How much does Channel 20p weigh?

What is the weight of channel 20?

Channel No. 20, which is one of the standard sizes in the assortment according to GOST 8240-97, is one of the most popular types of channels in construction . Not very heavy (the weight of channel No. 20 is a little more than 18 kg per linear meter), this type of rolled steel is widely used in the construction of floors, columns, engineering structures, industry, automotive and carriage building.

The standards define two forms for this channel - this is a form with a flange slope, a Y-shaped form, and a U-shaped channel. Despite the obvious differences between these products, their weight is almost the same (discussed in more detail in the table below), so the choice between them is determined by the requirements of the design work. There are also three more series of this channel, these are:

• type E (economical),
• type L (lightweight, lower design load),
• type C (special).

It must be remembered that the E and L type channel is structurally designed with parallel flange edges.

If you would like to study the specifications and assortment for this type of channel, then GOST 8240-97, or the outdated GOST 8240-89, has complete information on its characteristics.

Channel with a slope of the internal edges of the shelves (U)

The shape of a Y-shaped channel, despite its name, does not represent the letter U in cross-section. It is also called a channel with a slope of the inner edges of the shelves, which is much closer to the essence. Its shape is very similar to a U-shaped channel, but the main difference is in the different angles of inclination of the internal edges of the shelves, regulated by the corresponding GOST.

Moreover, the slope can only be within a given range - this is 4-10 degrees. And number 20 means that the distance between the outer sides of the shelves is 200 mm, in fact, this is the width of the product, and the length varies widely, because Each manufacturer produces channels with a length of either 4 meters, or a multiple of this number, or a special length, according to the client’s order.

BrandWeight, kg

20 (U)	18,40

Channel with parallel flange edges (P)

Channel 20P also refers to hot-rolled channels with parallel flange edges. Unlike the U-series, the thickness of the shelves of this product is practically unchanged and is equal to the same value as that of the wall . This makes the product heavier, because the shelves become much more massive. But, nevertheless, this type of rolled product finds its application, and the load and resistance characteristics are slightly higher.

BrandWeight, kg

20 (P)	18,40

Channel with parallel flange edges (E)

As the name suggests, this series of channels was added to GOST for projects where large cost savings are required, but at the same time, the loads on the floors and load-bearing structural elements remain serious. Otherwise, it would be more advisable to take a channel with a lower number and cost.

BrandWeight, kg

20 (E)	18,07

As we can see from a comparison of these channels 20P and 20E, they are very similar, but in the economical series the weight of each meter is 0.3 kg less and there are some differences in the wall thickness and the radii of rounding the corners between the wall and the shelves.

Channel with parallel flange edges (L)

This type is much lighter and not as massive as 20P or even 20E. Compared to the U-shaped channel, its wall is almost one and a half times thinner, and the weight is almost two times lower, only 10.12 kg, which is why this series is called light.

BrandWeight, kg

20 (L)	10,12

Special channel (C)

And finally, we just have to consider a special type of channel, which differs from others in all respects - a different shape, wall thickness, flanges, rounding radius and weight. By the way, the weight of 20C is the largest of all - it is 22.6 kg. This channel is heavier than two 20L combined.

Such specific characteristics of channel 20C are explained by the fact that this rolled product is used in such branches of mechanical engineering where increased strength and load resistance are required from the product, in particular, in the automotive industry.

BrandWeight, kg

20 (C)	22,6

Channel for carriage building (20V)

You will not find this type of channel in GOST 8240-97, but it is in other standards, for example, in GOST 5267-90. This channel is produced for carriage building in three types:

There are differences between them, for example, the 20V-1 channel has better characteristics and is more massive than a simple 20V, and 20V-2 is even more durable and can withstand heavy loads. All channels of the car-building series are heavier in weight than other No. 20, including 20C.

This is understandable; in railcar construction, the parameter of resistance to static and dynamic loads, resistance to torsion and deformation with a large margin of safety for operation in difficult conditions comes first. In low-rise construction or the automotive industry, the tasks are different, and accordingly, metal structures are needed with different parameters.

BrandWeight, kg

20 (V)	22,63
20 (B-1)	25,77
20 (B-2)	28,71

Channel marking

To differentiate the assortment of channels, a simple and concise channel marking system was developed. During the production process of rolled products, markings are stamped directly onto the finished products; let’s take a closer look at this inscription and the principle of its composition:

• number,
• type,
• precision manufacturing.

