Metal calculator
With relative accuracy, you can calculate the weight of rolled metal and the amount of steel reinforcement. By entering dimensions and lengths, you can calculate the weight of the products. The calculator works in online mode for quick weight calculation, for this you need:
- select the required steel grade;
- select rental category;
- Enter the dimensions and dimensions of the sides.
Our resource specialists periodically update the steel grade for accurate and up-to-date calculations of products. In the calculation process, the specific gravity of rolled metal (calculator table) steel and size (metal thickness, sheet width, diameter of pipe wall, channel, etc.) are used.
Sometimes when the grade of steel from which it is made is unknown, in this case you can use universal grades such as St10 and St20. If you still have suspicions about the raw materials, you can perform a chemical test. metal analysis.
Rolled metal weight table
The calculation formula determines the weight of 1 mm of rolled steel multiplied by the length (if the weight is calculated based on the length value). In the case when the initial data is weight and a table of rolled metal from tons to meters is required, the cross-sectional area of the rolled metal multiplied by the specific gravity is first determined, after which the weight is divided by the value obtained by multiplication and we obtain the required length by weight.
It should be noted that the weight table of rolled metal depends on the temperature of the calculated rolled product, so, at different steel temperatures, its density changes significantly. Based on this, the calculation uses a universal steel temperature of 20 °C. For non-ferrous metal products, other temperature values may be used, please pay attention to this.
In real life, the sizes of rolled products produced, especially in large-volume batches, may differ significantly from the calculated values. This is due to the fact that the table of mass of rolled metal does not take into account deviations from the exact geometric parameters of the product, which necessarily exist, especially for large volumes.

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
What is a conversion factor?
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
The calculations are based on a formula for calculating the volume of a regular hexagonal prism. Having calculated this volume, it is multiplied by the density of the metal. A mass of hexagonal product is obtained.
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.
Finding the parameter of a metal pipe of any diameter is carried out similarly to the method for a round profile. Calculate the difference in the areas of two circles. The first has the outer radius of the pipe. The second has the inner radius of the pipe.
The resulting difference is multiplied by the length of the pipe, calculating the volume of metal. Multiplying by the density of steel, the mass of a pipe of a given length is found. Operations with non-ferrous metal products are simplified through the use of a conversion factor.
Pipe weight
When working with ready-made tables, you should find data for a 1 m bar with a radius equal to the outer diameter. Calculate the diameter of the rod, which is equal to the internal diameter. Subtract the smaller value from the larger value to get the desired result. It should be multiplied by the length of the sample.
How to calculate the mass of an angle, channel, I-beam
The parameter is calculated using data on the width of the shelf and the thickness of the metal. The product is considered as half of a rectangular profile.
There are ready-made calculation tables for the entire range of rolled metal products.
However, corners from different manufacturers have real weight characteristics that differ from the tabular data. They deliberately reduce the thickness of the shelf. They are motivated by the desire to reduce the cost of products. The parameter difference differs significantly from the parameters provided by GOST.
Weight of anglesWeight of channelWeight of I-beams
The weight characteristics of the channel and I-beams are determined according to the tables. This is caused by the difficulties of calculating the volume of complex geometric shapes.

