How to calculate the area of a sheet 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.
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
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.
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.
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.
DIY metal belt grinding machine
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.

Steel sheet weight
Rolled metal calculator
Today, rolled sheets are used in many areas of the national and industrial economy. It is quite natural that when purchasing this material, you need to navigate its many characteristics, including weight, which will be discussed in this article. So let's get started.
How to calculate the weight of galvanized sheet?
The main difference between galvanized sheet and other types of sheet steel is the presence of a zinc coating applied during manufacturing. This treatment allows you to protect the steel sheet from the negative effects of the environment and avoid the appearance of rust.
The weight of 1 m2 of steel sheet in this case is the product of the length, width, thickness and density of the galvanized sheet. It is worth noting that the density of zinc is slightly lower than the density of steel and is equal to 7130 kilograms per cubic meter of metal.
Thus, the weight of galvanized sheet m2 depends on the thickness of the zinc coating can be calculated as follows.
Sheet mass = m1*a*b*7.85+m2*a*b*7.13, where:
a – sheet length;
b—sheet width;
m1 – mass of the steel component of the sheet;
m1 – mass of the zinc component of the sheet.
The values of m1 and m2 can be taken from specialized tables.
How to calculate the weight of hot rolled sheet?
Unlike galvanized sheets, hot-rolled sheets are manufactured using a different technology, namely hot rolling. Distinctive features of this rolled metal are its smooth surface and high strength.
You can calculate the weight of such a sheet using specialized tables or using a rolled metal calculator, which can be found here.
How to calculate the weight of stainless steel?
In accordance with GOST, stainless steel can be produced either by hot rolling or cold rolling. Moreover, depending on the processing method, there are:
- cold-worked sheets;
- semi-hardened sheets;
- heat treated sheets.
Stainless steel is made from a number of different steels, differing in their characteristics and, accordingly, weight.
Thus, in order to calculate the weight of a specific stainless steel sheet, again, it is better to use tables.
As you can see, there is nothing complicated in calculating the weight of a steel sheet, both regular and galvanized, and anyone can calculate it.

Metal weight, conversion calculator ton-meters of rolled metal
When you don’t have a reference book at hand, but you need to make the appropriate calculations of the mass of metal according to the length, diameter, and cross-sectional dimensions of steel blanks, we will teach you how to do this.
If you only have a tape measure with you for measuring MM, CM, M, and a calculator on your Android phone, you can do all the calculations yourself, and simple geometric formulas will not be an obstacle to calculating the weight yourself. In tonnage calculations, the base value will be the average steel density of 7,850 kg/m3 (specific gravity) multiplied by the volume of the metal structure.
Everyone knows this simple formula for calculating mass through density and volume from the 7th grade physics textbook. You can learn how to correctly calculate the volume of metal by remembering school geometry (several formulas are presented in the table below). For example, for rolled sheets, the surface area is calculated and multiplied by the sheet thickness.
It is difficult to obtain accurate results with such an arsenal, but it is quite possible to approximately determine the weight of some metal products. When you have access to the Internet, then calculating the mass of rolled metal products will not be difficult. The metal conversion calculator can be used online or downloaded to your computer.
Calculation of rolled metal weight
The universal metal steel weight calculator allows you to quickly and accurately calculate the weight of rolled metal by size (diameter according to GOST, DSTU, length of footage, metal area, volume), i.e. learn how to convert linear meters into kilograms of steel (m - kg, m - ton). The weight of a rolled steel profile is determined by the size and shape of its cross section, and for this you do not need to know how much a meter of rolled metal weighs.
Our long rolled metal calculator calculates the following types of rolled steel according to GOST: round, square, strip, sheet and shaped parts: metal pancakes, steel balls and other complex shapes of objects.
Here you can find out the weight of an object, calculate the mass of a steel sheet, plate, circle, steel rod, cylinder, rod, steel strip, wire, calculate the mass of a metal angle, steel pipe, channel, beam and determine how many meters are in a ton of rolled steel.
How to determine the weight of metal by size?
Unlike the Metallurgical Calculator program, here you do not need to download a program for determining the weight of metal according to GOST. Calculation of weight based on the dimensions of the workpiece is carried out automatically online.
Conversion of mass (kg, tons) into length (linear meters) or conversion of metal weight into area (m2 for sheet steel) is carried out synchronously in real time, and there is no need to look for conversion tables of specific gravity to convert meters to tons of rolled metal.
And, if you know how much a meter of rolled metal weighs, then you can independently calculate the price per meter of rolled metal using a simple calculator by multiplying the weight of a linear meter by the cost of a kg of steel. Or vice versa, convert the price per meter into the price per ton of metal.

