Weight and other characteristics of galvanized sheets: types, characteristics, weight calculation - SibNovStroy
29.04.2018
The weight of sheet metal products can be calculated by multiplying its specific weight (in kg/m2), that is, 1 m2, by the total area of the entire quantity of the product (m2). The weight of 1 m2 is calculated as the product of the specific density of the material and its volume, which is determined by multiplying the thickness by the width and length.
Galvanization is made from cold-rolled sheets. It consists of a base - a metal sheet - and a protective zinc coating. The densities of steel and zinc are different: 7850 kg/m3 and 7133 kg/m3, respectively. This means that the weight of a galvanized sheet not only consists of the weight of the steel base and coating, but also depends on their thickness, which can be different.
Galvanized sheets are produced in accordance with GOST 14918, which states that the sheet is produced with a thickness of 0.5–2.5 mm, but all dimensions and deviation tolerances must comply with GOST 19904 - it is used to produce cold-rolled steel for the base.
According to this GOST, sheets must be produced with a thickness from a certain range of sizes, in which the step of change in this characteristic between adjacent positions is: for rolled products up to 0.8 mm - 0.5 mm, 0.8–1.8 mm - 0.1 mm , 1.8–2.2 mm – 0.2 mm and for the last name – 0.3 mm. That is: 0.5, 0.55 and so on, then 0.8, 0.9 and further down the list.
However, GOST 19904 has an addition: at the customer’s request, it is allowed to produce sheets with dimensions different from those indicated above.
Production of galvanized sheets
But during implementation, as a rule, everyone indicates standard sizes. But in fact, the thickness, and therefore the weight of the sheets, may be less.
In addition, the thickness of the zinc layer on the sheet also varies. It depends on the class of this protective coating. At the end of the article there is a table of classifications indicating the corresponding thicknesses.
We measure the thickness of the sheet with a caliper or micrometer. In the accompanying quality document attached by the galvanizing manufacturer to its products, we find out the class of coating. Then we calculate the thickness of the steel base of the products (T1) - subtract the thickness of the coating (T2) from the total (T):
T1 = T – T2.
We calculate the specific gravity of the sheets (kg):
m = m1 + m2
where m1 and m2 are the weight of the base and zinc coating, respectively.
Measuring sheet thickness with a caliper
Substituting the dimensions for 1 m2 of the product and the density of the materials from which it consists, we obtain the formula:
m = T1*1*1*7.850 + T2*1*1*7.133.
Density has been converted from kg/m3 to t/m3 to avoid converting thickness from mm to m.
We calculate the total mass of the sheet: M = m*L*H, where L and H are the length and width, respectively, in meters, and m in kg/m2.
Let's calculate how much a 0.55 mm sheet weighs with dimensions 1×2 m and coating class 2. The thickness of the zinc layer is 0.0216 mm, and the thickness of the steel base:
T1 = 0.55 – 0.0216 = 0.5284 mm.
Calculation of the weight of galvanized sheets
Let us omit the intermediate calculation of specific gravity by immediately substituting all values into the formula for calculating m:
M = 0.5284*1*2*7.850 + 0.0216*1*2*7.133 = 8.604 kg.
From here we can get back the specific gravity:
m = M/2 = 8.604/2 = 4.302 kg.