What determines the weight of a steel sheet and how to determine it
Nowadays, steel is in special demand as a durable and reliable building material. It is used in the form of blanks for mechanical engineering, construction work and other industries. The use of steel sheets is also popular. The latter differ in area, thickness, rolling strength, rolling method, edge character and flatness. The scope of application of the material and its mass, and, accordingly, the price, depend on these parameters.
Characteristics of steel
To determine the mass of a steel sheet, you can use special online calculators, which are presented on many websites. If you don’t have them at hand, a table will come to the rescue.
The thickness of the steel can be:
- Thin - thickness does not exceed 3.99 mm. This is usually a cold-rolled metal.
- Thick - thickness reaches 160 mm. These most often include hot-rolled steel.
By the nature of the edge:
- With cut edge;
- With uncut edge.
By flatness:
- Particularly high flatness or PO;
- High flatness or PV;
- Improved flatness or PU;
- Normal flatness or PN.
By rolling strength:
- A - increased accuracy;
- B - normal accuracy.
By production method:
- Cold rolled;
- Hot rolled - hot metal is rolled out using a special press to the desired thickness.
Additionally, galvanized and corrugated (rhombic and lentil) options are available. Depending on the selected parameters, the weight of the steel will also fluctuate.
General formula
To find the mass, the general formula is usually used:
Weight = surface area (length x width) x weight per kilogram per 1 square meter. meter,
where the weight is determined from the table, based on the thickness and rolling method. The length and width should be converted to meters.
If you don’t have a table at hand, you can use the following formula. It is suitable for determining the weight of sheets obtained by hot-rolled and cold-rolled methods.
Weight = length x width x thickness x 7.85,
where 7.85 kg/dm3 is the density of steel 1 mm thick. Length and width should be in meters, thickness - in millimeters.
Cold rolled steel
Depending on the parameters, the weight of the steel sheet can vary from 5.5 kg to 47 kg, with the weight of steel per square meter from 2.75 kg to 23.5 kg. The table below will indicate the weight for a steel sheet 1 meter wide and 2 meters long.
Material parameters range from 0.35 mm to 1 mm, pitch - 0.05 mm
Material parameters range from 1.2 mm to 2 mm, pitch - 0.1 mm
Material parameters range from 2.2 mm to 3.5 mm
Hot rolled steel
When hot rolled, the thickness of the steel sheet ranges from 1.5 mm to 160 mm. The weight ranges from 12 kg to 1256 kg.
Material parameters range from 1.5 mm to 3.5 mm, pitch - 0.5 mm
Material parameters range from 4 mm to 10 mm, pitch - 1 mm
Material parameters range from 10 mm to 40 mm
Material parameters range from 45 mm to 160 mm
Other classes of steel sheets
When calculating the weight of steel, it is important to consider the differences between hot-rolled and cold-rolled steel, zinc-coated sheets and corrugated versions. Due to the peculiarities of their creation, their weight and parameters differ significantly. For example, the thickness of galvanized metal consists of the metal itself and the coating on top and bottom. In the table they are already included in the specified parameters.
The parameters of galvanized material range from 0.35 mm to 1 mm

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.

How to calculate the mass of a sheet of metal - Metalworker's Handbook
Galvanized steel sheet can be used in different ways in agriculture, industry, construction and many other areas of human activity.
And in order not to encounter scammers who will try to sell you a low-quality metal product, you need to know all the parameters that determine real galvanized sheet steel.
For example, transport marking of packages must be applied according to GOST No. 14192-77 with dark-colored dyes on the end of the surface of the pack and on the side of the surface of the roll. The marking must contain primary and secondary inscriptions that carry information.
Sheet according to GOST No. 14918-80
The standard conditions apply to steel in the form of sheets and coils that are hot-dip galvanized in permanent galvanizing units.
The technical degree coefficients, which are established by standard norms, must be in accordance with the requirements of the first two quality categories.
Galvanized sheet steel is divided into:
1. By purpose:
- for types for cold stamping - X W,
- for cold profiling - X P,
- for painting - P K,
- general use - OH;
2. According to the ability to draw (steel category X W):
- conventional hood - H,
- deep drawing - G,
- very deep drawing - V G;
3. According to the uniform thickness of the special zinc coating:
- with normal thickness variation - HP,
- with reduced thickness variation - U P;
4. By mutual agreement of the customer and the manufacturer, steel can be manufactured:
- with zinc stains on the surface - KP,
- without zinc stain on the surface - MT;
5. Depending on the thickness of the special coating, galvanized steel is divided into three classes:
- elevated,
- first,
- second.
Galvanized steel is produced in widths from 710mm to 1800mm, thickness from 0.5mm to 2.5mm from cold rolled steel.
How to calculate the weight of galvanized steel sheets?
M=M1+M2, where M is the final weight of the sheet (kg), M1 is the weight of iron (kg), M2 is the weight of zinc (kg).
In this case, M1=T1 x l1 x H1 x P1,
where T1 is the thickness of the iron sheet (mm). When calculating, it is important to take into account that the thickness of the iron is 0.05 mm lower than the finished product for class 1 zinc special coating and 0.03 mm less for class 2; l1 - length of sheet iron (m); H1 - width of iron sheet (m); P1 is an indicator of iron density (7.85 t/m3).
M2=T2 x l2 x H2 x P2,
where, T2 is the thickness of the galvanized layer (depending on the category, where the thickness of the 1st category is 0.0381 mm, and the second is 0.0216 mm); l2 - length of special coating (m); H2 - width of special coating (m); P2 is an indicator of zinc density (7.13 t/m3).
Thanks to the formula, it is possible to make calculations before purchasing. This will allow you not to be deceived and to accurately calculate the required amount of material.
There are also tables that already have calculations and ready-made results. Therefore, in some cases, avoiding calculations, you can refer to the following tables:

All rolled products, depending on their shape, can be divided into four main groups:
a) grade steel;
b) sheet steel;
c) pipes;
d) special types of rental.
Rolled sheets of steel and non-ferrous metals are used in various industries and construction. In this regard, sheet steel, for example, is divided into automotive, transformer, roofing sheet, etc.
The production of sheet steel with tin, zinc, aluminum and plastic coatings, polymer coating, as well as flat, smooth and profiled: corrugated sheets, expanded metal, perforated, is expanding.
Sheet steel is divided into groups depending on the thickness of the section. Sheets more than 4 mm are classified as thick sheet steel, and sheets less than 4 mm are classified as thin sheet metal. In this case, there are the following types of sheet steel: shipbuilding, boiler, electrical, tin, acid- and heat-resistant, armor, etc.
The qualitative characteristics of flat products are determined by mechanical properties, chemical composition, molecular structure, use for further processing and, finally, smelting method. When producing rolled sheets, the thickness may have plus or minus tolerances, which entails changes in the actual weight of a square meter of sheet.
The larger the dimensional tolerance for a given flat product (the difference between the maximum and minimum dimensions of the flat product), the greater will be the difference between the theoretical weight of the sheet steel and the actual weight.
Hot rolled sheet of ordinary quality is made from thin sheet steel (thickness 0.5 mm - 3.9 mm) GOST 16523-89 and thick sheet steel (thickness 4 mm - 160 mm) GOST 14637-89. Flat sheet metal is widely used by the company "Skhid-budkonstruktsiya" in the production of steel containers.
The assortment of steel sheet corresponds to GOST 19903-74, the chemical composition of steel corresponds to GOST 380-88. The assortment for cold-rolled sheet steel provides for the supply of sheets with a width of 600–1400 mm and a thickness of 0.2–3.9 mm. Sheet length 1200-3500 mm. Assortment standards for cold-rolled steel coils provide for the supply of strips with a width of 200-2300 mm and a thickness of 0.2-4 mm.
The current standards stipulate specific gravity, tolerances for sheet thickness and thickness variations, depending on the dimensions of the sheet or tape and delivery conditions. The standard includes standards for tensile strength and elongation. The permissible warpage per 1 linear line is also specified. m along the length and width of the sheet and control for decarbonization.
In some cases, the technical conditions stipulate tighter tolerances than in the standards.
Rolled sheets are divided into cold-rolled and hot-rolled
Cold-rolled sheet with a thickness of 1 mm, 1.2 mm, 1.5 mm, 2 mm, 3 mm, available from steel grades 08KP, 3SP/PS.
Hot rolled sheet thickness 2mm, 2.5mm, 3mm, sheet 4, 5, 6mm, 8-10mm, 12mm, 14-16mm, 18mm, 20-32mm, 35mm, 36mm, 40 mm, 45 mm, 50 mm, 60 mm, 65 mm, 70 mm, 80 mm, 90 mm, 103 mm, available in grade st 3SP/PS, steel 09G2S-12; thickness from 4 mm to 50 mm steel grade 45.
Galvanized sheet thickness 0.5 mm, 0.55 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm - galvanized iron + polymer coating.
Cold rolling has two great advantages over hot rolling: firstly, it allows the production of sheets and strips with a thickness of less than 0.8-1 mm, down to several microns, which is unattainable by hot rolling; secondly, it ensures products of higher quality in all respects - dimensional accuracy, surface finish, physical and mechanical properties. These advantages of cold rolling have led to its widespread use in both ferrous and non-ferrous metallurgy.
In the production of hot-rolled steel sheet, the metal is first heated and then deformed using special rolling mills by rolling. Cold rolling ensures uniform sheet thickness and also improves its properties by hardening the surface.
Hardening is formed as a result of changes in the structure of the steel sheet . sheet, metal grains are stretched and oriented along the direction of plastic flow of the metal with axes of greatest strength. A metal sheet acquires different properties along and across, i.e.
along the length and width of the steel strip . At large degrees of plastic deformation, all metal grains are almost identically oriented in the structure of rolled steel sheets . Plastic deformation during rolling of a steel sheet causes hardening of the metal - cold hardening or cold hardening.
In this regard, to restore plastic properties it is necessary to carry out annealing.
Hot-rolled and cold-rolled sheets are used in mechanical engineering, metal structures, construction, mining and other industries. The actual scope of application determines the requirements for sheet metal. For the manufacture of products by stamping, sheet metal is used: cold-rolled, hot-rolled, cold-rolled coil, galvanized steel in coils, strip metal.
This table is used when calculating the mass of rolled sheets based on the specific gravity of a square meter of sheet metal.

