the shape of the sample being studied. To begin calculations, you need to know the following characteristics:
- geometric dimensions of the test sample;
- metal density (for steel you can use the average indicator, which is equal to 7850 kg/m 3);
The first stage involves calculating the weight of a sheet of metal with an area of one square meter and a thickness of one millimeter. The volume of this sample is calculated and multiplied by the density of the steel. It is obtained by standard multiplication of three geometric parameters: length, width, height. Multiplying the result by the density, we get a value equal to 7.8 kg/m3. It will allow you to calculate the weight of a sheet of any geometric size and shape. Convenient because it does not depend on length, width, thickness. You can get the final value without resorting to preliminary recalculation. Therefore, the main task will be to calculate the volume of the selected sheet.
For example, the weight of a sheet whose size is one meter long, two meters wide, 0.35 mm thick will weigh 5.5 kg. A sheet 5 mm thick, measuring 1.5 m wide and 6 meters long will weigh 353.25 kg.
Before using a metal sheet as a ceiling or building structure, you should evaluate its weight.
Sheet weight
Angle weight: nuances of determining the mass of a linear meter
Manufacturers engaged in the production of this type of rolled metal are required to comply with the requirements and standards prescribed in the relevant GOSTs. It is important to note that the tables that can be found in the regulatory documentation indicate the theoretical mass of 1 linear unit. m details. In turn, the calculated weight is a value that is almost impossible to obtain.
To find the actual mass of a product, there is only one way - weighing, which is not entirely convenient. The most common type of product has two sides, the width of which is 50 mm. The weight of a corner 50x50x4 per meter can be calculated independently or using a special program for this.
It is also worth understanding that average values of metal density are used for calculations. For products made of steel, a constant value applies, which is 7850 kg/m³. However, currently there are many grades of steel, each of which has an individual density indicator that differs from the others. Thus, the weight of a batch of corners is calculated using average values, which is reflected in the final figure.
The mass of a linear meter of a corner can be calculated independently or using a special program
Among other things, steel angles can have different accuracy classes (A, B, C). Permissible discrepancies with the accepted dimensions specified in GOST standards also affect the calculation of weight. This leads to the following conclusion: regulatory documentation contains information about specific gravity, which, as a rule, does not correspond to the actual one. Nevertheless, GOST standards are relied upon when carrying out all necessary calculations. Manufacturers also rely on this documentation.
Independent calculations are often necessary when installing various fences and frame structures with your own hands. In this case, a special place is given to a product that has the following geometric indicators: 50, 50, 5. It is recommended to look for the weight of a corner of this type using tables that are indicated in the regulatory documentation.
Helpful information! The production of steel angles takes into account the percentage of scrap, which in any case is formed during the manufacturing process. Unscrupulous manufacturers deliberately reduce the wall thickness, making the product more susceptible to load. If you purchase low-quality products and when calculating them, the final figure will differ greatly from the actual weight of the product. This is especially true for calculations of large parties.
Specific Gravity Calculation
Today, many methods and algorithms have been developed for measuring and calculating not only density, but also specific gravity, which make it possible to determine this important parameter even without the help of tables. Knowing the specific gravity, which differs between different alloys of copper and pure metal, as well as the density value, you can effectively select materials for the production of parts with given parameters
It is very important to carry out such measures at the design stage of devices in which it is planned to use parts made of copper and its alloys
Specific gravity, the value of which (as well as density) can be seen in the table, is the ratio of the weight of a product made either from metal or from any other homogeneous material to its volume. This relationship is expressed by the formula γ = P/V, where the letter γ denotes specific gravity.
Specific gravity and density, which are inherently different characteristics of a metal, should not be confused, although they have the same meaning for copper.
Knowing the specific gravity of copper and using the formula for calculating this value γ = P/V, you can determine the mass of a copper billet having a different cross-section. To do this, it is necessary to multiply the specific gravity value for copper and the volume of the workpiece in question, which is not particularly difficult to determine by calculation.
Calculation of corner weight: tables of state standards
The tabular method for determining the mass of 1 m of a steel part is the most popular. This is explained by the fact that these schemes contain ready-made data that was calculated specifically for ease of use of the values. Similar tables can be easily found on the Internet. They are part of the regulatory documentation (GOST).
Note! There is a separate standard for each type of rolled steel.
Such tables are used when you need to quickly determine the mass of a small or large batch of angles. In order to find the total weight, it is necessary to take the value that corresponds to the mass of 1 linear meter. m of steel part, and multiply this figure by the total footage. Thus, the weight of 1 meter of corner plays a decisive role. The table allows you to find this theoretical value without wasting time and effort. Such schemes allow for reverse calculation. For example, if a person knows the mass of a batch of steel angles, then using this data one can determine the total length of all products.

Methods for calculating a metal corner, weight table, product features
Angle steel is the most popular type of shaped steel. According to the production method, it is divided into hot-rolled and bent. Source materials: ordinary quality carbon steel St3 ps/sp (for ordinary use), high-quality, low-alloy steel 09G2S, 17G1S, 10HSND, 15 KHSND (for products used under high loads, in difficult temperature conditions, in contact with aggressive environments).
