Technical characteristics of the channel: main types, differences, weight per linear meter
Channels are one of the most popular types of metal products. Like all metal products, they have their own specific characteristics. Due to its inherent versatility, this type of rolled metal is used very widely. In the construction industry, when installing load-bearing structures (supporting elements, frames, bases) of various products, industrial production, as a rule, this profile is used.
The main advantages of the channel
A clear advantage is the geometric shape, in the form of a “P” . The ability to withstand heavy loads, strength and rigidity make this profile irreplaceable. It has excellent resistance to deformation and reliably withstands all bending forces. Channels are often used as reinforcing parts in reinforced concrete structures. But, alas, like any ferrous metal, they have low corrosion resistance.
If this metal is installed outside the concrete body, then it must be protected by priming, painting, processing protective mastic, etc. Sometimes, if the products will be used in an aggressive environment, with a wide amplitude and sudden changes in temperature, as well as with high humidity, technologically justified is the choice of stainless material.
Scope of use
In addition to standard applications, the profile also has non-standard solutions for use. For example, a perforated profile allows the installation of metal structures without welding, which significantly reduces installation time. As a rule, for this I use products that have a large shelf height and sufficient width between them. This profile is often used in the construction of warehouse racks.
This type of rolled steel is widely used as guides for lifting equipment. Ramps for carts are made from it. It is often used as a frame during the wiring of communication networks. Certain types of this rolled metal are used for automotive products, for the repair and construction of cars and other parts in mechanical engineering.
Kinds
This type of rolled metal is divided into several types . Profiles can be bent, hot-rolled, unequal and equal flange, with parallel flanges, with internal slope of flange edges, special ones. The main difference between a bent profile is the roundness of the outer corners. The size of the channel produced by manufacturing plants varies in the range of 3.5-11 m. Taking into account the length, products are divided into unmeasured, multiples of measured and measured .
Channels are also divided into high and standard precision products. During the manufacture of channels, steels with different amounts of carbon are used. For example, a hot-rolled channel does not have a high degree of accuracy and is sometimes difficult to work with. A curved channel has more precise dimensions and does not have the disadvantages that are inherent in hot-rolled products. Working with a bent channel is much easier.
Dimensions
The height of the product indicates its conditional number and the scope of definition is practiced.
For example, channel No. 8, as a rule, is used for reinforcing structures ; during its manufacture, calm and semi-quiet steel is used, which provides this type of rolled metal with good weldability.
And channel No. 10 has higher strength indicators and load-bearing capacity than No. 8, this makes it possible to reduce the metal consumption of structures. The area of use of channels is determined by both the size and grade of metal.
For example, when a steel channel is made of low-alloy steel, which is resistant to critically low temperatures, then it is more appropriate to use it in conditions where channels made of other steel will be brittle, for example, in the Far North.
The most popular standard size - No. 16 is made from low-alloy, semi-mild and mild steels. Welding of a channel made from this steel can be done without preheating the product, and subsequent heat treatment is not required.
There are five main types of channel:
- U - have some inclination of the inner edges of the shelves;
- P - have parallel edges of the shelves;
- C - special;
- L - light series;
- E - economical.
According to GOST rules, the largest product size is 12 meters , but longer profiles are also allowed.
Weight of 1 meter of channel
To find out how much the weight of a linear meter is, you need to know the following values:
- the density of the metal from which the product is made;
- cross-sectional area of the profile.
The cross-section of a product is defined as the total areas of its shelves and walls. It is easiest to calculate this value for a profile with parallel parts of the structure.
The weight depends significantly on the height of its walls. For example, for channel No. 8 the weight range is between 2 and 13.8 kilograms , taking into account its dimensions. And the thickness of the walls, in this case, can differ by 3 times - from 30 to 120 millimeters. Therefore, the weight of a particular product needs to be calculated.
In GOST, the abstract value of 7.85 g/cm is taken as density. cube But in fact, the density differs both less and more, it depends on the type of steel alloy that is used to make the channel. A little about the content of carbon steel - on the left of the name there are two metal markings - these are “Steel” and “St” and two markings on the right - these are “Sh” or “A”. The differences between them are in the amount of impurities, and this is the permissible amount of phosphorus and sulfur.
In addition to impurities, alloys of alloyed metals may also contain specially added materials, for example, chromium, nickel, and so on. Their part can reach up to 50% of the metal composition, which is also important to take into account when determining the question of how much a meter of a product weighs, searching for this value according to the required assortment. Since we calculate the weight in cubic centimeters, we need to convert the length of a linear meter into centimeters:
Then, to determine the volume of the figure, you need to multiply the cross-sectional area of the product by its length. Let's make the following calculation for channel No. 10 (the cross-sectional size can be found according to GOST):
We determine the weight of channel No. 10; for this we take the most common steel grade St3ps, widely used for the production of this product. The density of this steel is 7850 kg/m. cube or these same ones, 7.85 g/cm. cube according to GOST, we calculate:
- 1090 cm3 x 7.85 g/cm. cube = 8556.5 g. or 8.5567 kg.
The calculation is applicable for channel No. 20 and others. If you need to determine in more detail the standards that exist for channels of various types, then we can advise you to get acquainted with the relevant GOSTs. The documentation for these standards provides fairly comprehensive information on the rules for manufacturing this product.