Calculation of how much 1m2 of steel sheet weighs using the formula
How to calculate the weight of sheet metal by area?
Using a simple calculator you can easily calculate the weight of a steel sheet without having a table of thickness and weight of 1m2.
The weight of a sheet of metal is calculated using a regular calculator using the formula:
P = H*B*L* 7.85
where
P- theoretical weight, kg
L is the length of the metal sheet in linear meters, m;
H—sheet thickness, mm;
B—width of rolled sheets, m;
7.85 kg/dm3 - density of black steel, 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 steel sheet, you can easily calculate how many sheets are in a ton or pack of a certain mass.
To quickly calculate the weight of rolled sheets, use the “Metal Calculator” in the “Metal Assortment” section of the website.
The sheet weight calculator calculates the weight for different grades of steel, which is important if you need to calculate the weight of a stainless steel sheet or made of non-ferrous metal.
The sheet metal calculator calculates the weight based on the dimensions of the workpiece and thickness in mm, and the dimensions of the steel sheet (based on the total weight of the package and the thickness of the rolled sheet).
The assortment of sheet steel is needed primarily by suppliers for metal purchases to calculate the weight of rolled metal. If in the process of work the question often arises about how to find out the weight of sheet metal, but there is no assortment of rolled metal at hand, the best way to solve this problem is to calculate the weight of the sheet using the above formula on a calculator.

How to calculate the weight of metal - formulas and recommendations
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 to find out the area of a sheet (of any shape - square, rectangle, parallelepiped, trapezoid, rhombus, etc.) - every person who has 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.
How to establish the mass of a structure of particularly complex shape
This problem can be solved in two ways. According to the first of them, the value of the so-called fill factor is established (the method is used for dimensional units, the disassembly of which is either difficult or completely impossible). For example, for sliders of crank machines, the fill factor is taken to be 0.30.35. Then the mass of node G is calculated under the assumption that it is solid, and then the result is multiplied by the fill factor.
Nistratov’s empirical formula gives approximately the same accuracy:
, where P is the nominal press force in tons.
In an original way, you can install a lot of small one-piece structures according to the volume of water they displace. To do this, water is poured into a tared container to the brim. Place the container in another with a much larger volume, and then place this structure in the first container. The volume of water displaced by it is weighed. This volume will be equal to the volume of the structure.

