Technical characteristics of steel sheet

One of the most popular types of rolled metal products is steel sheet. It can be used as a finished product or as a blank for further production. When choosing sheets for certain purposes, it is worth taking into account the types, technical characteristics and features of the manufacture of flat rolled metal.

The scope of application of metal sheets is extensive, and their properties and characteristics largely depend on the manufacturing method. Thus, the forming of rolled steel can occur using hot or cold rolling methods.

Hot deformation is carried out by heating the metal to temperatures exceeding the conditions for its recrystallization and constituting 60% or more of the melting temperature. The heated workpiece is rolled between rollers, and after molding it is processed, removing possible defects and traces of scale. The size of hot-rolled sheet is regulated by GOST 19903-2015, according to which rolled products have a thickness of no more than 25 mm, with a width of 500-2200 mm.

Hot-rolled sheets are not distinguished by high precision and surface smoothness, but their availability allows the use of such metal throughout the national economy, in many types of construction and production, including as blanks for the production of expanded metal sheets, welded beams, electric-welded and profile pipes and corner.

The cold rolling method involves forming metal with rollers without preheating, which requires more time and effort. The result is a sheet with a smooth surface, high bending, tensile and tearing strength. The production of cold-rolled sheets is regulated by GOSTs 19904-90, 9045-93, 16523-97, according to which their thickness varies from 0.28 to 5 mm, and width from 500 to 2350 mm.

Such rolled products are in demand in construction, the space industry, machine and shipbuilding, and as blanks in the production of tableware, furniture, equipment, household appliances and tools. Applying a zinc layer increases the anti-corrosion properties, which is used in the manufacture of corrugated sheets.

When marking steel sheets, their varieties are taken into account according to several criteria:

• Type of rental:

— hot-rolled – hot-rolled, cold-rolled – cold-rolled;

— OTs – galvanized, OK – with polymer coating, PC – for painting;

- rhombus, lentil - for corrugated sheet GOST 8568-77.

• In terms of rolling accuracy: A – increased, B – normal.
• Surface evenness: PO – especially high, PV – high, PU – improved, PN – normal.
• The dimensional parameters of the sheet are indicated in numbers, in millimeters.
• Edge processing: NO – unedged, O – edged.
• Surface finish: I – extra high, II – high, III – increased, IV – normal.
• Surface: T – etched, GL – glossy, M – matte.
• Drawing properties: VOSV - very complex, OSV - particularly complex, SV - complex, VG - very deep drawing.
• The presence of a crystallization pattern in galvanized sheets: KR - yes, MT - no.
• For profiled sheets: N – for flooring, NS – for flooring and wall railings, C – for wall railings.
• Strength class: 295; 315; 345; 355; 390.

The marking also indicates the steel grade with the designation St, and the GOST or TU number to which the specified parameters correspond.

Calculation of sheet metal weight

If there is no possibility of direct weighing, the weight of scrap metal can be determined in other ways.
The most accurate result will be given by calculation, but other possibilities should not be neglected. So, in order not to burden readers with unnecessary formulas, which will still be there, but below, we will immediately designate the formulas for calculating the most popular products from rolled steel and pipes - rolled pipes.

Here you will not find an online calculator for calculating weight, only formulas that you remember once you no longer have to use special calculators.

For example, when dismantling metal structures or a chimney, you don’t always have a computer, the Internet or a reference book at hand, but the structures are all welded from rolled steel here and our formulas will help out!

Formula to calculate pipe weight

M=(Ds)*s*0.02466

, Where

• M—weight of one linear meter of pipe, kg;
• D is the outer diameter of the pipe being calculated, mm;
• s—pipe wall thickness, mm;
• 0.02466 is the coefficient for a steel density of 7.850 g/cm3.