Galvanized sheet - characteristics
Galvanized sheet is a product made of thin-sheet cold-rolled or pickled hot-rolled coil or sheet steel with a protective zinc or iron-zinc layer.
Such metal products are resistant to many types of corrosion and can withstand bending, drawing, stamping, and rolling. Areas of application: construction, mechanical engineering, household purposes.
GOST R 52246-2004 regulates the dimensions: the width of the galvanized sheet is in the range of 700-1800 mm, the roll is 500-1800 mm, the thickness together with the coating thickness is 0.3-4.5 mm.
Types and applications of galvanized sheets
These metal products are used both as an independent building material and as a semi-finished product for subsequent processing. Depending on the planned area of application, according to GOST 14918-80, the following categories of sheets are produced:
- for cold stamping – ХШ ;
- for cold profiling – KhP ;
- for painting - PC ;
- general purpose – OH .
According to GOST R 52246-2004, this classification is different:
- sheet 01 is used in the production of flat and curved products;
- for tableware and production of products by bending and locking – 02;
- for complex profiles and very deep-drawn stamped products – 03;
- for stamped products of complex drawing - 04, especially complex drawing - 05, very complex drawing - 06;
- for profiled products, grades 220, 250, 280, 320, 350 are used.
Currently, both standards are in force, but the second is more modern, it is characterized by clearer and stricter requirements for products.
Galvanized sheets are used to make corrugated sheeting, which is in demand in construction and is used for fencing, external wall cladding, and roofing. This material is also used in the production of bent forms: profiles for ventilated facades , drainage and smoke exhaust systems.
According to GOST R 52246-2004, the protective coating is divided into the following types according to its appearance and crystallization pattern:
- with a normal zinc crystallization pattern - N and ND (trained);
- with a minimal zinc crystallization pattern - M and MD (trained);
- iron-zinc – ZhTs and ZhtsD (trained).
The performance characteristics of galvanized sheets are largely determined by the thickness of the protective coating. The thicker it is, the higher the corrosion resistance, but the risk of zinc shedding during cold forming and cold stamping increases. A high-class coating is used for rolled products, used without an additional coloring layer.
Weight of galvanized steel sheet
When calculating the weight of a sheet with a protective zinc coating, the full thickness of the sheet (together with the coating), its length and width are taken into account.

Galvanized steel 1 mm: weight 1 m2, table, calculation formula
On average, the service life of galvanized sheets varies between 15-20 years. However, not all galvanized steel meets these standards. How to identify unscrupulous manufacturers? To find out, you need to calculate the weight of the galvanized sheet.
Galvanized sheet steel, sheet thickness 1 mm, weight 1 m2
Methods for calculating the weight of galvanizing:
- Determination using formulas;
- Determination of mass according to table data.
As for the table method, everything is simple here. The data provides a reference value for the mass of 1 square meter. galvanized steel, depending on its thickness.
For example, let’s determine the weight of galvanized sheeting of 1 mm, the area of which is 1 m2.
According to the aviation handbook:
- 1 square meter of galvanized sheet with a thickness of 1 mm will weigh 8.05 kg .

Weight of galvanized steel sheet
> Tips and ideas > Weight of galvanized steel sheets
Galvanized steel sheets have long been used in a wide variety of areas. For example, in construction, agricultural activities, advertising, etc.
In order not to be deceived by dishonest sellers from whom you will have to buy a similar type of metal, it is important to know the exact weight of galvanized sheet steel. This indicator can be calculated using a formula and making the most common, simple calculations.
Steel weight
The formula for calculating the weight of galvanized sheet steel looks like this:
M = M 1 + M 2,
Where M is an indicator of the weight of steel (usually calculated in kg), M 1 is the mass of all iron, and M 2 is the mass of zinc (also in kg).
At the same time, M 1 = t 1 * l 1 * h 1 * p 1, and here:
t 1 is an indicator of the thickness of iron, measured in mm. When making calculations, take into account the fact that the thickness of the iron is less than in the product, and in the 1st class of zinc coating the difference is 0.05 mm, in the 2nd – 0.03 mm.
l 1 – length of iron sheet, measured in meters;
h 1 – width of the same sheet, in meters;
p 1 – coefficient density. So, for iron it is 7.85 tons per cubic meter.
Also, there is a formula for calculating M2:
M 2 = t 2 * l 2 * h 2 * p 2, where:
t 2 – length of the entire coating, in meters;
l 2 – length of the coating, in meters;
h 2 – width of the same coating, in meters;
p 2 – coefficient zinc density. It is 7.13 tons per cubic meter.
To make it more clear, let’s make a calculation using an example, with a sheet of standard sizes: 1000 * 2000, mm; thickness 0.5 mm, as well as class 1 zinc coating.
M = 0.45 * 1 * 2 * 7.85 + 0.0381 * 1 * 2 * 7.13 = 7.608 kg
By making such calculations, you can find out a fairly accurate calculation of the weight of one galvanized sheet. This also applies to the entire batch of sheets that need to be purchased. By independently carrying out such calculations, you will be warned against deception by trading companies and organizations trying to make money dishonestly.
Similar formulas are recommended for brick density and foam volumes.