Channel 16 – weight 1 meter and dimensions
Channel No. 16 is a type of shaped steel and is a metal product with a cross section in the shape of the letter “P”. The wall height is 16 cm. This metal product is manufactured in two ways: hot deformation and cold bending from strip blanks on roll forming mills.
Hot-rolled products are produced only with equal flange widths; bent products can be either equal or unequal flanges. The visual difference between a hot-rolled profile and a bent one is its clear outer corners.
Types of channel number 16 and their characteristics
Hot-rolled products are produced in accordance with GOST 8240-97 in several versions:
- with a slope of the inner edges of the shelves. Such rolled steel is designated by the letter “U”. Products with a slope of the internal edges of the shelves of 6-10%, having a special purpose, are designated by the letter “C”. The reinforced version of this rolled metal product is designated by the letter “a”. It is characterized by a large width and thickness of the shelf.
- with parallel edges of the shelves. It is designated by the letter “P”; the reinforced version with a larger width and thickness of shelves is marked with the letter “a”. In addition to the “P” series, the following series are produced with parallel edges of shelves: light (“L”) and economical (“E”). The light series is characterized by reduced width and thickness of the shelf, and wall thickness. For economical - smaller wall thickness.
Bent metal products have rounded outer corners and the same thickness of shelves and walls. Equal flange products are manufactured in accordance with GOST 8278-83, unequal flange products - with GOST 8281-80.
The range of rolled products is much wider than the standard list of sizes for hot-rolled analogues, which allows you to select products that are most suitable for the planned application.
Metal products produced by bending have precise dimensions and good surface quality, due to the fact that during the U-shape formation on roll forming mills, minor defects in the strip workpiece are eliminated.
Dimensions and weights of various types of channel grade 16
The standard length of hot-rolled metal supplied to the consumer is 2-12 m, bent - 3-12 m. Bent profile products can be manufactured by continuous or piece bending. In the first case, the strip is bent and then cut into the required lengths. In the second, the strip billet is cut into dimensional pieces, and then bending is carried out.
The weight of channel No. 16 presented in the regulatory documentation is an approximate value, which may differ slightly from the actual one. Regardless of the grade of steel from which the metal product is made, the average steel density of 7850 kg/m3 is used in the calculations for the tables.

Channel 16: dimensions and technical characteristics
Channel 16 is a type of steel product with a U-shaped cross section. Produced by hot rolling or bending.
Hot-rolled products can serve as blanks for cold deformation, the purpose of which is to improve dimensional accuracy and aesthetic characteristics of the surface.
In the production of profile products, carbon steels of ordinary quality and low-carbon steels are used. The manufacturing method and the materials used determine the technical parameters and areas of application of metal products.
Hot rolled channel 16: technical characteristics and applications
Metal products of this group are produced in accordance with GOST 8240-97. There are varieties: with a slope of the internal edges of the shelves (“U”) and parallel edges (“P”), in normal and reinforced versions. In the labeling, reinforced products have the index “a”. With a slope of internal edges in the range of 6-10%, a special series (“C”) is also produced, and with parallel internal edges – light (“L”) and economical (“E”).

By hot rolling at temperatures that exceed the steel recrystallization threshold, products with high strength characteristics are produced.
The visual difference between hot-rolled profile metal products is their clear outer corners; their bent counterparts have slightly rounded corners. Channel 16 made of carbon steel of ordinary quality is used in construction. In particular, it is in demand in regions with high seismic activity or during the construction of facilities whose operation is associated with vibration loads.
Main Applications:
- frame construction (as the main element of the frames of small structures or as an additional element in the construction of large-sized buildings);
- production of marching and spiral staircases;
- reinforcement of foundations;
- installation of a grillage for pile or pile-screw foundations;
- creation of supports for outdoor advertising objects.
If, when installing a structure, an important factor is the good alignment of the channel with other elements along the inner surface, then metal products with parallel inner edges of the shelves are used.
For operation under conditions of increased loads and in areas with cold climates, a hot-rolled channel made of low-alloy steels containing a high amount of manganese, for example 09G2S, is in demand.
Bent channel 16: technical parameters and application
Bent channel is made from hot and cold rolled strips on roll forming mills in two ways:
- continuous – cutting into the required sections is carried out automatically on the bending line;
- piecewise – pre-cut blanks are subjected to profiling.
Differences between bent products and hot-rolled ones:
- lower strength characteristics;
- a richer assortment, the presence of not only equal-shelf, but also unequal-shelf products;
- rounded outer corners;
- higher dimensional accuracy due to correction of small surface defects during the bending process.
The range of bent equal-flange profile is regulated by GOST 8278-83, unequal-flange - GOST 8281-80.