The formula for calculating the weight of metal by size uses the theoretical weight of rolled metal according to GOST (specific gravity of steel or conversion factor in kg), the dimensions of the profile section and the length of rolled metal (to calculate the volume of metal). The product of metal density and volume gives us the required weight (kilograms, tons) of rolled products of a given length
(linear meters).
Rules for calculating metal by weight and length
1. Select the type of metal: “Steel” is the default (suitable for calculating both black and stainless steel). The electronic calculator can calculate rolled copper, aluminum and other non-ferrous metals. 2. Select a steel grade according to GOST (for example AISI 304/304L, AISI 316/316L) or non-ferrous metal (duralumin, lead, copper, brass, gold). 3.
On the left side of the metal calculator, select the type of rolled metal (profile pipe, metal sheet, steel angle, etc.). By default, there is a pipe metal calculator (round seamless pipes, VGP pipes, electric welded pipes). 4. We indicate the parameters of the rolled steel in millimeters (pipe diameter, channel size, beam height, wall thickness, angle flange size, etc.
) 5. We indicate the length of the rolled metal (to calculate the weight of the metal by size, i.e., converting from meters to kilograms, meters to tons) or the mass of the rolled metal (to calculate the length of the profile metal, i.e., converting the metal from kg to meters, tons in square meters).
6.
Click on the “Calculate” button on the “Metal calculator according to GOST” and get the weight of the product in kilograms or the length of the metal profile in meters (when translated vice versa).
Every Internet user has moments when it is necessary to calculate some nuances of the work and determine how much metal is needed to make a metal product, calculate its price, knowing the total weight.
For example, convert the mass of metal into length (area m2), convert meters into tons of rolled metal, when you need to calculate the mass of metal structures, find the mass of a steel part, or convert the mass to the surface area of the paint.
And it doesn’t matter whether you are going to build a house from metal structures or invest money in metal, you will need to calculate the cost of rolled metal online, then our directory website will come to your aid. All you need to do is select the appropriate brand of rolled metal and enter the required parameter values, and our online calculator will solve for you any problem of your misfortunes or, conversely, joys.
How to find mass without scales, calculate weight using the formula?
For example, we need to find the weight of metal structures, calculate the mass of a metal truss, an iron door, a sheet metal gate, a stainless barrel or another non-ferrous metal product.
To do this, the metal structure is divided into its component elements and the weight of the metal is calculated using the formula (see examples of formulas for the area and volume of simple bodies) or using a calculator program. The mass of the metal structure consists of the weight of all structural elements and the mass of deposited metal (1.5%).
Having determined the weight of the product and knowing the price per ton of production, you can calculate the cost of a custom-made metal product yourself.
Converting metal from meters to tons is necessary when purchasing rolled products. The sale of metal products in Ukraine is an increasingly popular service every year; today you can purchase rolled metal products via the Internet.
But purchasing products from metallurgical plants is not always easy in terms of their technical data and other characteristics.

Weight of galvanized steel sheet
> Useful tips > Weight of galvanized sheet steel
To build a cottage or house, a specialist needs to solve a large number of different issues. To do this, he considers all stages of construction, prepares calculations of upcoming income and expenses. But it is difficult to take into account how much material will be needed. It is necessary to resort to accurate calculations.
How to determine the weight of steel?
Galvanized steel sheets are widely used in manufacturing, construction, economic activity and rural industry. In order not to cooperate with frivolous enterprises and factories offering this product, you need to take into account the weight of the steel. It is calculated using simple general mathematical operations.
The weight of galvanized sheet steel (T) is calculated by adding the mass of iron (T1) with the mass of zinc (T2)
T=T1+T2
Where, T1= r1*k1*w1*q1?
- r1 - thickness of the iron sheet
To calculate it, you need to consider the thickness of the metal, since the finished product has a zinc surface of level 1 that is 0.05 mm smaller, and for level 2 by 0.03 mm.
- k1 – sheet length
- w1 – sheet width
- q1 – density of iron, coefficient is 7.85 t/m3
T2=r2*k2*w2*q2
- r2 – thickness of zinc coating. It depends on the classes: the first is 0.0381mm, and the second is 0.0216mm
- k2 – layer length (m)
- w2 – layer width (m)
- q2 – zinc density, coefficient is 7.13 t/m3
Let's consider a sample of calculating the weight of a galvanized sheet with the usual data 1000X2000mm, first class and thickness equal to 0.5mm
Substitutes numbers into the formula and calculates.
M= 0.45*1*2*7.85+0.0381*1*2*7.13=7.608 kg
Using such calculations, it is possible to calculate the weight of one galvanized sheet and the entire series. These calculations make it possible to check organizations and enterprises that sell goods and isolate them from unscrupulous and not serious entrepreneurs.
Similar formulas are used not only to calculate the weight of steel, but also the density of bricks and the volume of foam.

