How to calculate the weight of an iron sheet - Metals and their processing

Weight of galvanized sheet steel: calculations

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:

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.

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.

Sheet Metal Weight Chart: How to Calculate the Specific Gravity of Aluminum

It is not always possible to weigh rolled metal, and in this case it is necessary to determine the mass of the sheet or batch in other ways. There are several of them: using a formula, using online calculators or using tables.

The weight of the sheet is calculated using the formula:

M = H*A*B*7.85 , in which:

M – mass, kg;
H – thickness, mm;
A – length, m;
B – width, m.

7.85 kg/dm3 – average density of carbon steel. This value corresponds to the mass of a metal sheet with an area of 1 m2 and a thickness of 1 mm . If accurate calculations of a large batch of rolled sheets are required, instead of the average density value, use the exact value determined from the reference book.

To calculate the mass of a batch of rolled sheets, including sheets of the same size, the calculated mass of one sheet is multiplied by the number of sheets in the batch.

How to determine the mass of a sheet of non-ferrous metal?

If you need to find out the mass of rolled sheets made of non-ferrous metal or alloy, you can use the formula given above. Only instead of the density of steel, substitute the density of the corresponding metal or alloy, kg/cm3:

aluminum – 2.7;
titanium – 4.5;
zinc – 7.14;
tin – 7.29;
copper – 8.94;
lead – 11.34.

How to find out the mass of a sheet of metal using an online calculator?

To determine the mass of a sheet made of an alloy based on iron, non-ferrous metals and their alloys, you can use an online calculator with fairly high accuracy. This service allows you to get results for steels of various grades, cast iron, aluminum and its alloys, copper, brass, bronze, titanium, nickel, zinc.

In addition to sheet metal, this service allows you to accurately calculate the weight of bars with round, square, hexagonal cross-sections, angles, I-beams, channels and, with approximate accuracy, periodic profile reinforcement.

In this article we will look in detail at how the weight of each steel sheet is calculated, depending on its cutting, thickness, steel grade, etc.

The weight of a sheet of carbon steel, st. 3, is calculated using a certain formula and can be calculated quite easily on a calculator. For example, we will cut sheet 3 to 2019 mm width and 2019 mm length - this is the standard cutting of sheets (the most common sheets we will cut are 1250x2500 mm).

To calculate the weight of 1 sheet 3x1250x2500 mm, you need to multiply all dimensions in terms of values converted into meters - 3x1.25x2.5x7.85 = 74 kg.

The theoretical weight turned out to be 74 kg, but you need to take into account whether the sheet has a cut edge or not, since if the sheet is made by ASA, then its edge will not be cut, so you need to add about 10-15 kg to the sheet, depending on the size of the sheet. So, in the end the weight of the sheet is approximately 90 kg .

Upon weighing, the weight will be slightly different, but no more than 90 kg! Our company ArtStalUral, after weighing the sheet, if the weight of the sheet is less, returns the money to the bank account, based on the letter of refund and the reconciliation report . We have many steel sheets in stock in cities such as Yekaterinburg, Chelyabinsk, Perm, Tyumen, Izhevsk, Surgut, St. Petersburg and Moscow!

Weight of stainless steel sheet st. 08x/12x18n10t food grade is calculated in approximately the same way as carbon steel 3, only the density coefficient is approximately 7.9. For example, we take a sheet of 2.5x1000x2000 art .

12x18n10t, sheet weight is calculated as 2.5x1x2x7.9=39.25. You don’t need to add much to the theoretical weight of a stainless steel sheet, approximately 3-5 kg per sheet up to 3 mm thick . The total weight of a sheet of 2.5x1000x2000 mm st. 12x18n10t stainless food grade is 44 kg .

You can buy stainless steel sheets from our company.

Corrugated steel sheet is calculated in the same way as ordinary carbon steel st.3. The formula is shown above.

When calculating galvanized steel sheet, it is necessary to add approximately 3% to the weight of the carbon sheet. For example, a galvanized sheet 0.5x1250x2500 - the weight of the carbon sheet is 12.2 kg + 3% = 13 kg . Also, when calculating the weight of any other galvanized products, add 3% to carbon products. You can also buy galvanized products from our company!!

A sheet of steel weighing 1 m2 is also calculated using the formula. For example, a sheet 2x1250x2500, then we multiply 2x1x1x7.85 = 35.7, the weight of 1m2 of a 2mm sheet is approximately 40 kg.

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.

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.

How to calculate the mass of a sheet of metal

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.

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.

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.