Due to higher dimensional accuracy, bent profile products can be welded without chamfering. A channel obtained by bending is usually not used to create critical load-bearing structures that experience high loads. Typically, these metal products are used for:
- arrangement of frames for facing materials in ventilated facades;
- construction of internal partitions;
- production of heavy equipment.
Bent channels are made not only from “black” carbon steels, but also from corrosion-resistant steels. Stainless steel products are in demand in areas that require resistance to corrosion damage upon contact with aggressive environments and an attractive appearance. Uneven-flanged metal products are usually made to order.

Weight of a linear meter of 16 channels: edge thickness, rolled material, curvature radius in accordance with GOST
GOST 8240–97 contains informative information, standards, tolerances and assortment of hot-rolled channels. Products are made from steel alloys and steels of ferrous and stainless metals in the shape of a U-shaped section. The weight of standard profiles depends on the material, geometric shape, thickness of walls and shelves. Channel No. 16 is considered the most popular in the national economy; the weight of 16 channels per linear meter depends on the conditional parameters.
Channels produced by the hot-rolled method are used in machine tool construction. Due to its strength, rolled products can withstand vibrations and loads of powerful machines. In the car industry, the use of channel 16 GOST 8240 97 allows one to withstand great forces during the acceleration of trains in coupling on rigging humps and when transporting heavy loads.
The mechanical engineering industry receives suitable material for the manufacture of car body frames and chassis. It is used in frame structures and as a base for engine installation. In heavy engineering, individual elements of metal structures are made from channel bars, for example, load-bearing beams of gantry and tower cranes.
When constructing buildings and architectural structures, it is impossible to do without channel 16. The weight of 1 meter fits optimally into structural designs and, with high strength, adds little weight to the finished building. Frames made of this material have a significant margin of safety and have been in use for decades.
Using channel 16:
- when constructing a reinforced frame of walls, partitions, columns;
- for the construction of bridges, crossings, railway crossings, special structures;
- when constructing foundations, reinforced floors, laying sidewalks and driveways with high traffic.
Specifications
According to the production method, channels are divided into hot-rolled steel products for standard purposes and special ones used in heavy industries. Rolled products are produced in sizes of 4-12 meters in length, the blanks are cut into dimensional, multiple-dimensional and non-dimensional. Manufacturing accuracy is indicated by the letters:
- A - high.
- B - increased.
- B - normal.
Material advantages
The main advantage of the profile is its U-shaped cross-section, which results in increased rigidity. Thanks to this, rental is popular in many industries, so the demand for it will never dry up.
Qualitative advantages of the material:
- copes well with various loads - bending, pressure, rupture, compression, withstands axial and lateral loads;
- is universal for use in structures for various purposes;
- relatively light material with high strength properties;
- has low metal consumption;
- under load, the center of gravity shifts to the area of the ends of the shelves;
- The homogeneity of the material obtained using the hot production method eliminates weak points, which is important under mechanical loads.
Disadvantages of hot rolled profiles
The disadvantages include the poor weldability of the material. There are some restrictions when laying hot-rolled channels in structures mounted by welding.
The second disadvantage is reduced corrosion resistance. Hot production does not use aluminum alloys, and finishing technology does not include aluminum coating.
Determining quantities
The properties of rolled products vary depending on the geometric parameters visible in the section. The weight of channel 16 per meter will be different if the basic parameters provided for by GOST change. Classification by these values allows one to judge the method of final processing of the product and the possibility of adjusting elements during installation.
For this purpose, the assortment takes into account conditional values:
- height of the product along the main wall;
- edge width;
- thickness of rolled products and edges;
- internal radius when rounding from a face to a vertical wall;
- face rounding radius;
- distance from the central axis to the surface of the outer wall;
- edge distortion;
- the amount of deflection along the height of the wall section;
- cross-sectional area size;
- moment of resistance and inertia;
- radius of inertia.
Channel categories
The dimensions of the finished products can be non-standard, this is determined by the wishes of the customer. Manufacturing involves the use of rolling mills, where billets are hot rolled and passed between rollers to give the desired shape. Hot rolled channels have greater strength compared to bent products.
Depending on the purpose, rolled products are delivered to the customer with equal flanges or different lengths, and have increased strength, rigidity and other useful qualities. The channel edges are made parallel or with a slight slope. The assortment lists several dozen standard sizes of rolled products, while the product number indicates the height of the main wall (the size between the outer edges, expressed in centimeters).
Depending on their suitability for the task, channels are divided into types:
- with parallel edges (P);
- with shelves made at a certain angle (U);
- with parallel edges, in the economical version (E);
- lightweight design, with parallel edges (L);
- special purpose profiles.
The channel (U) is distinguished by a specific slope of the opposite faces, which are located at a certain angle. In products, the angle between the surface of the shelf and the central wall of the channel should not be more than 10% of the right angle. The weight of a linear meter of channel 16 (U) is 14.2 kg.
Channel speaks about the relationship of products in this category to the group of specialized rental products. This is a rare series and is manufactured only in specially equipped factories. The weight of a meter of channel 16 is 17.53 kg, and with the letter (Ca) a linear meter weighs 19.74 kg.
Products marked (L) and (E) differ in the thickness of the edges and walls, which have smaller values compared to the others. The profile is thinner, light alloys and metals are used, this material is designed to work in light conditions. A linear meter of channel 16 (E) weighs 14.01 kg, the weight of a meter of rolled series (L) is 7.1 kg.
A profile with the letter (P) is a product with standard parallel edges and basic conventional values; it is used under significant loads. There is no rounding of the shelves in relation to the main wall, the angle is 90˚. The weight of a linear meter of channel 16P GOST is 14.2 kg, a product marked 16 (Pa) weighs 15.3 kg.
Measurements of the height and linear dimensions of the profile are made in the plane of the product wall using a caliper. To measure radii, special devices are used.
GOST in regulatory requirements indicates permissible deviations:
- the slope of the internal surfaces of the shelves does not exceed 10%;
- the height of the edge does not exceed the standard value by more than 3 mm;
- the length of the finished product is no more than that indicated in the marking characteristics by 100 mm;
- the level of curvature is within an indicator not exceeding 2% of the length;
- the weight of a linear meter of the finished product does not exceed the standardized value by 2.5-6% (depending on the type), this parameter can be reduced by the customer to 5%;
- the ends of the molding are cut off; a bevel during cutting can reduce the overall length, but do not take it beyond the tolerance limits;
- horizontal and vertical curvature does not exceed 0.2% of the total strip length, the customer can reduce the tolerance to 0.15%;
- Dimensional parameters are measured at a distance of 50 cm from the end of the profile.
Currently, channels are widely used in many manufacturing industries. They are especially indispensable where there is expected to be a large load on both individual parts and the structure as a whole. Construction, metallurgy, mechanical engineering, construction of highways and overpasses - this is a small list of areas of application for rolled metal channels. Durability, low cost, ease of use and transportation make it very popular.