This formula is very accurate. You can calculate the weight of the pipe and compare the calculated weight with the theoretical one in any range and the value according to the formula will be more accurate! You can also calculate

Calculating the weight of a sheet of metal

M=S*7.85

, Where

• M—mass of steel sheet, kg;
• S is the area of ​​the calculated sheet, in square meters;
• 7.85 - weight of a sheet 1 mm thick and 1 square meter in area, in kilograms

This way you can calculate the weight of a sheet of metal of any size, for which you can calculate the area. The accuracy of calculations using this formula is higher than the theoretical mass in reference books, because

in the assortment, when calculating the mass of metal, the program rounds the values. Well, how can you find out the area of ​​a sheet (of any shape - square, rectangle, parallelepiped, trapezoid, rhombus, etc.)

) - every person who graduated from high school should know.

How to calculate the weight of reinforcement and rod

For a circle, rod, smooth reinforcement, the formula for calculating the mass will be as follows:

M=(0.02466*D2)/4

, Where

• M—weight of 1 linear meter of circle/reinforcement/rod, kg;
• D—circle diameter;
• 0.02466 - coefficient for steel density equal to 7.850 g/cm3

To calculate the weight of corrugated reinforcement (A2, A3), you can and should use the same formula! There will be no discrepancies with the theoretical mass, despite the different cross-sectional designs.

It is, of course, impossible to calculate such a pile of scrap metal using formulas without weighing

General approaches or a little boring theory

To determine the weight of any object, simply multiply its volume by its specific gravity. If everything is more or less clear with specific gravity, then volume is more difficult to determine (if you do not consider such simple shapes as a cube). The most general principle for calculating volume is Gulden's principle, when the cross-sectional area of ​​an object is multiplied by its height.

There are also usually no problems with the height of the metal structure; it is easy (or almost easy) to measure directly, especially if the height section is constant. This can be done for steel pipes of any section and profile, I-beams, channels, angles, etc.

We will consider the method for determining the mass of metal objects of complex and variable shapes later.

Volume of the pyramid

The pyramidal ends of the tops of forged steel fences, deflectors and other parts of metal structures are often found. The volume of the pyramid can be easily calculated using the formula:

, Where:

• B is the area of ​​the base of the pyramid;
• H – height of the pyramid.

Since in technology the bases of a pyramid can be a square, a rectangle or a triangle, the problem can be solved quite simply.

Volume of a truncated pyramid

The enclosing caps, protective latches and doors have the shape of a truncated pyramid. In such situations, a dependency is used:

, Where:

• h – height of the truncated pyramid;
• F is the area of ​​its larger base;
• f is the area of ​​the smaller base.

If the pyramidal part of the structure sold for scrap is somewhat deformed, then the missing volume is added or removed from each side.

Volume of wedge and obelisk

The wedge in the technique is often a pentahedron, the base of which is a rectangle, and the side faces are isosceles triangles or trapezoids. The formula for calculating the volume of a wedge is:

, Where:

• a – side of the base of the wedge foot;
• а1 – width of the wedge top;
• b – wedge thickness;
• h is the height of the wedge.

An obelisk is a hexagon, the base of which is rectangles located in parallel planes. The opposite faces are symmetrically inclined to the base of the obelisk. Volume of this geometric body:

, Where:

• a and b – dimensions of the length and width of the larger base of the obelisk;
• and a1 and b1 – the smaller base of the obelisk;
• h – height of the obelisk.

Volume of rod and pipe

To calculate all geometric sections based on a circle, you cannot do without the parameter π – 3.14 (higher accuracy is not required for scrap metal). Then for the cylinder we have:

, Where:

• R – rod radius;
• H – rod length/height.

For a pipe (hollow cylinder), the volume is calculated by the formula:

, Where

r is the inner radius of the pipe.

Volume of a cone and truncated cone

The geometric shapes of cone and truncated cone are widely used in the design of parts of mechanisms and machines. The volume of the cone is:

, Where

• R – radius of the cone base;
• H is the height of the cone.

To calculate the volume of a truncated cone, a more complex relationship is used:

, Where

R is the radius of the smaller base of the cone.