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:

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.

Online metal calculator - weight calculation
Metal calculator is a convenient solution for determining the weight of rolled metal. Before purchasing such products, you must first find out which car is suitable for transportation. It is the total weight of the rolled metal that will influence the tonnage of the car or other vehicle for transportation.
A natural question arises: how to calculate the weight of the required number of products? Previously, calculating mass required a lot of effort even from experienced specialists. After all, carrying out various calculations was impossible without knowledge of the theoretical basis of different metals, formulas for calculating volume, forms of rolled metal, and much more. It is this labor-intensive process that prompted the search for effective and quick methods.
Today, instead of various tables, formulas and lengthy calculations, the most convenient way is used - an online calculator.
Metal weight, length and cost calculator
How to use the calculator?
The standard metal calculator on our website will allow you to accurately calculate the weight of the products you are interested in. Our clients have the opportunity to calculate the weight of products by specifying specific lengths and dimensions. The calculator operates online and is also available for download. To calculate the mass of products, you just need to select:
- the steel grade of interest;
- rolled metal assortment;
And then - indicate the dimensions of the sides. This application makes it possible to determine the weight of the product of almost all existing grades of steel: black, non-ferrous and stainless. The online calculator will allow you to determine the mass of products made from alloys of copper, bronze, aluminum and others. Our clients will be able to calculate the weight of circle, rod, strip, sheet metal, plate, beams, round and profile pipe.
A convenient widget demonstrates what specific characteristics are required for further calculations. Each type of rolled metal product has an addition in the form of a schematic image of its cut with each shelf, face, etc. displayed in the form of letters. The unit of measurement for dimensions is the millimeter, the weight is calculated in kilograms accurate to the second decimal place.
How is product weight calculated?
The purpose of the online calculator in this section is to make it as easy as possible for you to determine the mass of the metal you are purchasing. The calculation formula reveals the weight of 1 mm of rolled steel multiplied by the length (when calculating the weight in accordance with the length value). If weight is used as the initial data, and a table of rolled metal from tons to meters is also needed, first of all it is necessary to determine the cross-sectional area of the rolled product, which was multiplied by the specific gravity.
Next, the weight should be divided by the amount determined by the multiplication method - this way you will get the length of interest by weight. It should be taken into account that the table of weight of non-ferrous metal is influenced by the temperature indicator of the calculated product, since at different temperature values steel has different densities. Accordingly, the calculation takes into account the standard steel temperature of 20 degrees Celsius.
For non-ferrous metal products, other temperature values are used; it is necessary to keep this fact in mind.
In reality, product sizes, especially in large volumes, may not correspond to the stated values. This is explained by the fact that the weight table does not take into account deviations from certain geometric characteristics of products, which actually occur in reality.

