Online calculator – Calculate the weight of a channel of 1 linear meter according to GOST + TABLE

How to calculate the weight of a channel?

The easiest way is to refer to GOST 8240-97 and find the required type and size in the table. Each element of the assortment has a theoretical weight of one meter. This value must be multiplied by the length of the product.

You can also calculate the mass of the channel without reference books, using the formula. First you need to find the cross-sectional area of the channel.

– channel height, mm
b
– flange width, mm
t
– flange thickness, mm
s
– wall thickness, mm
ρ
– metal density

To obtain the weight, the cross-sectional area must be multiplied by the length of the rolled product and the density of the metal from which the rolled product will be made.

– cross-sectional area
ρ
– metal density
L
– length

The calculation using the above formula does not take into account the radii of curvature of the channel corners.

A channel is a structural element made of metal, the cross section of which forms the letter “P”. It has walls with a shelf. In cross-section, the wall is a lintel, and the shelves act as walls. Production is carried out according to standardized sizes. Thus, the height of the product is determined by the height of the walls. You can calculate the weight of a channel using our calculator. Below are GOST tables for selecting the required values.

The product is made from rolled steel. The hot rolling method is used in production. For this purpose, sectional machines are used. The inner edges of the shelves are made with a slight slope or made parallel to each other. Note that the channel number indicates the height of the product.

Channels are used wherever construction work is required. They are also used in the automotive industry. However, special types of channels are used there. Often it can be used to reinforce reinforced concrete structures or as an independent material that allows making frames, floors and ramps.

Channel length in production according to standards

The size of the channel supplied by the manufacturer is strictly regulated by the relevant state standard.
The range of hot-rolled channels for special and general purposes is given in GOST 8240-97. According to this regulatory document, the channel is manufactured in lengths from 2 to 12 meters. At the customer's request, it is possible to produce a U-shaped profile, the size of which exceeds 12 meters. It can be produced in measured and multiple measured lengths, as well as unmeasured. Important note! In accordance with GOST, one batch of measured or multiple lengths may contain up to 5% of the total mass of a channel of unmeasured length.

Bent equal-flange channel, its dimensions and maximum deviations are regulated by the interstate standard GOST 8278-83. In accordance with the requirements of this document, the length of the channel should be 3 - 11.8 meters. At the individual request of the customer, this profile can be manufactured in a size of 12 meters. The channel can be measured, unmeasured and a multiple of the measured length.

In addition, the presence of unmeasured segments is allowed in one batch, the mass of which should not exceed 7% of the total mass.

Formula for calculating channel weight

The calculation is made using the formula: M = ρ *L*s (2*b+h-2*t);

where ρ is the density of the material;
b – shelf width;
t – average flange thickness;
s – wall thickness;
h – beam height.

Assortment of bent channel according to GOST 8278-89

The range of bent channel complies with the following standards: • equal-flange section - GOST 8278-89; • unequal section - GOST 8281-80. The number of bent channels in the assortment table corresponds to its size, expressed in cm. In the marking, the cold-formed profile has a numbering consisting of three digits. The designation according to GOST displays the distance in millimeters: between edges, edge width, metal wall thickness. The most popular sizes of bent channel: 60x32x4, 60x40x4, 80x40x3, 80x40x4, 80x50x4, 80x60x3, 80x60x4, 100x50x3, 100x50x4, 120x60x4, 140x60x4, 160x80x4 , 180x80x5, 200x100x6. For example, in the designation of a channel by marking 40x30x2.5 it is easy to find out what dimensions the bent one has profile: 40 is the distance between the shelves (mm), 30 is the width of the shelf (mm), 2.5 is the wall thickness (mm).

The weight of a bent channel in an assortment may vary depending on its dimensions. In the presented table of the mass of 1 linear meter of bent channel, the spread in the theoretical weight values is ensured due to the different heights of the walls and thickness of the shelves. The specific weight of a U-shaped profile starts at 1 kg per 1 meter and can reach 11 kg for a 170 cold-formed profile, resulting in a very wide range of sizes and weights of bent channel. The wall thickness also does not remain constant and varies from 2 to 6 mm.