Volume of spherical elements of metal structures

In addition to the sphere itself, in practice we also have to calculate the volume of the spherical segment and sector. The following dependencies are used:

Volumes of rolled profiles

Most often it is necessary to determine the weight of tees, I-beams, channels, and angles. The following dependencies are used for this:

For the brand

,where b and b1 are the width of the shelf and wall of the tee, respectively; h and h1 – thickness of the base and flange of the tee; H – height of the T-bar fragment;

For I-beam

,where H is the height/length of the I-beam; a – I-beam wall thickness; с and с1 – thickness of the I-beam flange at the base and at the end, respectively;

For the corner

,where H is the length of the corner; l1 – angle thickness; h1 and h2, respectively, are the width of each shelf.

CALCULATION OF THE WEIGHT OF STEEL SHEET

Calculation of the mass of a steel sheet of metal is carried out using a conventional calculator using the formula: P = H*B*L* 7.85
P - theoretical weight of the steel sheet, kg L - length of the metal sheet in linear meters, m; H—sheet thickness, mm; B—width of rolled sheets, m; 7.85 kg/dm3 – steel density, specific gravity – corresponds to the weight of a square meter of steel 1 mm thick.

The weight of sheet metal is calculated in kilograms (kg), if the dimensions of the sheet thickness are substituted into the formula for calculating the weight of a sheet of metal in millimeters (mm), and the length and width of the sheet in meters (m). Knowing the weight of a sheet, you can calculate how many sheets are in a ton or pack of a certain mass.

The weight of galvanized sheet will differ slightly from black, because... The thickness of the zinc coating is several micrometers.

The actual weight may vary slightly due to the heterogeneity of the steel and geometric tolerances, according to GOST of the Russian Federation, on the steel sheet.

How to calculate the mass of a sheet of metal? — Metals, equipment, instructions

Of all the rolled products of metallurgy, it is easiest to determine the weight of a steel sheet: the formula for finding the volume of a rectangular parallelepiped, which is a plate, is known from a primary school course: length, width, height. It remains to multiply the resulting product by the density of the metal, and the calculated weight will be obtained. But in some cases this calculation scheme does not work.

When purchasing sheet metal, you have to deal with the weight of individual plates, whether they are purchased by quantity or by the total weight of the steel surface that needs to be built.

This need is associated not only with setting prices, but also with hiring lifting equipment when performing loading and unloading operations.

Usually calculations are done with a calculator in the following sequence:

• establish the specific gravity of the sheet material - if it is steel, then the density is 7.85 t/m3;
• determine the volume of a single plate and multiply by their number, or the total area of ​​the metal - by the thickness;
• the final result - the calculated weight of steel is obtained according to the formula P = V * 7.85 with dimensions in tons, if the values ​​​​were taken in meters.

Example: sheet steel, the weight of 1 m² of a 10 mm thick plate will be 1 * 0.01 * 7.85 = 0.0785 t, or 78.5 kg.

When manufacturing rolled sheets, tolerances are established for maximum deviations of dimensions from the nominal parameters.

As a result, errors are obtained between the calculated values ​​of the metal mass and the actual values ​​obtained as a result of weighing. The wider the tolerance field, the greater the difference.

Another factor influencing the weight of sheet steel is the presence of coating on galvanized rolled metal or corrugations and perforations on certain brands of products. To help customers, manufacturers and suppliers place an automatic calculator on their websites that greatly simplifies calculations.

If the weight of a sheet of metal is known, it is easy to calculate the number of plates in a ton or pack indicating the mass.

Sheet Metal Materials

Flat products are used in many industries - both in load-bearing structures and for decorative and finishing purposes. In addition to steel, the following raw materials are used for its production:

• aluminum;
• copper;
• zinc;
• alloys.

Metal sheets are often used as roofing, fastening the plates together with folds manually or using tools. All listed materials are suitable for this purpose. In addition to zinc, which is not used in its pure form: it is sprayed onto steel, or alloyed with copper and titanium - the so-called titanozinc is obtained. '

Naturally, the weight of the products of each metal will differ significantly, because the density of aluminum is 2.72, copper 8.3–8.9, zinc - 7.13, titanium 4.51 t/m3.