Channel weight 16
Posted by admin on 02.08.2012
So, you are interested in the weight of channel 16. Okay, let's understand its weight. When asked the question how much channel 16 weighs, you need to clarify what exactly is meant.
Usually, the question: how much does channel 16 weigh mean something slightly different, namely: the weight of a meter of channel 16 (otherwise, the weight of a linear meter of a channel, the linear weight of a channel, the specific gravity of a channel, the theoretical weight or calculated, sometimes called the tabular weight of a channel or the weight of a channel according to GOST - it’s all the same thing).
Indeed, as for any other types of rolled metal, for all channel numbers there are standard tabular values for the specific gravity of one linear meter of channel. As for the weight of channel 16, the mass of one meter (theoretical weight) depends not on its shape, but on its height. That is, both the channel 16 with parallel edges of the shelves and the channel 16 with the slope of the internal edges of the shelves weigh the same, with the same height of the channel.
So, the width of the channel is 160 mm. If the height of the shelf is 64 mm, then the specific theoretical weight of channel 16 is = 14.2 kg. Once again, I draw your attention to the fact that this means how much one linear meter of channel 16 weighs according to GOST. The shape of the edges of the channel flanges does not matter; the weight of the channel is the same for both modifications.
So, the width of the channel is 160 mm. If the height of the shelf is 68 mm, then the specific theoretical weight of channel 16 is = 15.3 kg. Once again, I draw your attention to the fact that this means how much one linear meter of channel 16 weighs according to GOST. The shape of the edges of the channel flanges does not matter; the weight of the channel is the same for both modifications.
What is channel 16?
Channel 16 is an ordinary channel, a standard rolled metal product, which has a characteristic U-shaped rolled shape for a channel, but the dimensions of the width of the channel are indicated - they are equal to 160 mm.
That is, a more correct name for a channel of this size can be considered: channel 160 mm wide or channel number 16 (channels are often indicated by numbers, and the channel number is equal to its width in centimeters). However, channel width 16 is not the only feature that describes this type of channel.
It turns out that channels numbered 16 are different. And not at all green, blue, red, but differing in the height of the shelf and the slope of the internal edges. How to understand this?
Types of channel 16 mm
There are two types of 16 mm channel, they differ from each other in the slope of the inner edges of the channel. This can be seen more clearly in the drawing of channel 16.
Channel drawing 16
The first type of channel 16 is a modification called correctly: channel 16 with a slope of the internal edges of the shelves in accordance with GOST 8240-72. Channel 16 diagram in the photo.
Channel drawing 16
The second type of channel 16 is a modification called correctly: channel 16 with parallel flange edges in accordance with GOST 8240-72. Channel 16 diagram in the photo. ..
But that’s not all, as I already said, channel 16 can be made with different flange heights; in the drawing, the height of the channel flange is indicated by the letter c.
Drawing of channel 16 shelf 64
So channel 16, having a width of 160 mm, is produced either with a shelf height of 64 mm. The photo shows a drawing of channel 16, with a slope of the internal edges of the shelves.
Drawing of channel 16 regiment 68
Or with a shelf height of 68 mm. The photo shows a drawing of channel 16, with a slope of the internal edges of the shelves. ..
The story is similar for another type of channel with a flange width of 160 mm, a modification with parallel edges; it also comes in two manufacturing options: with a flange height of 64 and 68 mm.
Drawing of channel 16 with parallel edges and flange height 64 mm.
The photo shows a drawing of channel 16 with parallel edges and a shelf height of 64 mm.
Drawing of channel 16 with parallel edges and flange height 68 mm.
The photo shows a drawing of channel 16 with parallel edges and a shelf height of 68 mm.