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:

Galvanized sheet, dimensions according to GOST 19904-90 (assortment)
Dimensions, maximum deviations and requirements for manufacturing accuracy for galvanized steel are established by the GOCT 19904-90 assortment in the same way as for non-galvanized cold-rolled sheet steel.
Galvanized steel according to specifications in accordance with GOCT 14918-80 is manufactured in widths from 700 to 1800 mm (size increments depending on the range of 50, 100 and 150 mm), lengths from 1000 to 6000 mm (size increments 20, 80, 100, 150, 200, 300, 500 mm), however, by agreement with the consumer, if necessary, other sizes can be installed.
The thickness of the galvanized sheet is regulated in the range from 0.5 to 2.55 mm, and the assortment determines the following dimensional step:
- thickness range 0.5-0.8 mm - step is 0.05 mm;
- range 0.8-1.8 mm - step 0.1 mm;
- range 1.8-2.5 - step 0.2, last - 0.3 mm.
Weight of galvanized sheet
The weight of a galvanized sheet (one square meter) can theoretically be calculated using the formula:
M=M1×t1+M2×t2 (1)
Where:
- M - weight of 1 m² of galvanized sheet, kg;
- M1 - weight of 1 m² of steel sheet without a cladding layer 1 mm thick;
- t1 is the thickness of the steel sheet without coating;
- M2 - weight of 1 m² of zinc cladding layer 1 mm thick;
- t2 is the thickness of the zinc layer on both sides of the sheet.
The specific gravity of carbon steel is 7.85 g/cm³, or, for convenience of calculations, it is generally accepted that 1 m² of sheet steel with a thickness of 1 mm weighs 7.85 kg. The specific gravity of zinc is slightly less - 7.13 g/cm³, that is, 1 m² of zinc with a thickness of 1 mm weighs 7.13 kg. Taking into account these quantities, formula (1) can be rewritten:
M=7.85×t1.13×t2
The thickness of the zinc layer depends on the coating class (GOCT 14918-80) and is indicated in the symbol:
| Class | Limit values for layer thickness, mm | Weight of tread layer on both sides, kg |
| I | From 0.018 to 0.04 Average value 0.029 | 0.258-0.570 Average 0.414 |
| II | From 0.01 to 0.018 Average value 0.014 | 0.1425-0.258 Average 0.200 |
| P (increased) | From 0.04 to 0.06 | 0.57-0.855 Average 0.712 |
To calculate the weight of a galvanized sheet, you can also use a formula that takes into account the weight of the coating depending on the class of layer thickness:
M=7.85×t1+Mp.s., where:
- M - galvanized sheet weight 1 m², kg
- t1 is the thickness of the steel sheet without coating;
- Mp.s. - the average weight of the tread layer depending on the thickness class, the value is standardized by GOCT 14918-80.
To calculate how much a galvanized sheet weighs (the weight of one sheet of the required size), use the formula:
Msheet=M×S, where:
- Msheet - weight of one galvanized sheet, kg;
- M – weight of 1 m², kg;
- S—sheet area, m².
Considering that the GOST 19904-90 assortment allows deviations from the design weight of up to 3% (due to regulated maximum deviations in thickness, length and width), as well as taking into account the small thickness of the cladding layer and the small difference between the specific gravity of steel and zinc alloy ( which may contain lead and aluminum), the theoretically calculated mass may differ slightly from the actual weight.

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.

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.

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.