Formula for calculating the mass of metal
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.
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.
How to find out the mass of a pipe
Finding the parameter of a metal pipe of any diameter is carried out similarly to the method for a round profile. Calculate the difference in the areas of two circles. The first has the outer radius of the pipe. The second has the inner radius of the pipe.
The resulting difference is multiplied by the length of the pipe, calculating the volume of metal. Multiplying by the density of steel, the mass of a pipe of a given length is found. Operations with non-ferrous metal products are simplified through the use of a conversion factor.
When working with ready-made tables, you should find data for a 1 m bar with a radius equal to the outer diameter. Calculate the diameter of the rod, which is equal to the internal diameter. Subtract the smaller value from the larger value to get the desired result. It should be multiplied by the length of the sample.
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.

Sheet metal weight calculator
Rolled metal is a separate branch of metallurgy, the products of which are widely used in various sectors of construction, mechanical engineering, aviation and shipbuilding.
Below is a sheet metal calculator that allows you to calculate the weight of one or more sheets of various sizes. The result obtained will allow you to navigate and decide on the delivery method if products are purchased in large volumes.
[CP_CALCULATED_FIELDS id=”29″]
The calculator used a formula based on the density of the material and its volume. The density values of various metals are already contained in the online program database and were taken in accordance with GOST.
To carry out calculations, you need to select the type and grade of the metal itself from the proposed options in the drop-down block. These metals are most often used in the rolling industry.
Next, you will need to set the product parameters in millimeters. Then, based on the entered data, the calculator will calculate the weight of the sheet metal. The result will be rounded to the nearest whole number and displayed in the corresponding field.
Manufacturing method and classification
Storage of products after rolling and cutting
The production of rolled sheets occurs by rolling a metal “blank” or cast billet through a rolling mill. Depending on the technology, there are two methods for producing rolled products:
Hot rolling technology is more universal and is used for the manufacture of products of any thickness. Cold rolling is typically used to produce sheets up to 5 mm thick and has higher precision.
Classification of sheet products can be made based on several parameters: thickness, manufacturing method, material.
The thickness of the rolled products differs into thin and thick sheets. The thickness depends on the required alloy and customer preferences. For example, alloys based on copper or aluminum make it possible to obtain sheets up to 0.1 mm thick.
Rolled products are regularly used both in construction and in some heavy industries. For example, alloys of aluminum and other light metals are used to create the skin of aircraft, small ships and cars.
Thin-layer steel sheets are often used for the construction and cladding of prefabricated industrial premises.
Formulas for manual calculations
Formulas for calculating the mass of metal in sheets of any shape and thickness
In addition to the online calculator, calculation operations can be performed manually. To do this, use the following formula: m = p * V, where m is the mass of the product, p is its density, and V is the volume of the sheet.
The volume of a sheet or any other rectangular or square workpiece is calculated by the formula: V = S x h, where S is the area of the product, and h is its thickness.
As an example, let's calculate the weight for AK6 aluminum sheet. Sheet length – 5 m, width – 2 m, thickness – 4 mm. The density of this metal at a temperature of 20 °C is 2750 kg/m3.
Based on these parameters, the calculations will look like this:
- V = (5 * 2) * 0.004 = 0.04 m3.
- m – 2750 * 0.04 = 110 kg.
To check these results, you can use a calculator, which will show approximately the same values. Remember that when entering data, all parameters should be specified in the appropriate dimension.
If an error occurs or a significant discrepancy in the results, please inform the administration via the feedback form. We will try to quickly fix this problem.