The cross-sectional profile of a steel channel is U-shaped. There are several types of channel. They can be distinguished by the letter that is located next to the channel number.
For example: the letter “U” means that the internal edges of the channel flanges are sloped ( GOST 8240-97 ); the letter “E” denotes a series of economical channel bars (GOST 8240-97 ) ; the letter “P” denotes a series of shelf edges that are parallel to each other (GOST 8240-97 ) ; letter “C” special series ( GOST 19425-74 ); the letter “L” means that this channel is light ( GOST 8240-97 ). There are also two types of channels made on a profile bending machine, namely: bent equal-flange channel ( GOST 8278-83 ) and bent unequal-flange channel ( GOST 8281-80 ). Such channels have a rounded cross-sectional shape of the edges. The dimensions of all channel types are given in the tables below.
Steel channels are produced in sizes from 2 to 12 meters. The materials used for manufacturing are: hot-rolled and cold-rolled, carbon, low-alloy, as well as high-quality structural steel. There are channels of regular “B” and increased “B” accuracy.
The use of the channel is different; it has found its application in mechanical engineering and construction. Thanks to its edges, the ability to withstand heavy loads increases. A frame constructed from channel beams can withstand various weather conditions. Currently, it is the main material in the construction of metal structures. Due to its ease of manufacture and relatively low weight, the channel is a leader in civil and industrial construction.
Below are tables of the theoretical weight of steel channels by type.

How to determine the weight of a channel using a table
Typically, the weight of a channel is calculated from tables that indicate the weight of 1 meter of a channel. Knowing the total length of the workpiece, it is easy to calculate its total mass. The parameters of hot-rolled channels produced in our country are regulated by GOST 8240-97.
Channel
Based on the precision of manufacturing (rolling), profiles are distinguished:
- increased accuracy with the letter A;
- increased accuracy, letter B;
- normal accuracy with the letter B.
By manufacturing method:
- hot rolled;
- cold rolled, bent.
By shelf size:
- equal-flange;
- with shelves of unequal size.
By execution:
- regular (solid);
- perforated (lightweight) (aka perforated channels).
According to the material:
The parameters of steel channels produced in the country are regulated by the following GOSTs:
- hot rolled equal flange – 8240-97;
- bent equal flanges - 8278-83,
- bent unequal - 8281-80.
These standards normalize rental parameters and permissible deviations from them, and therefore weight characteristics. For example, hot-rolled equal-flange profiles up to number 16 must have mass deviations within ±3%.
It is worth noting that the parameters (including weight) of a metal profile made in China can vary even within the same workpiece. This should be taken into account when purchasing such a rental.
By release:
- “C” – special custom-made channels, the parameters of which do not correspond to the state standard (Fig. 1, 2);
- “L” - lightweight specimens with parallel edges of shelves, not designed for heavy loads, but used for reinforcing belts of buildings (Fig. 2);
- “E” - economical profiles with parallel shelves, their shelves are thinner than standard ones (Fig. 2);
- “P” – standard with parallel edges of the shelves (Fig. 2);
- “U” – standard with inclined shelves (slope of internal edges) (Fig. 1).
Preparation method
A hot-rolled metal profile (pictured) is smelted in the workshops of metallurgical plants. Cold-rolled, bent (pictured) - bent using rolling rolls in factories from hot-rolled sheet steel. Naturally, they differ in profiles, which means they have different masses of 1 meter of product.
What is the channel number
If we consider a standard U-shaped workpiece, then its height is indicated, expressed in centimeters. For example, channel 20 (or number 20) has a width of 200 mm (20 cm). To indicate the slope of the shelves or series, the corresponding letter is indicated in the marking (see tables 1, 2, 3, 4). The weight of channel 16 and 16a differs due to the different thicknesses of the profile flanges presented.
The profile is available in lengths of 4-12 meters. Most manufacturers produce measuring channels 6 or 12 m long. Thus, if you need a workpiece of a certain length, say 5.8 meters, then it will be difficult to purchase a long size workpiece. Metal profiles are manufactured in custom (unmeasured) lengths (for example, 18 m) and parameters desired by customers.
Weight calculation
Strictly speaking, weight and mass are different physical concepts. So, weight is the force with which the body acts on the suspension, support. And mass already characterizes the inertia of the body. In our case, these concepts coincide.
Below, in fragments of tables from GOST, the weight (mass) of one (linear) meter of channels 10, 12, 14, 16 of various types is given. Other names for this physical characteristic: weight per linear meter (1 meter), calculated, specific or tabular weight.
It is believed that it is made of conventional hot-rolled steel, the density of which is 7.85 units. Since various alloys are used in the production of metal profiles, their practical weight may differ from the standardized table value. For example, the weight of a 12 mm channel presented on the rolled metal market can vary from 3.80 kg/1 m to 14.5 kg/1 m.
Table 1. Parameters of channels 10 to 16 with parallel flanges*
- For the weight of numbers 18 and above, see the full version of the relevant state standard
Table 2. Parameters of channels 10 to 16 standard with sloped internal faces
From the analysis of tables 1 and 2, it becomes clear that the inclination of the shelves does not affect the weight of the profile.
Table 3. Parameters of special channels from 14 to 16
Table 4. Parameters of economical channels 10 to 16 with parallel flange edges
To make it easier to calculate the mass of rolled metal products produced in our country, there are calculators for calculating parameters on websites dedicated to metal structures. They make calculations using the same specific gravity tables. By entering the total length (channel section) of the required profile into it, you get its total weight.
Weights of other types of channels
The nominal density of rolled aluminum metal is 2.7 units; the design characteristics of such profiles are significantly lower than those of their metal counterpart. Therefore, such rolled metal is used much less frequently.
As for the weight characteristics, let’s compare two closely related specimens.
Thus, the weight of hot-rolled channel 10 100x46x4.5x7.6 is 8.59 kg/linear meter (1 meter of profile), and the bent aluminum analogue 100x45x6.0x6.0 has a weight of only 2.884 kg/linear meter (1 meter of profile).
A bent perforated channel is bent from metal 2 mm thick. To make it easier, it has perforation (removal of excess metal) of a given size and frequency. It would not be entirely correct to compare the weight of 1 meter of such a profile with a hot-rolled one. And its purpose is completely different. It is not used as part of the supporting structure of the building, but serves to lay various communications.
The use of channel weight tables is also retroactive. So, knowing the theoretical weight of 1 m of rolled metal (say, the weight of a channel 14), you can check the quality of the material of the metal profiles produced by a particular manufacturer.