Sheet Metal Weight Chart: How to Calculate the Specific Gravity of Aluminum
Weight is an important and integral characteristic of any metal product. When selling or buying, weighing is most often used to determine it, but in everyday life, accounting and many other cases, determining the mass in this way is not always possible.
The thing is that the sheets have a large area, so finding the right scales is not easy. For example, for most metal sheets, the standard dimensions are 1.5 x 6 m.
To find out, a sheet metal weight table is used or calculations are made using formulas.
Determination methods
Methods for determining mass can be divided according to calculation methods:
- According to the specific gravity of sheet metal from tables in GOST or specialized reference books.
- Independent calculation of the specific gravity of 1 m² of metal sheet.
- Online calculators on specialized sites. They are also called methods for determining theoretical weight.
It is impossible to determine an absolutely accurate weight, because any rolled metal is produced with certain tolerances. Maximum deviations for each product can be found in GOSTs or manufacturer's specifications. Another point that may affect the determination of the theoretical mass is the specific gravity of 1 m³ of metal used for calculations.
For example, the task is to calculate how much a sheet of aluminum weighs. To do this, you need to use the table of the specific gravity of sheet aluminum. It states that it is equal to 2850 kg per 1 cubic meter. m.
This is the density of the most common aluminum alloys V95, V95−2, V95−1, but there are many grades of aluminum, and their density also varies slightly.
You can find out how much aluminum or any other metal weighs (meaning specific) in a particular product from the manufacturer’s quality certificate. The difference between the theoretical and actual mass is so small that it can be easily ignored.
Calculation using tables
This method of determining theoretical weight has become widespread. When using it, a minimum of calculations is required, which minimizes the possibility of errors in mathematical calculations. In the tables, in addition to data on the weight of 1 m² of metal sheets, there is information on the weight of 1 linear meter. m for the most common standard sizes of rolled metal.
To calculate the weight of a metal sheet, you need to take from the table the weight of 1 m² of sheet of the required thickness and steel grade and multiply it by the width and length (m=PxLxH). If the sheet is of a standard size, you can take the weight value of 1 linear meter from the table. m of the corresponding thickness, width and steel grade, multiply it by the length (m=PxL). For some grades of steel it is not available or it is difficult to find tabular values for the weight of 1 m² of sheet, but there is always a conversion factor.
The coefficient is the number by which the base density value must be multiplied to obtain the value for a particular steel or alloy. The basic value of steel density is 7850 kg per 1 m³. For example, there is a bronze sheet of grade OTSS 5−5−5 1 m wide, 2 m long and 2 mm thick. The conversion factor for bronze OTS 5−5−5 is 1.12. We convert the thickness in mm to meters (2 mm = 0.002 m). Thus, the mass of the sheet is 7850 x 1.12 x 1 x 2 x 0.002 = 35.168 kg.
Do-It-Yourself Computing
When you don’t have GOST or specialized reference books at hand, you can independently calculate the specific gravity of 1 m² of sheet. It's easier than it seems at first glance. If you calculate the mass of 10 aluminum sheets 2 m long, 1.5 wide and 3 mm thick. The algorithm of actions is as follows:
- Take from reference books the density value of the material you are looking for or the conversion factor. For aluminum the density is 2850 kg/m³. (If we take the conversion factor, we get the same value 7850x0.363 = 2850 kg/m³).
- The specific gravity of 1 m² of sheet is calculated: 2850x1x1x0.003 = 8.55 kg.
- The area of one sheet is determined by the formula S=LxH, where L is length, H is width. S=2x1.5=3 m².
- The mass of 1 sheet is calculated as 3x8.55 = 26.65 kg.
Weight of 10 sheets: 26.65x10=265.5 kg. You can calculate the mass without intermediate calculation of the specific gravity of 1 m² of sheet, but after counting once, the method can be used in the same way as the tabular value.
Using online calculators
When you have access to the Internet, you can calculate the weight of any rolled metal in a matter of seconds. A smartphone with Internet access or a special program is enough. The calculation algorithm using such calculators is extremely simple.
First of all, the type of rolled metal and the grade of steel from which it is made are selected. Fill in all the necessary fields for calculation (thickness, length, width) and press the button to perform the calculation.
The main thing with this method is to correctly indicate all the data in the required units of measurement.

Calculation of sheet steel weight
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.