Weight of galvanized sheet steel: calculation formulas, tables
>> Weight of galvanized sheet steel: calculation formulas, tables
Galvanized sheet steel has a wide range of applications: entrance doors, automotive production, summer cottages, housing, advertising industry, etc.
In order not to look like an incompetent buyer in the eyes of unscrupulous sellers, you must be able to make simple mathematical calculations of the weight of steel. And most importantly, ask the sellers for documents confirming compliance with the State Standards.
Galvanized steel from the manufacturer must meet all requirements and especially GOST. Therefore, before purchasing such material, be sure to read all the documentation.
Formula for calculating the weight of galvanized steel
You will need a tape measure and a calculator. Tip: enter the formula in Microsoft Office Excel and substitute the necessary numbers, the program will recalculate everything itself. Or use the tables below.
- m=m1+m2
- m – final weight (kg),
- m1 - weight of iron sheet (kg),
- m2 is the weight of zinc (kg).
Iron sheet mass formula
m1= t1 x l1 x h1 x p1
- t1 is the thickness of the iron sheet (mm). Remember that in manufactured products the thickness decreases: for class I by 0.05 mm and by 0.03 mm for class II;
- l1- sheet length, (m);
- h1 - sheet width (m);
- p1- density (7.85 t/m3)
Zinc mass formula
- m2 = t2 x l2 x h2 x p2
- t2 - thickness, (I class 0.0381 mm, and II class - 0.0216 mm);
- l2- length (m);
- h2- width (m);
- p2-density - 7.13 t/m3
We will calculate the weight of the sheet with the following parameters: 1000*2000 mm, 0.5 mm thick with class 1 zinc coating. m= 0.45 x 1 x 2 x 7.85 + 0.0381 x 1 x 2 x 7.13 = 7.608306 kg or abbreviated 7.608 kg.
In this way, we calculated the weight of one galvanized sheet, and if we multiply, we get the total weight of the purchased batch.

Weight and other characteristics of galvanized sheet: types, characteristics, weight calculation
Galvanized sheets are in demand in many areas, due to their qualities such as excellent performance characteristics and affordable price. For the most part, this material is in demand in the construction industry, where it is used to construct roofs, fences, outbuildings, etc. There is also interest in such sheets from mechanical engineering enterprises.
How it is produced
Most often, ST08PS metal is used to create galvanized sheets. The abbreviation “PS” is used to designate semi-quiet steel. boiling and semi-boiling types cannot compete with it . In some cases, other types of steels can be used to create similar sheets:
- St1 (2 or 3);
- 08kp;
- 08ps;
- 08Yu, etc.
According to the technology for manufacturing galvanized sheets, the following steps must be carried out:
- First, the hot-rolled metal strip is processed, from the surface of which scale is removed. For this operation, the acid etching method is used. There are often cases when cold-rolled carbon steel coils are used in the manufacture of galvanized sheets.
- The workpiece is subjected to special processing, which amounts to piercing on a special machine. This operation makes it possible to provide the strip with the required thickness.
- At this stage, the metal is annealed.
- The production of sheets is completed by galvanizing, for which a special apparatus is used.
The main regulatory document on the basis of which the range of procedures is formed is GOST 19904-74 . Zinc is not the only material that can be used for this operation. Other metals such as aluminum and lead can also be used.
Such metal sheets are often made using zinc grades Ts0 and Ts1. The zinc layer on such profiles most often has a thickness of 0.01-0.06. In some cases, the sheet may be treated with a special oil, which can be replaced by an operation such as passivation. All such work represents a process such as galvanizing preservation. This is done in order to provide a higher level of protection of the metal from corrosion.
Main varieties
There are several types of galvanized sheets:
- profiles for painting;
- general purpose profiles;
- profiles designed for cold profiling;
- products intended for cold stamping.
Within the last group, several more subspecies can be distinguished depending on the extraction capabilities:
- N – normal;
- G – deep;
- VG – very deep.
Based on the uniformity of galvanizing thickness, such profiles can be divided into:
- NR – normal thickness variation;
- UR - moderate thickness variation.
In modern conditions on the market you can find profiles with deep, regular and very deep drawing.
Scope of use
Such sheets will be an excellent choice for creating a wide variety of designs, due to the performance characteristics of zinc. Based on these sheets the following can be created:
- building drains;
- buckets and tanks;
- steel profiles, which can be used for the manufacture of frames for finishing materials;
- car bodies;
- corrugated and smooth roofing sheets;
- pipes and shut-off valves.
Quite often this material is used in areas where increased demands are placed on the material’s resistance to various external factors. For example, a galvanized profile 1 mm thick has become widespread in the field of mechanical engineering, where various types of devices are made on its basis. Also, sheets with a thickness of 0.5 mm can be a good option for roofing.
https://www.youtube.com/watch?v=KKSmd0u53KM
Galvanized sheets offered in specialized retail chains have a thickness of about 0.5-1.9 mm, a length of 2000-2500 mm, and a width of 700-1800 mm.
How is the weight of galvanized sheet calculated?
Considering that galvanized sheets are widely used in construction and other industries, it is often necessary to calculate the required number of profiles . To determine the weight of galvanized steel, you do not have to resort to complex techniques. A formula well known to everyone from high school can help with this:
M = M1 + M2,
Where:
M - corresponds to the mass of the profile,
M1 - indicates the weight of steel,
M2 - indicates the weight of zinc.
In practice, to determine the weight of galvanized profiles, a slightly different method is used. Help in this matter is provided by tables or specially developed programs.
State standard requirements for profile quality
Any material with zinc coating must be created in compliance with all GOST requirements. Regarding galvanized profiles, the following requirements can be distinguished:
- the thickness of the zinc layer on the surface should be the same in each area;
- the surface should not have torn edges;
- the presence of sagging on the surface of the profiles must be excluded;
- After mechanical treatment of galvanized surfaces, there should be no damage to them.
Corrugated sheet
This material is a type of galvanized sheet that is in demand in the construction industry. The regulatory document defining the requirements for its production is GOST 24045-94.
With the help of corrugated sheeting, you can provide high protection for the roofs of houses, as well as create a variety of enclosing structures based on it. The high demand for this material is primarily due to its high lateral rigidity. Corrugated sheeting is able to successfully cope with significant loads.
In addition to this, it holds water well and does not create problems when painting.
Conclusion
In modern conditions, it is not surprising that galvanized sheets are very popular in many areas. With their high strength and affordable price, they are an excellent choice for solving various problems.
However, when choosing such profiles, you must pay attention to the product labeling . It must indicate compliance with GOST. It is these galvanized sheets that are able to fully demonstrate all their best qualities.
Therefore, the choice in favor of such products will be the most correct.