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.

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?
The company "Steel-Invest" 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.

Linear weight of channel 16
The channel belongs to shaped rolled products and has a cross-sectional shape resembling the letter P or half of an I-beam. It is made of metal, mostly steel and steel alloys, produced by hot rolling and profiling methods.
Channels are used in almost any branch of human activity where there are high loads on objects, be it a house, a highway or a locomotive. Construction of buildings, engineering structures, heavy industry - channels are used everywhere. Low price, excellent strength, ease of transportation – all this adds advantages to this type of rental.
Channel (U)
One of the most important characteristics of a channel is its mass . The weight of a linear meter of a channel depends on the shape of the beam and the material from which it is made, namely:
- wall thickness and height,
- thickness and height of shelves,
- profile length,
- metal density.
16 (U) | 14,2 |
Channel (C)
A special channel with the letter C after the number on the stamp makes it clear that this is a special series channel. Not all manufacturer dealers sell such rentals, since the most popular and in demand series are U and P.
The channel number indicates its width . For example, for channel 16 it is 160 mm between the outer edges. And the length of the channels ranges from 2 to 12 meters. Moreover, there are both non-standard and multiple sizes; they can be classified into one of three groups:
- measured length,
- multiple measured length,
- of unmeasured length.
16 (C) | 17,53 |
16 (Ca) | 19,74 |
Channel (E)
Channels are produced in two main ways - the hot rolling method on special machines and the bending method. The channel formed by bending does not have sharp corners, the joints of the wall and shelves are slightly sloping both outside and inside.
The profile of the hot roller is different, carried out in accordance with GOST 8240-97, it has specifically specified radii of rounding and the shape of the channel flanges. Such channels can be either with shelves tapering towards the outside or with straight ones.
BrandWeight of 1 meter, kg16 (E) | 14,01 |
Channel (P)
This series of channels are standard massive shelves and a wall; such a channel is used for heavy loads and high reliability requirements.
Due to the high strength properties that the U-shaped profile has, it is actively used in construction, reinforcing interfloor and roofing floors, additionally strengthening critical areas where the main load is supported by large I-beams, etc.
BrandWeight of 1 meter, kg16 (P) | 14,20 |
16 (aP) | 15,30 |
Channel (L)
If there is a need for a beam longer than 12 meters, then manufacturers, in principle, have the ability to produce such a profile. This may be in demand when reinforcing the foundation of a multi-story building or roofing structure.
But the complexity of transportation and the wait for custom-made channels are not always worth it, so if the designer or drafter insists on using channels longer than 12 meters, it makes sense to reconsider the project and make changes.
Just for structures that are not very loaded , such as roof slabs, but still require high frame strength, a 16L channel can be used . Its weight is less, it is cheaper and is used for areas without strong requirements for static and dynamic loads.