Types of flat rolled steel

Due to their excellent structural properties, flat rolled iron alloys have become widespread. There are several parameters by which sheet steel is divided:

• thickness - thin plates 0.35–3.99 mm and thick ones over four up to 160 mm;
• technology - cold- and hot-rolled with markings ХК, ГК, galvanized, stainless steel and expanded metal sheets;
• purpose - electrical, shipbuilding, armor, boiler, heat-resistant and other types of steel;
• the profile can be straight, stamped or corrugated, including for roofing tiles.

Flat steel is used mainly in mechanical engineering and construction. Requirements for sheet metal are determined by the conditions in which it will be used.

Features of steel sheets

In practice, classification is most often used based on manufacturing technology. Brief characteristics of flat rolled steel:

1. The galvanized type is made from the same metals. The ferrobase is coated with the Zn element completely or on one side. They produce several types: corrugated sheets, smooth sheets and corrugated sheets.
2. Cold-rolled grades are plates and strips made of steels St10–St45 with a thickness ranging from a few microns to 3 mm. Supplied from the manufacturer in rolls and sheets with cut edges.
3. Hot-rolled plates are made from grades St0–St5. Thin plates measuring 0.5–3.9 mm are also produced.
4. The expanded metal (PVL) variety is obtained by simultaneous operations: cuts are made on the sheet and it is lengthened - cells are formed. Due to this technology, the weight of flat products is reduced by 70% compared to a solid product.
5. The corrugated type provides the smooth sheet with anti-slip properties. It is made of ordinary carbon steel St0-St3; decorative items are often produced from stainless steel. Rhombic or lenticular protrusions make up 0.1–0.3 of the sheet thickness and are applied in the form of a pattern. The dimensions of the corrugations are 30x70 with intervals between them up to 20–30 mm.

Protrusions add weight to the sheet metal . A table of the mass of smooth rolled products and two types of corrugated ones is given below. Values ​​are indicated in fractions for plates: without protrusion, with lentil corrugations, rhombus:

The table shows the calculated mass based on the conditions: steel density 7.85 t/m3, dimensions and distances between protrusions are averaged. The height of the corrugation is 0.2 of the thickness of the smooth sheet.

Sheet metal weight in tables

Knowing the exact weight of sheet metal will allow you to avoid problems with an irresponsible supplier. It will help to preliminary estimate the amount of financial costs for a new project. Understand what load will put pressure on the metal structure being developed. As in any business, there are nuances here, so let’s not “go from side to side” and begin to study this issue.

General concepts

Before proceeding directly to calculating the weight, we need to understand what sheet metal is. A metal sheet is a rectangular profile, the thickness of which is disproportionately small compared to its length and width. Its parameters and dimensions are regulated by GOST 19903-2015 and GOST 19904-2015.

According to these state standards, sheet profiles are divided into the following categories:

• According to the production method.
• In terms of manufacturing accuracy.
• According to the level of surface flatness.
• By edge type.
• By type of material.

Let us now examine each point in more detail.

Production methods

Metal sheets are made by hot or cold rolling. These technologies involve rolling rollers onto a workpiece, as a result of which its surface is rolled out.

In general, the procedure for hot and cold rolling is similar. Only in the first case is the workpiece preheated to a temperature of 300-400 ºC. This is done in order to increase the malleability of the metal, which makes it possible to obtain sheets of greater thickness.

According to manufacturing accuracy

Depending on the purpose in production, the sheet can be manufactured with two degrees of accuracy: normal (B) and increased (A). High-precision rolled products have a more regular surface shape. For this reason, such a sheet has better strength and surface roughness.

Steel sheet: GOST

The production of sheet metal is regulated by the following standards:

1. GOST 19903-2015 defines the range of hot-rolled steel in sheets and rolls with a thickness of 1.2 to 25.0 mm.
2. GOST 19904-90 is used for cold-rolled steel with a thickness of 0.35 to 3.50 mm.
3. Depending on the types of metals used in the production of thick sheet metal: GOST 1577-93 for structural steel, GOST 4041-2017 for hot-rolled unalloyed structural steel, GOST R 58915-2020 for cryogenic metals.
4. For the manufacture of thin sheets, the following technical conditions are applied: GOST 3836-83 for electrical unalloyed steel, GOST 11268-76 for alloy steel;
5. Production of heat-resistant and heat-resistant rolled sheets, resistant to corrosion: GOST 24982-81 determines the general technical conditions, GOST 5582-75 is used for thin-sheet rolled products, GOST 7350-77 for thick-sheet rolled products.
6. GOST 8568-77 standardizes the production of sheets with rhombic or lenticular corrugation.
7. GOST 9234-74 regulates the range of sheet steel profiles.
8. Galvanized cold-rolled steel with polymer coating is produced in accordance with GOST 34180-2017 for hot zinc coating, and in accordance with GOST 34649-2020 for electrolytic galvanizing.

