Channel is the section for the steel strip shape groove. Steel section shape groove shaped.
Channel is the section groove strip steel. Channel steel is used in the construction and machinery for carbon structural steel, steel steel section is complex, its sectional shape groove. Channel steel is mainly used for building structure, the curtain wall engineering, mechanical equipment and vehicle manufacturing etc.. Request it has better welding, riveting performance and comprehensive mechanical properties in use. Steel billet production raw materials are carbon content not exceeding 0.25% of the carbon steel or low alloy steel billet. Product channel steel after hot forming, normalizing or hot-rolled state of delivery. The specifications to waist high (H) * leg width (b) * waist thick (d) millimeter number representation, such as 100*48*5.3, said waist height 100 mm, width of 48 mm steel legs, waist thickness was 5.3 mm, or 10# channel. Waist high the same channel, such as a wide legs and waist several different thickness also need to add a B C to be the difference in the types of the right, such as 25#a 25#b 25#c etc..