Linear weight of channel 10, 12, 14, 16, 18, 20, 22, 24u: weight calculation, GOST 8240-97
Modern science distinguishes between concepts such as weight and mass. This happens primarily because weight is a strength characteristic, i.e. a measure of impact on a support or suspension. Mass, on the contrary, is a measure of the inertia of a body. We are writing all this so that while reading this article you will not have any questions about what is the difference between the weight of a channel and its mass. For simplicity, we consider here only those situations where these two parameters are equivalent.
In the case of profiles, the mass depends on the following parameters:
- Forms;
- Metal;
- Sizes.
Shape and dimensions
Speaking about the shape, it is necessary to clarify that there are several types of profiles, for example, classic and perforated.
Metal structures can be made not only from steel, therefore, when talking about other alloys, this will be indicated separately. We are clarifying this point, since the weight of channel 12 made of aluminum will be several times lower than when steel is used.
Weight of channel models
In the usual case, the mass of a profile is calculated quite simply, but only if its shape is simple. Those. We are considering an equal-flanged product, the internal edges of the walls of which are located parallel to each other.
There are also unequal profiles, for which the calculation of mass is somewhat more complicated, but the most difficult option is the inclined edges of the internal walls.
This product turns out to be very massive, but this is compensated by increased strength due to the large volume of metal.
The weight of channel 10 can vary from 3 to 12.7 kg depending on its dimensions. In this case, such a large spread is ensured by different wall heights. It starts at 40 mm and can reach 160 mm, resulting in a very deep profile. The thickness also does not remain constant and varies from 2 to 6 mm.
If we consider all the numbers of the bent profile, then we can say that the channel with the h:b:s ratio of 25:26:2 mm has the minimum mass. The weight of this profile barely exceeds 1 kg. On the other side of the size line there is number 41, which can be presented in the form of a similar ratio of 410:65:6 mm and the weight of just one meter will already be 24.38 kg.
A higher channel number does not mean that the product will be heavier. The weight of channel 20 will be less than that of number 21 only if the dimensions of the walls and the thickness of the product are the same, otherwise even number 20 will be able to bypass the 21 profile.
The mass of hot-rolled profiles starts from 4.84 kg for the 5U product, the dimensions of which can be represented as 50:32:4.4 mm, and the length is 1 m. With a wall height of 40 mm and the presence of a slope of the internal edges, the weight is 48.3 kg per 1 m This is due to the fact that the metal consumption for such a channel is very large, and its dimensions are 400:115:8 mm.
Metal
Usually, when they talk about the tabular value of the mass or weight of profiles, examples of which we gave in the previous paragraph, they mean some abstract steel having a density of 7.85 units and a product length of 1 m. In reality, the situation is somewhat different, since the most different alloys.
One of the interesting options for various unloaded structures is aluminum. This is a fairly common silvery-white metal today, the density of which is 2.7 units. Obviously, the weight of channel 14 made of such material will be much lighter than steel; another thing is that creating such large structures from aluminum is not always advisable.
As a structural material, aluminum is very attractive not only because of its low weight, but also because it can be easily stamped and does not require any additional protection. Of course, during the technological process, the production of profiles from this metal is accompanied by various procedures that make it possible to slightly increase the strength of the product.
Steel channels
On the other hand, steel is used even more often than aluminum, and the most common options are carbon and low-alloy varieties. The quality of carbon steels is determined by the presence of impurities in them. The most dangerous are sulfur and phosphorus. Sulfur causes the metal to become red brittle, and phosphorus causes brittleness. For ordinary steel, these components cannot exceed 0.05%.
Within such a group, the mass of 1 m3 changes insignificantly, so the influence of impurities on the weight of the channel can be neglected. In this case, the metal marking “St” is used. A higher quality variety already has the designation “Steel”, and the S and P content is less than 0.035%. There are two more varieties of such alloys, high quality and special quality, in which the proportion of harmful impurities is less than 0.025% and 0.015%, respectively.
For high quality steel, the marking “A” is used at the end of the mark, and for higher quality, “W”.
The type of steel affects the weight of a meter of profile. For example, the weight of a channel 16 made of carbon steel will be different from the result obtained when using an alloy alloy.
Alloy steel is an alloy that, in addition to basic impurities, contains a number of elements that are introduced in certain quantities. These are alloying additives, the role of which is chosen from chromium, copper, bound nitrogen, nickel or vanadium. All alloy steels are divided into 3 categories:
- low alloy;
- medium alloyed;
- highly alloyed.
In the first case, we are talking about only 2.5% impurities, in the second they can be up to 10%, and highly alloyed compounds often have 50% impurities.
To summarize, we note that we have considered most of the factors that influence the weight of the channel. It should also be noted that when weighing a batch, it will be necessary to take into account small deviations caused by various errors, which is clearly stated in the relevant state standard.

Weight of hot rolled channel. Channel assortment GOST 8240-89
GOST channel - metal beams (hot-rolled profiles), in cross-section resembling the letter “P”.
The channel flanges are located on one side of the wall (unlike z-profiles, in which the flanges lie on opposite sides of the wall). They can be of different lengths, sizes, types, and inclinations. Therefore, before you buy a channel, you need to know exactly all the parameters that are necessary.
Hot-rolled channel GOST 8240-89 is widely used in the manufacture of buildings from metal structures.
The assortment of steel channels is an assortment of shaped rolled products, the cut of which is a continuous metal profile of a U-shaped section. Profile number P5-P24 is manufactured with dimensions in accordance with GOST 8240-89 (see the table of correspondence between the size and weight of the channel) from steel of various grades.
Hot-rolled steel is used to impart rigidity and stability to the structure in which its standard dimensions are used. Channels work well in bending and absorb longitudinal loads, thereby increasing strength and reducing the weight of the structure in the total weight.
Channels of various sizes are used for the manufacture of frames of metal structures, beams, columns, stairs.
What is the weight of the channel?
Study the correspondence table below “Channel. Size-mass.” This table shows the correspondence of channel dimensions and weights according to series P DSTU 3436-96 (GOST 8240-97).
The values for the weight of 1 m of channel and the quantity per ton in the table are given for reference, because calculations were made using the nominal dimensions of the width, length and thickness of the shelves. In practice, there are no ideal sizes. In accordance with GOST, deviations are allowed for each value, which in total can give up to a 5% increase in the actual weight of the channel. Rolled products with a weight less than the calculated one are rare.
The size and type of channel can be recognized by its marking, the number in the designation is the distance between the outer edges of the edges of the product (size h), measured in centimeters, the letter P indicates that the shelves are without slope and are parallel to each other if the edges are located at an angle , then the designation has the letter U. There are also channels in the markings of which there may be another letter, which indicates that this product is positioned as a light (type L), economical (type E) or special (C) model.

About the weight of the channel
Structures are made of steel and other metals. If it is made of aluminum, then the weight of product No. 12 will be less than that of a model made of steel.
If the profile shape is simple, then it is not difficult to calculate the mass of the product. For consideration, let’s take a product with equal shelves, which has a parallel arrangement of the inner edges of the walls.
There are also models that have profiles with unequal flanges, for which it is more difficult to calculate the mass.
In order to make correct calculations of the load experienced during the construction of supports and structures, you need to know the mass of the product. You don't have to put the entire product on the scale. If you know just the weight of 1 m, then you can easily calculate the mass of the total footage.
About the mass of channel 10
Depending on the size of this product, its weight can be 3-12.7 kg. The difference in numbers is due to different wall height parameters. In this case, the height of the walls can be 40-160 mm. As for the thickness of the product, it is 2-6 mm.

For a product with dimensions 30:25:3 mm, the weight will be 1.61 kg/m.
For a model with parameters 32:25:2 mm, the weight will be 1.17 kg/m.
About calculating the weight of the channel
The weight of the goods is calculated using the nominal parameters of shelf thickness, length, width. Nowadays it is difficult to find rolled products whose weight is less than the calculated one.
According to GOST, deviations in the thickness, length, and width of the shelves are permissible. In total, they are capable of increasing the actual weight of rolled metal by up to 5%.
About bent profile
The mass of the 25:26:2 mm channel is just over a kilogram. For No. 41 the mass will be 24.38 kg.
A high product number does not mean that the product will be heavier. For example, mass No. 20 may be less than mass No. 21 if the thickness and parameters of the walls of the products are the same.
The mass of the hot-rolled profile is 4.84 kg for model 5U. The length of such a product is 1 m, dimensions 50:32:4.4 mm. This channel has a wall height of 40 mm.
To determine the type and size of a product, a number in the designation or marking is used. If the edges of a product are located at an angle, then they are marked U. If the shelves do not have a slope, then they are marked P.
You can also find the following markings: C indicates a special model, E - economical, L - light.
If you set the dimensions of the width, height of the shelves, and the total length of the workpiece, you can also calculate the weight of the product.
When choosing products, you should choose a good quality product. It must withstand corrosion well and be durable.
To package hot-rolled profiles, bundles or bags are used. Their weight can be 4.5-8 tons. In two places, each pack is tied with steel tape. Tags are attached to opposite sides of the package indicating the steel grade, GOST, package weight, heat number, batch number.
For transportation between batches, wooden blocks are placed. This helps prevent damage to the surfaces of goods that may occur when the goods slide. In addition, wooden blocks provide clearance between batches of goods.
Steel is often used to make goods. The quality of steel is determined by the presence of impurities in it. Ordinary steel should contain no more than 0.05% sulfur and phosphorus. It is these elements that are responsible for the fragility and red brittleness of the metal.