The first item is a number equal to the distance between the outer edges of the shelves. For example, if the distance between the edges is 200 mm, then the channel number is 20, if it is 160 mm, then 16, etc.

The second entry in the name is its type or purpose. All types of channels are divided into several categories and are designated by a letter code. We looked at them above - these are P, U, E, L, S, V. Depending on the type, the profile of the channel and its other characteristics differ.

The third entry is the manufacturing accuracy class of a given batch of rolled products by the manufacturer, there are three of them:

• A - tall
• B - increased,
• B - ordinary, something that the Quality Control Department did not classify as the first two classes.

Accuracy parameters are taken from changes in channels and comparison with standards - characteristics of length, wall height, flanges, product weight.

Assortment of channels - table of sizes, marking according to GOST

Such a common element of many supporting structures as a channel is a U-shaped profile that can be made of various types of steel, including stainless steel. Channels can differ not only in size (a special table is used to determine each of them), but also in manufacturing technology.

We understand the range of channels

Channels are produced using cold-rolled and hot-rolled technology. U-shaped metal profiles of different brands also have differences in the design of the shelves. Thus, there are channels, the inner edges of the shelves of which are parallel to each other, as well as products, the shelves of which are made with a certain slope on the inside.

However, no matter what version the shelves are made in, the entire range of profiles with a U-shaped section is distinguished by high rigidity, combined with low weight. It is these properties that make it possible to successfully use channels of any size for the manufacture of highly loaded structures for construction and any other purposes.

The main advantages of U-shaped profiles include:

• high strength, ensuring resistance to bending loads;
• the ability to successfully withstand not only bending, but also multidirectional loads (rupture, compression, etc.);
• high resistance to shock loads, which can lead to mechanical damage to the structure (a metal channel, which is made with high quality and in accordance with GOST, has practically no weak points in its design that can cause its destruction from various loads).

Parameters of a channel with a slope of the internal edges of the shelves

Marking

If you look at the range of channels, you can see that it includes metal profiles with a wide range of sizes.

With such a variety of options offered, it is very difficult to choose exactly the brand of channel that will be optimally suited for solving a particular problem. Naturally, the manufacturers took this point into account.

To designate their products, they use markings, which can be used to get a fairly complete picture of the characteristics and dimensions of the U-shaped profile.

Parameters of a channel with parallel flange edges

Markings that comply with GOST 8240-97 include both digital and alphabetic designations. The first number in the designation is the main characteristic; it corresponds to the size of the channel, that is, the distance between its flanges.

By the letter in the marking you can determine what type the channel is.

These can be products in which the internal edges of the shelves are made with a slope or are parallel to each other (“U” and “P”, respectively), metal profiles of economical (“E”) or light (“L”) type, special purpose (“S” ).

If you need to know all the other dimensions of a channel of a certain brand from the assortment, then for this there is a special table in which they are indicated. The choice of a product of a certain brand is made depending on what kind of loads the structure for which it is planned to be used will be subjected to.

some features of choice

The range of channels, of course, is significantly inferior in variety to the range of angles, but this does not prevent the selection of a product of the required dimensions and characteristics to solve a specific design problem.

When choosing a specific brand from the assortment, you should be guided by the following rule, which is relevant for products of any profile: having decided on the type of channel that meets your requirements, you should include in the specification for the drawing the brand that is located closer to the beginning of the table.

The assortment, in which various types of channels are presented in table form, allows you to determine not only their sizes, but also a number of other important parameters:

• linear meter weight;
• cross-sectional area;
• axial moment of inertia;
• axial moment of resistance;
• radii of inertia.

The last three parameters are calculated relative to the central axis of the channel section.

It is very important to choose those brands of channels whose mechanical characteristics are not lower than the calculated ones by more than 5%. If this condition is not met for the selected brand of product, then it is better to take a channel one number higher.

Manufacturing channel 20

Following GOST 8240-97, 20mm channel is produced only at enterprises. However, when purchasing, you should personally verify this and check the product for a certificate of conformity. Otherwise, huge defects may arise during the operation of buildings or the structure may completely collapse.

The production is mainly based on alloys with the addition of structural carbon and low-alloy steel. Such alloys have special grades st2ps and st3sp, respectively. Alloys have many different metals in their chemical composition (for example, aluminum).