Previously, the production of expanded metal sheets was regulated by GOST 8706-78, which was cancelled. At the moment, technical conditions 36-26.11-5-89 are used, which contain requirements for the technical parameters and range of this type of rolled product.

Sheet weight

24.12.2017

Manufacturers often have to deal with the manufacture or processing of any structures made of sheet metal of different thicknesses.

In this case, you have to transport it. And when transporting, it is simply necessary to know the weight of this metal so as not to overload the lifting mechanisms (crane, forklift, car).

The fact is that when sheet metal lies in a stack, its weight can be taken as the mass of a solid monolith, because there are practically no gaps between the sheets. To determine the weight of galvanized sheets, you need to know the mass of one sheet, and here you can go in two ways.

The first, most common, is to read the transportation markings painted on the end of the pack in accordance with GOST No. 14192-77. It should contain all the main parameters of steel, including weight.

The second method has to be used when for some reason this inscription with the metal data is not visible. Then you have to use the weight tables for steel and rolled products according to GOST No. 13567-78.

• 1 Calculation of the weight of 1 m2 of sheet and rolled stock
• 2 Weight of rolled steel

Calculation of the weight of 1 m2 of sheet and rolled stock

For example, we have a galvanized sheet with an area of ​​S square meters. Using tabular data, we find out the weight of 1 m2 of rolled sheet with a thickness of 2,3,4,5,6,8,10 mm. By multiplying the value from the table by the area, we get the required sheet weight.

Calculation table for galvanized steel with polymer coating

If non-standard rolled sheets (of different thicknesses) are used, then you can safely use the formula:

M = L*W*T* (p) (7.85), where

T – rolled product thickness;

D – leaf length;

Р=7.85 – sheet steel data from the table;

W – product width.

When the weight of one steel sheet has been determined, it is necessary to calculate the weight of the entire bundle of rolled products, for which the result obtained is multiplied by the number of sheets in the package.

Rolled steel weight

And also to determine the weight of different sheets of hot-rolled steel st3sp/ps5, it is recommended to use another table:

For cold rolled steel the indicators will be completely different:

Cold rolled steel sheet 08ps/kp

And for galvanized steel, the regulatory data according to the GOST reference book are also different.

Galvanized steel 08ps/kp. Weight of 1m sheet

It must be remembered that the value from the table is the conditional weight of the steel sheet, since the actual weight of the steel sheet may differ slightly from the nominal value, depending on the grade of steel and the permissible rolling errors.

Metal weight calculation

The metal is widely used in various industries. When creating metal structures, it is necessary to first calculate two important indicators: strength and total weight.

The strength of the structure can be calculated using the methods of the theory of strength of materials. Weight is calculated taking into account the following characteristics:

• standard sample density (determined by physical characteristics);
• metal shape (according to the existing assortment - rolled sheets, channel, angle, pipe, etc.);
• geometric shape, part dimensions.

Metal weight calculation

The presence of various forms of metal products requires an individual approach when calculating the following parameters:

• the mass of the entire metal structure;
• required volume of metal.

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 7850 kg/m3);

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.

Sheet metal

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

It allows you to calculate the weight of products made of any material. It is obtained as the ratio of the density of the selected material to the density of steel. Next, to calculate the required parameter, it is enough to calculate such a parameter of a steel product of a given shape. The resulting result will be multiplied by the conversion factor for this material.

The coefficient is a dimensionless quantity. It has its own specific meanings for various metals and alloys. For example, aluminum has 0.34, copper - 1.14, and 1.12 is used for OTS5-5-5 bronze.

