The channel is what? Types, description and scope of the channels

The channel is a product very demanded today, made of metal. Its main distinguishing feature is the section of the U-shaped form. The thickness of the finished product can be from 0,4 to 1,5 cm, and the height of the walls - 5-40 cm Thin-stranded products are manufactured by processing the flexible strip with the help of special profile mills. Channel bars produced from non-ferrous metals are obtained after processing the billet by pressing and extrusion, and steel bars by the technology of hot rolling of metal billets on long-length mills. All varieties of this material are widely used in the construction industry.

Manufacturing of steel channel bars

The steel channel (GOST 8240-97) has a pronounced difference from the conventional beam, which consists in the presence of a special section of the U-shape. Such metal products are produced by rolling blanks by a hot method or using cold-deformation technology of steel sheets. It is produced in the form of steel long products 3pc / cn5 and rolled from the alloys 09g2s. Channel bars, depending on the form, are divided into two varieties:

• Parallel - the internal faces are located strictly parallel to each other;
• Inclined - internal faces are placed under a slope.

Scope of application

As mentioned above, the channel is a very popular and popular material, without which no construction can do. It is used for the erection of buildings and structures for residential and industrial purposes, private and country houses, fences and fences, bridges, metal structures and farms.

Hot rolled channel

One of the varieties of steel is the hot-rolled channel, the section of which is also U-shaped. It is made in the form of two shelves, which are parallel to each other, and one connecting wall. Such a channel is divided into 3 varieties:

• With multiple non-dimensional length;
• With a multiple dimensional length;
• With a measured length.

As for the size of the channel, they can be non-standard, because everything depends on the wishes and requirements of the customer. Internal faces should have a slope of not more than 10%. The hot rolled channel is a universal material for light and heavy industries.

Varieties

Today there are other varieties of hot-rolled channel bars, for example, special for car building and the same for the automotive industry.

The bent steel channel channel is made of low-alloyed, hot-rolled, cold-rolled and carbon steel on bending machines. It is divided into two types: unequal and equilateral. It is used such metal rolling in cases when the construction to be constructed will have a huge load on the bend. To produce a low-alloy steel channel, low-alloy steel is used (as the name suggests). It is characterized by high resistance to various dynamic loads and large fluctuations in air temperature.

Channel: dimensions

The table below contains the characteristics of the Y-channel channels (faces are inclined).

The following table contains the characteristics of hot-rolled U-channels with parallel faces.

Legend:

• T is the thickness of the shelf;
• B is its width;
• H - height of the finished product;
• S is the wall thickness.

Thus, the steel channel is a product designed to give the constructed structures a higher stability. The axial load is taken up by the metal rolling and spreads evenly on its surface. Due to this, high rigidity and durability of metal structures are provided under bending loads.