Channel assortment 20

The range of channels is large and has special letter designations in order not to be confused and to easily recognize the production method:

1. “P” - channel 20P has parallel edges of the shelves.
2. “U” - the internal edges of the shelves are located at an angle.
3. “C” is a special channel. GOST does not define the parameters of this product. Since such channels are made to order, and the client himself sets the parameters he needs.
4.  "L" - light. Manufacturing is carried out in accordance with GOST, but only light metals will be added during the production process.
5. “E” is an economical channel. Less metal is used in production.
6. “B” - such a channel is used only for the construction of cars or cars.
7. “T” is a metal product that has found its application for tractors.

All channels are produced in several ways:

1. Hot rolling method.
2. Cold rolled or bent channel.
3. Special method.

The channel 20 can be produced by hot rolling. The production process is described in more detail in GOST 8240-97.

Channel dimensions 20

Based on the above, the manufacture of channel 20 occurs in compliance with GOST. The standard size of channel 20 is 20 meters. But you can always order a channel with the required parameters. Such a channel is indicated by a special marking in the form of the letter “C”.

Technical characteristics of channel 20

Channel weight 20, 10, 16

The strength and durability of the metal explains its incredible popularity.

Products made from it are used in almost all types of modern construction, ranging from banal advertising structures to large-scale structures (skyscrapers, statues, bridges, etc.).

Today, metal structures are produced in different shapes and sizes (beams, pipes, angles, channels, etc.). Our publication is devoted to the latter, or rather to their features, including the weight of the channel 20, 10, etc.

Concept, types

Channels are recognized as the most popular building elements due to the following:

— reliability;

— efficiency;

- simple installation.

Most often, the channel is represented by a profile in the form of the letter “P” in cross section. Such products are made from steel or aluminum. GOST provides for the production of bent or hot-rolled products. The first one may differ in size and shape. Hot-rolled steel has a slope of at least 10% for internal flanges.

There are differences in these types of profiles in terms of strength (regular and increased). It is quite easy to distinguish a bent product from a hot-rolled product; you just need to pay attention to the corners of the structure. Clear roundness is a distinctive feature of the bent analogue.

The high degree of strength of this type of metal structures determines its active use in lightweight units.

About labeling

The type and size of the channel are reflected in the marking. The distance between the outer edges of the channel shelves is a figure measured in centimeters (5, 10, 12, etc.). The letters “U” or “P” show how the edges are located, respectively, at an angle or parallel. There are channels marked with two letters at once, with “S”, “L”, “E” added to the main ones. This is an indication of the brand - special, light, economical.

Characteristics

The most popular standard sizes are 10P, 12P, 16P, 20P. The first of them is an equal-flange analogue, made from steel with excellent weldability by hot rolling without additional heat treatment. The weight of a 10P channel (1 linear meter according to GOST) is 8.59 kg. At the same time, the 10P analogue is characterized by a typical length (from 2 to 12 m).

Products marked 12P are produced similarly to those described above. Its weight is slightly larger and is estimated at 10.4 kg, which is 20% higher than 10P. This type of channel is produced in a standard length, and is used, like the analogue described above, if it is necessary to increase stability and rigidity, mainly in small architectural forms. However, 12P is preferable, if only because it allows you to save on metal consumption.

In the production of 16P and 20P, the hot rolling method is also used. The weight of the 16P channel is 14.2 kg, and that of the 20P is 18.4 kg with the same length. The 16P channel is used in the installation of temporary structures and the production of floors, and the 20P channel is used in heavily loaded analogues that can withstand static, dynamic, and cyclic loads.

Channel 20: application, size, weight

Channels 20, due to their design, the thickness of the walls and base, are used in the construction of massive high-rise buildings and industrial facilities. They are made from hot-rolled steel according to GOST 8240-97. The shelves are located on one side of the wall.

Unlike zeta profile structures, they are produced in standard sizes and weights, and deviations are allowed within 5%.

Considering that such channels can have different angles of inclination of the walls, before purchasing it is recommended to familiarize yourself with the technical characteristics and scope of application of metal structures.

What steels are channel 20 made of?

Based on GOST 8240-97, grade 20 channels are made of hot and cold rolled steel. The type of steel used in the production of the channel is indicated in the marking.

Hot-rolled channel is more durable; it is used in the construction of load-bearing walls in structures made of metal structures. They cope well with local vertical bending and are resistant to horizontal movements.

Cold-rolled channel 20 is more used for floors where detailed calculations of the load-bearing capacities of buildings are not carried out.