Theoretical weight of steel sheet and maximum deviations
Knowing the cost per ton, it is easy to calculate the price of 1 metal sheet. To do this, you need to know the weight of a unit of production. The table below shows the theoretical weight for sheets with a thickness of 0.5 - 60 mm of the most popular and in demand cutting - 1250x2500, 1500x6000 and 2000x6000 mm (depending on the thickness of the metal).
It should be noted that this table can be used to determine the approximate cost of a metal sheet, since the weight of rolled products is determined for a standard steel density of 7.85 kg/m3 and may vary slightly depending on the grade of steel and the technical conditions of the manufacturer.

Limit deviations in sheet metal production
Any sheet metal is produced with dimensional deviations in length, width, thickness, the magnitude of which depends on the rolling equipment. For hot-rolled products in accordance with GOST 19903, produced in sheets, the following maximum deviations exist:
- the width is +10 mm (for rolled products with a cut edge) or + 20 mm (for rolled products with an uncut edge)
- the length can vary from +10 (for sheet lengths up to 1500 mm) and up to +15 mm (for sheet lengths over 1500 mm)
In addition, the tolerances in the dimensions of metal sheets depend on:
- rolling accuracy (increased, normal accuracy)
- purpose of rolled products (rolled products for the aviation industry can be produced with minus tolerances)
Sale of metal taking into account possible tolerances
Changes in dimensional parameters by the magnitude of maximum deviations affect an increase in the weight of a rolled unit. As a result, after weighing and when shipping products, the price may increase slightly compared to the theoretically calculated value.
APEX METAL sells sheet metal not only in rolls and sheets of standard cutting, but also provides plasma, gas, laser cutting, longitudinal and transverse cutting services. The cost of sheet metal depends on the grade of steel (high-quality steel, alloy steel or carbon steel of ordinary quality), the method of surface treatment and the volume of purchased products.

- According to technical literature, the service life of galvanized sheets ranges from 15 to 20 years. But does all galvanized steel meet this requirement? You have probably already witnessed how not even a year has passed, and rust is already visible on the surface of a sheet. This happens due to the thickness of the protective coating being too thin. So how to recognize such an unscrupulous manufacturer? The weight of the galvanized sheet will help us answer this question.
- 1st class - 38 microns;
- 2nd class – 22 microns.
- To determine the dimensions of the profile of supports and floors. Based on the weight of the sheets, the load on the load-bearing elements of the metal structure is determined. Neglect of this point leads to premature destruction of the structure;
- The weight of the sheet steel gives an idea of the thickness of the galvanized surface. If the sheet weight exceeds its nominal value, while the total thickness corresponds to the declared value, this indicates that the sheet is galvanized of poor quality. The amount of zinc on the metal surface is underestimated, which will negatively affect its service life.

Galvanizing
To better understand the situation, let’s first look at what the galvanizing process is. Galvanizing is the application of a galvanic coating to the surface of a metal, the main element of which is zinc. The thickness of zinc depends on the coating class:
The main task of galvanizing is to guarantee protection against corrosion to steel sheets.
It is known that most metals tend to oxidize under normal atmospheric conditions. The oxidation process is destructive for them and leads to a kind of surface abrasion (corrosion).
Some metals (zinc, copper, aluminum) prevent these reactions by forming a dense film of oxides that prevent further penetration of oxygen deeper. Others, which include iron, when interacting with oxygen, form a loose, fragile film, which contributes to the occurrence of oxidation processes. As a result, the sheets begin to become rusty. Applying zinc to the surface of such a metal solves this problem.
Why do you need to know the mass of a leaf?
The following points need to be highlighted here:
Methods for determining the weight of galvanization
There are 2 methods for determining the mass of galvanized sheet steel:
The tables are more or less clear. They give a reference value for the mass of 1 sq.m. galvanized steel depending on its thickness. You can find them in technical literature.
As an example, let’s calculate the weight of galvanized sheeting of 0.5 mm with an area of 2 square meters. meters.
According to the Aviation Scales Handbook:
Multiplying the value we need by the size of our area, we find that the sheets weigh 8.26 kg.
Table
| Sheet, mm | Weight 1 m2, kg |
| 0,40 | 3,34 |
| 0,45 | 3,73 |
| 0,50 | 4,13 |
| 0,55 | 4,52 |
| 0,60 | 4,91 |
| 0,65 | 5,31 |
| 0,70 | 5,70 |
| 0,75 | 6,09 |
| 0,80 | 6,48 |
| 0,90 | 7,27 |
| 1,00 | 8,05 |
| 1,10 | 8,83 |
| 1,20 | 9,62 |
| 1,50 | 11,97 |
| 2,00 | 15,90 |
| 2,50 | 19,82 |
The second method is somewhat more complicated. The basic formula for calculating the weight of galvanizing looks like this:
Total sheet weight=steel weight + galvanized part weight
The weight of steel is found from the following ratio:
steel weight=sheet length*sheet width*steel thickness*steel density
Density for steel alloys is a reference value and is 7850 kg/m3.
As for the thickness of the steel, it depends on the class by which the sheet is galvanized (the value of the thickness of zinc is indicated above):
Steel thickness = total sheet thickness – zinc thickness
The weight of the galvanized layer is determined in a similar way. When calculating, it is necessary to pay attention to compliance with the dimensions of the quantities.