Characteristics of hot rolled metal angle
Equal-flanged hot-rolled steel angles are produced in accordance with GOST 8509-93 from a square, which is the original workpiece. The most widely used angular profile of normal accuracy is “B”; for critical structures, high-precision products “A” are used. The shelf dimensions, according to the standard, are from 20 to 250 mm.
The range of unequal corners is determined by GOST 8510-86. The smallest shelf sizes are 16 and 25 mm, the maximum are 125 and 200 mm. These products are used to create structures of complex shapes, such as arches.
Hot-rolled products are characterized by high strength, which allows them to be used in structures designed to operate under high load conditions. In the production of corner profiles, carbon steel of ordinary quality and high quality is widely used. Products made from low-alloy steels are used to create critical structures of housings, frames and other parts of agricultural machinery, locomotives, cars, large-sized construction machines and mechanisms. Products made from this profile can maintain performance characteristics over a wide temperature range - from -70° to +70°C, with serious daily and seasonal temperature changes.
Hot-rolled products are supplied in batches, the size of which usually does not exceed 70 tons. Each batch has a certificate of compliance with regulatory requirements.
Calculation of the quantity of steel equal angle angle
When determining the mass of a batch of rolled corner profiles, you need to know the mass of a linear meter, which you can determine from the table, and the total footage.
Weight table for equal flange hot-rolled steel angles of the most common sizes
Methods for calculating a metal corner, weight table, product features
The article describes methods for calculating a metal corner and its characteristics. A table of weights is provided.
Types of equal angle corner
Equal angles are classified according to the following criteria:
- mode of production;
- precision manufacturing;
- length.
Mode of production
There are two main types of equal angle angles, determined by the production method. These are the corners
- obtained by hot rolling;
- representing bent products.
Hot rolled products
Thus, an equal-flange angle GOST 8509-93 is made from rolled sections of suitable size using the hot rolling method. In this case, certain rolled products of square shape are used.
As a rule, low-alloy or structural steel is used. Its use complies with the current GOST 19281−89. It applies to rolled products made of high-strength steels. Such products can be used without additional heat treatment.
Bent corners
The corner GOST 19771-93 is a bent equal-flange corner. It is considered as a separate type of this product. It is produced using special machines by bending a strip of cold-rolled or hot-rolled sheets. The production uses carbon steel of ordinary quality, high-quality structural steel, and low-alloy steel.
Bent corners are characterized by lower strength and smaller tolerances for deviations specified in GOST, assortment, and other technical documentation. Although in reference books such products have the same names as rolling angles.
Manufacturing accuracy and length
Only equal angles from 4 to 12 meters can be classified by length. These are measured products. Moreover, each type of measured products has certain tolerances for the volume of unmeasured length (no more than 5% of the lot). The unmeasured length has a size of 3-12 meters and an error tolerance of up to 70 cm.
The manufacturing accuracy of the shelf width determines the production of corners of the following types:
- type A (maximum accuracy);
- type B (increased accuracy);
- type B (normal accuracy).
In addition, the shelves of the corners must be located strictly perpendicular to each other within the permissible values according to GOST. The thickness of the shelves is also indicated in GOST and may have permissible deviations. The type of corner determines its main parameters and characteristics.
Product characteristics and features
The main characteristics of the corners include the weight of one linear meter and the cross-sectional area. A feature of this type of rolled product is considered to be high strength and rigidity of the product with a low weight of the profile. An equally important indicator is high manufacturing precision. This feature is taken into account to obtain an ideal even angle.
Production Features
Angle bars are produced on automated production lines. The raw material for hot-rolled angles is steel ingots. The cube-shaped bloom is heated to the temperature of metal recrystallization and fed to rolling rolls. Under the influence of high pressure, soft metal is transformed into a product of the desired shape with specified parameters.
The advantages of this hot rolling technology include the following factors:
- production of rolled products without size restrictions;
- large thickness of processed workpieces;
- high speed of production of products.
Products made using this technology are distinguished by the accuracy of linear parameters and have high quality characteristics. Metal products have a smooth surface without visible or hidden defects and are characterized by increased bending strength. Steel that has undergone heat treatment has a uniform structure and has the necessary ductility. The area of use of hot-rolled angles depends on the type and size of the product.
Why do you need to calculate mass?
Accurate calculation of metal mass allows:
- take into account the obtained data during construction, installation of pipes and utilities;
- find out the total weight of the batch when transporting from the warehouse.
The actual weight of the rental may vary, since the calculator works based on accurate data. In production, small deviations from the exact geometric dimensions are possible, which is reflected in the weight. The larger the batch, the more noticeable the deviation.
The program, which operates online, is periodically updated and supplemented with information regarding new steel grades. If you do not find the brand you need in the list, contact us, we will add it to the calculator list.

Metal weight reference tables – Rolled unequal angles
Angles are produced by hot-rolling metal or bending cold-rolled and hot-rolled sheets of metal. In hot rolling, the workpiece is formed to the required dimensions and passed under pressure through a rolling mill. Bent corners are produced on profile bending machines.
Steel angles are used for mounting frames, strengthening concrete structures, and creating platforms for various purposes. In this case, cold-rolled angles made of ordinary steel are used for finishing, and hot-rolled angles are used for load-bearing structures.
Along the length of the edges of the shelves:
