Channel 14 - characteristics according to GOST and assortment
Channel number 14 is a type of steel shaped metal product produced by hot rolling or bending. The cross section is U-shaped, the wall height is 140 mm, the shelves can be equal or unequal. Hot-rolled equal-flange channel 14 is produced in accordance with GOST 8240-97.
The range of bent equal flange products corresponds to GOST 8278-83, bent unequal flange products - GOST 8281-80. In the production of channel 14 for ordinary use, carbon steels of ordinary quality of different degrees of deoxidation are used, for example St3sp, St3ps, St3kp, and high-quality structural unalloyed steels.
Metal products intended for use in difficult operating conditions, including under alternating loads, are made from low-alloy steels.
Types of channel 14, main characteristics
The marking of hot-rolled shaped steel with a U-shaped profile, manufactured in accordance with GOST 8240-97, indicates the wall height, expressed in centimeters, and a letter designating the series. The products have several types of execution.
- With a slope of the internal edges of the shelves (U) . The slope angle lies within 4-10%. These products are widely used in construction for reinforcing foundations, constructing trusses, and installing floors. The products can be used in the creation of load-bearing and non-load-bearing metal structures, and the construction of fences. Rolled products made from low-carbon steels are well weldable, therefore they are used in both welded and prefabricated metal structures.
- With parallel inner edges of the shelves (P) . The products are used in construction, machine tool manufacturing, and mechanical engineering. The weight of 1 m of channel 14P series does not differ from the weight of rolled products of series 14U.
- Economical series (E) . It has parallel internal edges of the shelves; it differs from the P series in its thinner wall.
- Light series (L) . Channel 14 differs from the P series in having reduced flange dimensions and wall thickness, and therefore a smaller cross-sectional area and a weight of 1 meter. L series shaped steel is used in metal structures not used under high loads.
- Special series (C) – 14С and 14Са . It has a slope of the internal edges of the shelves. Products marked 14Са have a more massive cross-section compared to rolled products 14С.
Bent equal-flange channel with a wall height of 140 mm is produced in accordance with GOST 8278-83, unequal-flange - in accordance with GOST 8281-80. For the manufacture of these products, steel can be used - carbon steel of ordinary quality and high-quality, low-alloy, alloy (corrosion-resistant, heat-resistant, heat-resistant).
The standard length of channel rods 14 supplied for sale is 2-12 m. Consumers can order a batch of longer lengths. To increase the corrosion resistance of metal products made from “black” steels, they are galvanized or coated with a paint layer. Galvanizing not only provides barrier protection to the base metal, but also protects it from electrochemical corrosion.

channel 14
Channel 14 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 140 mm.
That is, a more correct name for a channel of this size can be considered: channel 140 mm wide or channel number 14 (channels are often indicated by numbers, and the channel number is equal to its width in centimeters). However, channel width 14 is not the only feature that describes this type of channel.
It turns out that channels numbered 14 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 14
There are two types of channel 14, they differ from each other in the slope of the inner faces of the channel. This can be seen more clearly in the drawing of channel 14.
Channel drawing 14
The first type of channel 14 is a modification called correctly: channel 14 with a slope of the internal edges of the shelves in accordance with GOST 8240-72. Channel 14 diagram in the photo.
The second type of channel 14 is a modification called correctly: channel 14 with parallel flange edges in accordance with GOST 8240-72. Channel 14 diagram in the photo. ..
channel drawing 14
But that’s not all, as I already said, channel 14 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 14, having a width of 140 mm, is produced either with a shelf height of 58 mm. The photo shows a drawing of channel 14, with a slope of the inner edges of the shelves.
channel drawing 14
Or with a shelf height of 62 mm. The photo shows a drawing of channel 14, with a slope of the inner edges of the shelves. ..
The story is similar for another type of channel with a flange width of 140 mm, a modification with parallel edges; it also comes in two manufacturing options: with a flange height of 58 and 62 mm.

The photo shows a drawing of channel 14 with parallel edges and a shelf height of 62 mm.

Channel thickness 14?
The thickness of the channel 14 depends on its modification and in practice, when we talk about the thickness of the channel, we must understand that we are discussing the thickness of its wall.
In the drawings of channel 14 given above, at the beginning of the article, we see that its thickness is measured (dictated by GOST) in two places.
This is the wall thickness of the wide channel flange (what we call channel width 14) - S and the wall thickness of the narrow channel flange (what we call channel height 14) - t. So, as for the specific thickness values of channel 14, GOST defines the following values.
For channel 14 with a slope of internal edges, a width of 140 mm and a height of 58 mm, the thickness of the channel is determined by two values: S = 4.9 mm, t = 8.1 mm.
For channel 14 with a slope of internal edges, a width of 140 mm and a height of 62 mm, the thickness of the channel is determined by two values: S = 4.9 mm, t = 8.7 mm.
For channel 14 with parallel edges, width 140 mm and height 58 mm, the thickness of the channel is determined by two values: S = 4.9 mm, t = 8.1 mm.
For channel 14 with parallel edges, width 140 mm and height 62 mm, the thickness of the channel is determined by two values: S = 4.9 mm, t = 8.7 mm.
That is, as we see, despite the different shapes of the channels 14, they are quite well unified, which is convenient both in the manufacture of structures from the channel and in estimating its weight.
However, ATTENTION!!! When we call the thickness of a narrow wall for channel 14 with a slope of the internal edges of the flanges, then the thickness t turns out to be a conditional, average value chosen approximately in the middle of the flange edge.
Closer to the end of the narrow flange, the thickness of the channel decreases, and closer to the wide flange it increases. Look at the drawing of channel 14 - it’s clearly drawn there.
Channel area 14?
When talking about the area of this type of rolled metal, we can discuss either the cross-sectional area of the channel 14 or the surface area of the channel 14. People often ask why the surface area of the channel is needed? It seems that in the manufacture of structures it is not very important, is not taken into account in calculations and is not included as a parameter in formulas.
This is true, but one of the final stages of manufacturing structures from channel 14 is painting the metal structures with paint to protect them from corrosion. Channel 14 is no exception here. And in order to design and plan work on the manufacture of metal structures, we will need to draw up an estimate for painting in advance.
For this purpose, the surface area of the channel (1 linear meter) is useful in order to calculate the painting area of the channel. The area of channel painting, in turn, is related to the paint consumption per unit area and the timing of the work.
So you can calculate the painting area of channel 14 based on tabular data according to GOST - channel surface area.
But, much more often, we need the cross-sectional area of the channel 14. I note that depending on the angle at which the cross-section of the channel is made relative to its axis, we will get completely different values of the cross-sectional area. In practice, usually only one type of section is used in calculations and formulas - transverse. When the section is made at an angle of 90 degrees to the channel axis. So, the cross-sectional area of the channel 14 depends on the specific modification of the rolled product.
For channel 14 with a slope of internal edges, a width of 140 mm and a height of 58 mm, the cross-sectional area of the channel is = 15.6 sq.cm.
For channel 14 with a slope of internal edges, a width of 140 mm and a height of 62 mm, the cross-sectional area of the channel is = 17 sq.cm.
For channel 14 with parallel edges, width 140 mm and height 58 mm, the cross-sectional area of the channel is = 15.6 sq.cm.
For channel 14 with parallel edges, width 140 mm and height 62 mm, the cross-sectional area of the channel is = 17.0 sq.cm.
Center of gravity of channel 14
Let's look again at the drawings. The center of gravity of a channel is a value that also depends on the specific modification (shape) of the channel. So, the center of gravity is distinguished for all types of channels, that is, if we have 4 different shapes of a channel, then for each of them the center of gravity will be different. Let's look at the drawing and extracts from GOST.
Here, again, is our channel 14 with a slope of the inner edges of the shelves. In the drawing at the beginning of the article, the center of gravity of the channel is indicated by the letter - Z0. Can you see it well? For channel 14, width 140 mm and height 58 mm, the center of gravity is equal to - 1.82 cm. And, for channel 14 with height 62 mm, the center of gravity will be equal to - 2.04 cm.
Here again is our channel 16 with parallel edges of the shelves. In the drawing at the beginning of the article, the center of gravity of the channel is indicated by the letter - Z0. Can you see it well? For channel 16, width 160 mm and height 64 mm, the center of gravity is equal to - 1.97 cm. And, for channel 16 with height 68 mm, the center of gravity will be equal to - 2.19 cm.
Channel radius 14
The channel has several radii, the value of which is also determined by GOST. R and r that are important for calculations and formulas are identified . See the drawing of the channel of the corresponding type. Now the tabular values of the channel radius for each of its modifications.
For channel 14 with a slope of the inner edges of the shelves, a width of 140 mm and a height of 58 mm, the radius R and r are respectively equal to 8.0 and 3.0 mm. And, for channel 14 with a height of 62 mm, the radius R and r are respectively equal to 8.0 and 3.0 mm.
For channel 14 with parallel flange edges, width 140 mm and height 58 mm, the radius R and r are respectively equal to 8.5 and 4.5 mm. And, for channel 14 with a height of 62 mm, the radius R and r are respectively equal to 8.0 and 4.5 mm.
Channel gyration radius 14
The radius of inertia of a channel is one of the quantities that depends not only on its shape, but also on the selected coordinate axis.
As we see in the photo of the drawing of channel 14, in mechanical engineering and the design of metal structures they mainly use 2 axes: XX and YY, where XX is the axis passing through the middle of the wide flange of the channel, perpendicular to the plane of the flange, and the YY axis passing through the center of gravity of the channel parallel to it wide shelf. So, the values of the radii of inertia of the channel 14 for different axes are designated according to the name of each of the axes: Rx and Ry .
For channel 14 with a slope of the inner edges of the shelves, a width of 140 mm and a height of 62 mm, the radius Rx and Ry are respectively equal to 5.60 and 1.70 cm. A, for channel 14 with a height of 62 mm, the radius Rx and Ry are respectively equal to 5.66 and 1.84 cm.
For channel 14 with parallel flange edges, width 140 mm and height 58 mm, the radius Rx and Ry are respectively equal to 5.61 and 1.81 cm. A, for channel 14 with a height of 62 mm, the radius Rx and Ry are respectively equal to 5.68 and 1.96 cm.
Channel weight 14
When asked the question how much channel 14 weighs, you need to clarify what exactly is meant. Usually, the question: how much does channel 14 weigh mean something slightly different, namely: the weight of a meter of channel 14 (otherwise, the weight of a linear meter of 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 14, the mass of one meter (theoretical weight) depends not on its shape, but on its height.
That is, both the channel 14 with parallel edges of the shelves and the channel 14 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 140 mm. If the height of the shelf is 58 mm, then the specific theoretical weight of channel 14 is = 12.3 kg. Once again, I draw your attention to the fact that this means how much one linear meter of channel 14 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 140 mm. If the height of the shelf is 62 mm, then the specific theoretical weight of channel 14 is = 13.3 kg. Once again, I draw your attention to the fact that this means how much one linear meter of channel 14 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.

The weight of the channel is 14 per linear meter. Linear weight of channel - calculation and dependence
Channel 12 with a width between the outer edges of the shelves of 120 mm is a relatively light and very durable element used in many sectors of the economy. It is actively used in machine tool building, mechanical engineering, as supporting structures in columns, as a load-bearing element in floors, etc.
With a relatively small weight of steel channel 12 (slightly more than 10 kg), the load it can withstand is several times greater than that which is permissible for a square pipe of the same weight. This explains the popularity of the widespread use of such beams, as well as the manufacturability, produced in the following types:
- hot rolled on section machines,
- curved on profile bending machines.
Channel 12 is produced in four series , depending on the shape and location of the profile elements relative to each other - with a Y-shaped slope of the internal edges of the shelves, with parallel edges of the shelves, an economical series, a light series.
The production of channels is regulated by the following standards:
- GOST 8240–97 (hot rolled),
- GOST 19425–74 (special),
- GOST 8278–83 (equal flange bent),
- GOST 8281–80 (unequal bent).
Channel(U)
For the manufacture of channels, mainly the following steel grades are used: St3ps, St3sp, as well as low-alloy steel 09G2S. These steels have proven themselves to be excellent, including their reasonable cost, which makes it possible to produce channels with a low selling price.
Thanks to its U-shape and small dimensions, the channel is actively used where it is impossible to use I-beams due to design features or small dimensions into which the I-beam does not fit. Moreover, the strength of the channel is almost as good as the more massive and, accordingly, expensive I-beams.
BrandWeight of 1 meter, kg| 12 (U) | 10,40 |
Channel (P)
In the carriage building and automotive industry, channel bars are actively used for their strength characteristics and low weight. For these industries, special series of channels are also produced, which are marked with the letter “C” after indicating the size of the channel.
In addition, GOST requires that manufacturing accuracy be indicated when marking. determine whether the manufacturer of the product adhered to high or normal accuracy by the designation A, B (high) or C (regular) on the right side of the stamp.
The channel with parallel flange edges differs from the previous series. In it, the planes of the inner edges of the shelves and walls are perpendicular to each other throughout.
The quality of such a channel is of particular importance , since in defective products from a manufacturer that does not comply with GOST requirements, the angle between the flange and the wall may be acute, which will negatively affect the resistance to torsion and lateral loads acting on the channel.
BrandWeight of 1 meter, kg| 12 (P) | 10,40 |
Channel (L)
The channel, designated after the number by the letter “L”, is a lightweight version of the U-shaped beam . It is also used in a variety of areas:
- roofing frames,
- ceilings of underground structures,
- bridge trusses,
- housing construction, etc.
Due to lower metal consumption, the weight of the 12L channel is less and the price is lower . By using this channel in elements of metal structures with a lower load, but more stringent weight requirements, the customer of the design work saves significantly.
Sometimes, the use of a lightweight version is necessary, because the weight of a linear meter of such a channel is almost two times less and, according to GOST 8240–97, is only 5.02 kg.
BrandWeight of 1 meter, kg| 12 (L) | 5,02 |
Channel(E)
Channel shelves of the “E” series are thinner. Due to the saving of metal, the cost of such rental is also reduced. Where it is intended to use such a channel, the load may be less, then the use of an economical series is advisable.
The ability to withstand heavy loads with a small cross-section, low cost and mass availability has ensured the popularity of the channel in construction. Not a single low-rise or high-rise building project can be completed without the use of this type of rental. U-shaped beams are also used when constructing a foundation, to reinforce and strengthen a concrete structure.