Weight of galvanized sheet. Table
The material is produced by cold rolling. Its thickness parameter is 0.3-1.2 mm, which directly affects the weight of the galvanized sheet. In addition to the indicated thicknesses, they are also produced with a higher parameter (1.5-2.5), which is due to the scope of application. The anti-corrosion coating is applied to it one-sided or two-sided, the main factor being uniformity.
According to regulatory documents, the service life of galvanizing is 15-20 years. However, in reality this figure may be significantly lower, which is due to the quality of the sheet and the application of the zinc layer on it. The shortening of this period is due to the low thickness of the coating. To reduce the risk of purchasing low-quality material, it is necessary to evaluate such an indicator as the weight of the galvanized sheet.
Based on the thickness of the sheet, 3 classes of material are distinguished:
Based on the type of leaf, there are 4 categories:
The main purpose of the material is the creation of building structures, such as canopies, ebbs, as well as dishes - cans, etc. The application is not limited to aggressive environments, which is due to the high-quality coating that is resistant to such influence.
It is used during temperature fluctuations, in humid environments, and in direct contact with liquids. Traditional steel does not have such wide capabilities.
The advantages of galvanized sheets 5 mm or more include low weight and high strength, which is important in construction.
Depending on the application and the required qualities, sheets with a crystallized pattern, which are designated KR, can be used. Without it, the sheet nomenclature includes the MT index.
Calculation methods
To determine the mass of a sheet, two methods are used:
The table (see below) provides a reference value for the weight per square meter of material area depending on the thickness. Such tables are available in reference books; they indicate the following indicators:
For example, we can consider the mass of a sheet with an area of 14 square meters. m, having a thickness of 0.7 mm. To do this, you need to multiply these indicators by each other. As a result, we get a total mass of 79.8 kg.
In accordance with theoretical research, to calculate the weight parameter of one sheet, you can use tables “Weight of galvanized sheet” No. 1 and No. 2.
Table No. 1.Without coatings
| Sheet thickness, mm | Weight of one square meter, kg |
| 0,40 | 3,34 |
| 0,45 | 3,73 |
| 0,50 | 4,13 |
| 0,55 | 4,52 |
| 0,60 | 4,91 |
| 0,65 | 5,31 |
| 0,70 | 5,70 |
| 0,75 | 6,09 |
| 0,80 | 6,48 |
| 0,90 | 7,27 |
| 1,00 | 8,05 |
| 1,10 | 8,83 |
| 1,20 | 9,62 |
| 1,50 | 11,97 |
| 2,00 | 15,90 |
| 2,50 | 19,82 |
In both tables, the information given from the special reference book allows you to perform calculations only approximately.
Table No. 2. With applied polymer layer| Sheet thickness, mm | Weight of one square meter, kg |
| 0,4 | 3,14 |
| 0,45 | 3,53 |
| 0,5 | 3,94 |
| 0,55 | 4,31 |
| 0,6 | 4,69 |
| 0,65 | 5,08 |
| 0,7 | 5,49 |
| 0,75 | 5,88 |
| 0,8 | 6,29 |
| 0,9 | 7,09 |
| 1 | 7,94 |
The second calculation method is more labor-intensive. In order to calculate the mass, you need to perform several actions:
Total sheet mass = mass of all steel + mass of zinc coating.
To calculate the mass of all steel, you need to multiply the volume by the density:
Weight of total steel = sheet length * sheet width * steel thickness * steel sheet density
The last figure is a reference value, which is 7850 kg/cubic meter. m.
Steel thickness = total sheet thickness – zinc thickness.
The thickness of galvanizing is indicated in the tables above.
Why is it necessary to know the mass of a leaf?
This indicator is needed to determine the profile dimensions of columns and beams, which is due to the creation of a load from the sheet’s own weight on the supporting structures. The absence of this value in the calculations can lead to premature failure of buildings from normal operation.
The second reason is to determine the quality of the coating. Depending on the correspondence of the values obtained as a result of calculations to the actual data, one can judge the quality of the coating and the compliance of its thickness with established standards.
With a small amount of zinc on the surface, the duration of trouble-free operation of the product is reduced.
Why are sheets galvanized?
Galvanizing as a process is the galvanic coating of a steel surface with zinc. Depending on the class of coating, the thickness of the layer is determined: class 1 - 38 microns, class 2 - 22 microns. This layer is used as an anti-corrosion coating.
Galvanized sheets of 1.0 mm and other thicknesses are not subject to oxidation (corrosion) under normal conditions. Therefore, the preservation of the original performance characteristics continues for 15-20 years.
Certain types of metals, such as Zn, Al, Cu, protect the steel sheet by forming a dense film of oxides on its surface, which does not allow oxygen to penetrate the metal body.
In the absence of such a layer, oxidation occurs over time, the formation of a loose structure and a weak film that does not prevent this process.
As a result, corrosion appears on the surface, which can penetrate the metal structure and form a through hole. Applying a layer of zinc prevents this type of damage.
