High Quality and Low Price Customized Processing Steel U Channel for Building Use Channel Steel

Channel steel is a carbon structural steel for construction and machinery. It is a steel with a complex cross section and a groove shape. Channel steel is mainly used in building structures, curtain wall engineering, mechanical equipment and vehicle manufacturing. It is required to have good welding, riveting and comprehensive mechanical properties during use. The raw material billet for producing channel steel is carbon steel or low alloy steel billet with a carbon content not exceeding 0.25%. The finished channel steel is delivered in the state of hot forming, normalizing or hot rolling. Its specifications are expressed in millimeters of waist height (h)*leg width (b)*waist thickness (d), such as 100*48*5.3, ​​which means a channel steel with a waist height of 100 mm, a leg width of 48 mm, and a waist thickness of 5.3 mm, or 10# channel steel. If there are several different leg widths and waist thicknesses for channel steels with the same waist height, a b c should be added to the right of the model to distinguish them, such as 25#a 25#b 25#c, etc.