The bent channel closest to the GOST characteristics is marked with the letter A - high accuracy. A less precise cold-formed channel is marked with the letter B - increased accuracy, and rolled metal of normal precision is marked with the letter B. An important parameter of bent rolled metal is not only its standard size, but also the weight per linear meter. You can find out how much a bent channel weighs and its geometric dimensions by studying the table of the theoretical weight of a channel presented in our assortment. In the usual case, the mass is calculated quite simply, but only if its shape is made by bending from rolled sheets. Those. When calculating the mass of a bent channel, an equal-flange product is considered, the internal edges of the walls of which are located parallel to each other. There are also unequal flange profiles, for which the calculation of mass is somewhat more complicated due to the difference in the length of the flanges.

Heavy engineering. Here, the products in question are used in metal structures that are subject to large axial or bending loads. As a rule, these are crane beams, building structures, and so on.
Machine tool industry.
Automotive industry.
Car manufacturing.

How much does 1 meter of channel weigh | Standard sizes

Modern construction cannot do without innovative solutions, thanks to which it is possible to significantly strengthen structures and buildings. Hot rolled metal is just that. The U-shaped profile is widely used in various construction works, in the construction of metal structures of medium and high importance.

It is important for customers to know how much a meter of channel weighs. The parameter directly affects the total weight of the entire metal structure. Standard sizes with different numbers have their own weight, which is clearly regulated by GOST 8240-97

. This is the main document that guides manufacturing plants when creating metal profiles. Depending on the models - from No. 5 to No. 40, the products weigh from 4.84 to 48.3 kg - this is the weight of a linear meter of channel.

Ordering a channel: what characteristics you need to know

Metal products for the construction of structures of varying complexity are selected strictly according to the required parameters. The abundance of standard sizes and their modifications makes it easy to choose the most suitable type. Most often, two modifications of channel products are selected:

With parallel edges. Metal products are used in the construction industry, including for repair work and the creation of metal structures of varying complexity. The parallel edges have the optimal distance for laying bricks. Creating and strengthening openings with their help is easy.
With slanted edges inward. The second most popular version of channel models is used in the field of small and large construction.

There are additional types of metal products that are in demand. Profiles can be special, economical, and lightweight. They are marked with the letters “S”, “E”, “L”, respectively. Special and economical products are made to order. The first is based on the personal dimensions of customers, the second is with reduced shelf thickness. This allows you to reduce the total weight of 1 m of channel and the entire finished structure.

The lightweight standard size is suitable for less critical buildings where it is not necessary to create a large-scale stiffening frame. The marking “a” is placed on models of the “P” and “S” series. It denotes the weighted mass of the channel. Most often, metal depots always have categories “P” and “U” in stock - they are in demand among customers.

How much does a channel weigh, other sizes

For production, the standard steel used is St3ps-5 grade - the basis for the strength and indestructibility of metal structural parts. Hot-rolled models are produced from other suitable steel grades - carbon, high-alloy, atmospheric corrosion-resistant. 09G2S is often added to the St3 brand. The table below shows the weight characteristics of metal products.

Number	Channel weight P	Channel mass U	Channel mass E	Channel mass C	Channel weight L
4,84	4,84	4,79
6.5	5,9	5,9	5,82
7,05	7,05	6,92	11,8
8,59	8,59	8,47
10,4	10,4	10,24	5,02
12,3	12,3	12,15	18,51	5,94
14,2	14,2	14,01	21,95	7,1
16,3	16,3	16,01	25,7	8,49
18,4	18,4	18,07	28,83	10,12
	21	21	20,69		11,86
	24	24	23,69	44,46	13,66
	27,7	27,7	27,37		16,3
	31,8	31,8	31,35	43,88	19,07

The linear weight of channels should not exceed 6%

. Such regulations are prescribed in a state document. Taking into account the tolerances for maximum deviations in total, the weight of a meter of channel should not exceed 7-8%. If violations are noticed in the production regulations, then the metal profiles are considered unsuitable.

Where to buy channel products?

sells rolled metal throughout Russia. Thanks to many years of contractual relations with the largest manufacturing plants of metal standard sizes, steel angles, and beams, it was possible to achieve a price list with minimal prices. Regular customers buy rolled metal at a special price, on individual terms.