Dimensions and characteristics of grade 20 channels

Channel 20 (weight 1 meter 18.95 kg) is produced in two modifications:

1. Type U. It has a slope of internal edges, the angle is 4-10 degrees.
2. Type P. Channel with parallel walls.

Typical dimensions of U20 channels:

• 200 mm – wall width;
• standard shelf width up to 76 mm;
• the walls have a thickness of 5.2 mm, and the thickness of the shelf is up to 9 mm with a fluctuation of up to 0.5%;
• turning radius at the junction of the inner edge of the shelf and the walls – 9.5 mm;
• There will be about 54.43 m of channel in a ton of finished products.

P series channels

Many dimensions and parameters fully correspond to the U20 brand channel, only the radius of the outer curvature of the flange is up to 5.5 mm, the inner turn is up to 9 mm. The weight of the channel is slightly less, so there are more structures per ton of finished products.

The weight of the channel is calculated in accordance with the type of steel used at a density of 7850 kg/m3. This is a reference value. This parameter also depends on the composition, because the wall thickness can vary within 1%.

Privately supplied channel length parameters

At production facilities, all channels are produced in the form of a single strip, which is cut on machines to lengths ranging from 2-12 meters. The length depends on a number of conditions, some are set by manufacturers, others by metal warehouses:

• Measured length. It is 1.1-2.0 meters.
• A combination of measured and unmeasured lengths with the composition of an unmeasured batch in the delivery group up to 5%.
• Multiple measured length.
• Only unmeasured length - 1.1 meters.
• To individual order of the buyer.

The channel is packaged in batches of 4.5-8 tons, tied with steel tape in several places. At the ends of the batch, marking tags are installed, which indicate the channel brand, size and type. Transportation method: road and rail transport.

Scope of application

Channels of grade 20 are used in the construction of load-bearing metal structures of industrial and residential buildings, as well as for the construction of trusses and arched ceilings.

The products are suitable for the construction of pile-grillage foundations and as supports for small road bridges.

When purchasing products, it is recommended to make a minimum of welding connections; it is better to initially install ready-made monolithic structures without intermediate connecting seams. If necessary, welding is allowed in places where vertical supports and spacers are installed.

Channel 20 received the most positive reviews. Builders noted the fairly high strength, reliability and cost-effectiveness of this material, as well as ease of installation and excellent weldability, which speeds up and facilitates the construction process.

Channel 20

Channel 20 is a type of shaped steel that has a profile with a “P” section shape. There is a crossbar (wall) at the top of the product, and shelves on both sides. The workpiece works well in bending, withstanding axial loads, which improves the load-bearing loads of the metal structure itself.

Standard channel marking 20

The marking number 20 indicates that the distance between the edges of the shelves is equal to 20 cm. Depending on the angle of inclination of the shelves, the channels received different types of indices:

• 20 P, which indicates that the shelves of the product are located parallel to each other;
• 20 U - inclined internal edges of the shelves.

GOST standards 8240-97 describe the production of channels 20 by the method of hot rolling of metal on section rolling mills. In production, industrial companies use conventional steel grades st3ps and st3sp, which are characterized by excellent weldability. To produce more durable workpieces, the company uses 09G2S steel, which retains its characteristics even at different temperatures from −70°C to +425°C.

Channel 20 technical specifications

According to GOST 8240-97, the main characteristics of the production of this product include:

• Height - 200mm;
• Wall thickness - 5.2mm;
• The width of the product shelves is 76mm;
• Shelf thickness - 9mm;
• The actual weight of channel 20 is 8.4 kg/m;
• The radius of curvature of the shelves is 4 mm for a channel marked 20 U, and for 20 P this figure is 5.5 mm;
• R of the internal rounding of the workpiece is 9.5 mm.

Scope of application of channel 20

The high load-bearing capacity of channel 20 expands the scope of application of the product in almost all industries. As a rule, they are used in the construction of roof purlins or in the ceiling of multi-story buildings. If the certificate of channel 20 indicates the marking “B”, then such products have increased strength.

The low cost and high technical characteristics of the channel have found their application in various types of construction work, including the individual construction of cottages and summer houses, and the arrangement of personal plots. In industry and mechanical engineering they are used in the construction of work platforms, overpass columns, bridge structures, etc.

When choosing a manufacturing company for such products, pay attention to the guarantee for the production of channels 20, which must be in strict accordance with state requirements.