To calculate the weight of a sheet made of the specified bronze, it is necessary to obtain the parameter of the same sheet of steel, multiplying with a conversion factor.

Metal conversion factor

The same calculation method, the use of a conversion factor, can be fairly applied to non-metallic rectangular products. For example, to textolite with a coefficient of 0.18, organic glass - 0.15. The results obtained will satisfy the accuracy requirements.

What makes calculating the weight of metal more difficult?

A serious difference in the data obtained for calculating the mass of a steel product is the technology of its production. The difference between cold-rolled metal and hot-rolled metal can be quite significant. We are talking about the accuracy of geometric characteristics while maintaining density along the entire length of the product.

The use of continuous heating and subsequent cooling leads to such negative phenomena as oxidation and recrystallization. The unevenness of these processes causes a change in such a parameter as thickness.

Metal weight

The accuracy of calculations for cold-rolled and hot-rolled metal profiles will differ. The error caused by thickness instability requires obtaining some average value.

How to calculate the mass of a rectangular profile?

A rectangular profile is a parallelepiped with a given wall thickness. The wall thickness is specified in the technical documentation for a specific sample.

Square profile

Mass calculation can be done in two ways. In the first method, the cross-sectional area is calculated: for a sheet of a given thickness. Calculate the mass of a rectangular parallelepiped based on its external dimensions. Then the same calculations are made for a parallelepiped with internal dimensions. The difference between the two values ​​will be the desired characteristic.

In the second method, the weight of one wall of the structure is calculated. If the cross-section is square, multiply by four. If it is rectangular, the sizes of the smaller and larger walls will be calculated separately. Then multiply each value by two and add the results to get the final figure.

Square profile weight

To simplify the process, special tables have been developed.

Determining the weight of a round profile

Round metal products include solid rods, fittings, and pipes of various diameters. The approach to solving the problem remains the same. If the product is solid, it is necessary to calculate the volume, multiply by the density of the material. The volume of metal is calculated using known geometric formulas.

Round profile weight

If the round workpiece is hollow inside, you need to know the wall thickness. Next, you can use one of the methods applicable to calculate the value of rectangular rolled products. The only difference will be the calculated ratios for finding the volume.

How to find out the mass of a hexagonal profile?

Solid metal rods with a hexagonal cross-section are often used. The calculation method for such products remains the same. It is necessary to remember from the school geometry course how the volume of a regular hexagonal parallelepiped is calculated.

The task is greatly simplified if you know the size or number of such a rental. All numbers are given in a standardized table.

The hexagonal profile with the smallest number 10 weighs only 0.68 kg, the largest number 60 weighs 24.5 kg.

Hexagonal profile

It should be remembered that the use of simplified methods gives approximate results. They are used for express assessments. When developing design documentation in detail, more accurate indicators are used.

It allows you to calculate the weight of products made of any material. It is obtained as the ratio of the density of the selected material to the density of steel. Next, to calculate the required parameter, it is enough to calculate such a parameter of a steel product of a given shape. The resulting result will be multiplied by the conversion factor for this material.

The coefficient is a dimensionless quantity. It has its own specific meanings for various metals and alloys. For example, aluminum has 0.34, copper - 1.14, and 1.12 is used for OTS5-5-5 bronze.

To calculate the weight of a sheet made of the specified bronze, it is necessary to obtain the parameter of the same sheet of steel, multiplying with a conversion factor.

Metal conversion factor

The same calculation method, the use of a conversion factor, can be fairly applied to non-metallic rectangular products. For example, to textolite with a coefficient of 0.18, organic glass - 0.15. The results obtained will satisfy the accuracy requirements.

Price of sheet 40 mm

The advertisement “ selling 40 mm sheet metal ” is often found on the Internet. This is understandable: rolled sheet metal is in great demand. The price of any sheet of metal depends on its size, the steel from which it is made, and the accuracy of its dimensions. Most often, the price for hot-rolled sheets is indicated in rubles per ton of weight. On this basis, the cost of the entire sheet is calculated.