Weight of galvanized sheet - calculation rules, characteristics and dimensions
Galvanized steel sheet has a wide range of applications, and this applies to both industrial and domestic construction work. Galvanization can withstand considerable load and deformation. They are very easy to stamp, roll, stretch and bend.
Galvanized steel sheets are used in the construction of buildings for a wide variety of purposes; in addition, they are used for cladding walls, constructing ventilated facades, and producing additional structural elements.
They are ideal for roofing and decorative elements. They are often used even in the manufacture of household appliances.
Due to its low weight, the material does not place serious additional load on the foundation and walls. In addition, this type of material can be used in work where the most serious requirements for product quality are imposed.
Material characteristics
Galvanized sheet is produced by rolling steel with the addition of zinc, the latter covering the product on all sides. Due to this, the development of corrosion processes formed during the interaction of iron with oxygen contained in the air is prevented.
On sale you can find material that is coated with zinc on only one side. This is required in order to subsequently send the sheets for further processing, which may include the following:
- Hood;
- Bending;
- cutting;
- Profiling and so on.
On sale you can find several types of galvanized steel sheets - corrugated, smooth, made in the form of corrugated sheets.
During the processing of the product, all its useful technical characteristics are preserved:
- Mechanical strength;
- Flexibility;
- Resistance to corrosion processes;
- Ability to post-process.
To obtain such material, high-quality sheet steel obtained through the cold rolling process is used. Zinc is applied using galvanic technology or hot-dip galvanizing.
The galvanic application method consumes a significantly greater amount of energy compared to hot-dip galvanizing. As a result, it is much more efficient to pass a sheet of steel through molten zinc. The coating can be uniform or patterned. It is worth noting that zinc coating can have different colors and textures. The service life of the material is several decades.
Zinc is applied using galvanic technology or hot-dip galvanizing
Dimensions
According to the current state standard 14918-80, the width of the sheets can be from 75 to 180 cm. Another state standard 19904-90 says that galvanized rolled steel can have dimensions from 850 to 3500 mm in length and from 750 to 5000 mm in width.
However, using sheets that are too large or too small is usually not very convenient. The most popular are 1000x2000 mm or 1250x2500 mm and up to 1 mm thick.
Such products do not weigh too much, and also do not take up much space, which makes their transportation very convenient, even on the roof of a car, which can easily carry up to 30 galvanized sheets of medium thickness.
The range of materials in terms of their main indicators is quite large, so before choosing, you should decide what size sheet will be most suitable for carrying out certain work.
You should be especially careful when creating a roofing covering, since a large number of factors must be taken into account:
- Roof dimensions;
- Possibility of delivery of sheets of certain sizes;
- Technological methods for lifting to the roof;
- Unloading methods and many other nuances.
As a rule, when building private houses or country cottages, standard sheets are used , the dimensions of which are 1 by 2 meters with a thickness of 0.55 mm. Instead, sometimes they take material 1250 mm by 2500 mm.
Weight
Not a single state standard strictly stipulates the weight of one galvanized sheet. However, this indicator is often very important, especially when you need to find out whether the vehicle can withstand the load. To calculate the mass of one sheet, you can use an indicator such as the specific gravity of the material, which is approximately 7.8 g per cubic centimeter.
Approximate weights in kilograms are given in the following table:
| Size, mm | Thickness, mm | |||||||||
| 0,5 | 0,55 | 0,6 | 0,7 | 0,8 | 0,9 | 1 | 1,1 | 1,2 | 1,3 | |
| 1000x2000 | 7,8 | 8,58 | 9,36 | 10,9 | 12,5 | 14 | 15,6 | 17,2 | 18,7 | 20,3 |
| 1250x2500 | 12,2 | 13,4 | 14,6 | 17,1 | 19,5 | 21,9 | 24,4 | 26,8 | 29,3 | 31,7 |
| Size, mm | Thickness, mm | |||||||||
| 1,4 | 1,5 | 1,6 | 1,7 | 1,8 | 2 | |||||
| 1000x2000 | 20,3 | 21,8 | 23,4 | 25 | 26,5 | 28,1 | ||||
| 1250x2500 | 31,7 | 34,1 | 36,6 | 39,0 | 41,4 | 43,9 |
It is worth noting that the cost of one galvanized sheet will directly depend on its thickness, size and, accordingly, weight. The heavier the sheet, the more money you will have to pay for it.
Rules for calculating weight
You can calculate the mass of one sheet using an ordinary calculator if you know certain rules. In particular, the weight is calculated by area. This method is suitable for metal of any thickness.
In order to determine this indicator, it is necessary to multiply the length, thickness and width of the material, and all indicators must be converted into meters. The resulting number is further multiplied by 7.65 kg/dm3 - this number indicates the density of the steel sheet.
As a result, a certain number will be obtained, which will indicate the mass in kilograms. It is multiplied by the number of sheets in the bundle, after which the information obtained is compared with the carrying capacity of the vehicle.
It should be noted that the mass of galvanized steel will practically not differ from ferrous metal, because the thickness of the zinc coating is minimal and is within a few micrometers.
Many virtual resources have at their disposal an application such as a metal calculator, with which you can calculate the mass of different grades of steel, including galvanized.
Blitz tips
- Galvanization is produced for general needs, for the production of corrugated sheets , for subsequent cold stamping or for applying paints and varnishes;
- This material can be used in the most severe climate conditions, including in the north. The main thing here is that it is of high quality, in which case it will be able to withstand even the most severe loads;
- Recently, polymer coatings have been applied to steel over galvanization, which can significantly increase the service life of such materials , and the thickness of the product does not increase significantly, nor does the weight;
- It is worth noting that not every paint and varnish product is suitable for application to a sheet of galvanized steel, which has a marking that says what kind of paint is allowed to be applied to the surface. As a rule, these are finishing enamels (this group includes polyvinylidene fluoride, polyurethane, polyester and other types of enamel), primers; protective epoxy enamel or polyvinyl chloride plastisol.

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

How to calculate the weight of sheet metal
To calculate the weight of a sheet of steel or non-ferrous metal, it is enough to know its overall dimensions. Fill in the required fields and the calculation will be performed automatically. Formula for calculating sheet mass:
where p is the metal density, s is the thickness, a is the sheet width, l is the rolled length;
Calculated values may contain errors. To obtain accurate data, use GOST reference books.
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—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—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.
