In use, it requires better welding, riveting performance and comprehensive mechanical properties. The raw material steel billet for channel steel is carbon or low alloy steel billets with a carbon content of not more than 0.25%. The finished channel steel is delivered by hot forming, normalizing or hot rolling. The specifications are expressed in millimeters of height (H) * leg width (b) * waist thickness (d), such as 100*48*5.3, which means waist height is 100 mm, leg width is 48 mm, waist thickness is 5.3 mm channel, or 10# channel steel. The same height of the channel, if there are several different leg width and waist thickness, also need to add a, B, C on the right side of the model to distinguish, such as 25#a, 25#b, 25#c and so on.
Channel steel is a long strip steel with a cross section, and belongs to the construction and mechanical carbon structural steel. It is a complex section steel, whose cross section has a groove shape. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing, etc..

At the same height, the light channel steel has narrower legs, thinner waist and lighter weight than ordinary channel steel. 18 - 40 is large channel steel, 5 - 16 channel steel is medium channel steel. Imported channel steel shall be marked with actual specifications, sizes and relevant standards. Steel import and export orders generally is identified in the corresponding (carbon steel or low-alloy steel), to use the required specifications. Except for specification, channel steel has no specific composition and performance series
Channel steel is divided into ordinary channel steel and light channel steel. Standard Specification for hot-rolled plain channel steel is 5-40#. Specifications for hot rolled flexible channel steel supplied by supply and demand agreement are 6.5-30#. Channel steel is mainly used for building structures, vehicle manufacturing, other industrial structures and fixed plates, cabinets, etc., and channel steel is often used in conjunction with i-beam.According to the channel shape and can be divided into 4 kinds: cold bending equilateral channels, cold-formed non equilateral channel steel, cold rolled edge channels, the cold bending edge channelsAccording to the theory of steel structure, it should be stressed by the channel plate, that is to say, the channel should stand rather than lie prone.
