Along with the development of the era of science and technology now, channel steel manufacturers more and more, construction materials are constantly updated, you may have heard the building materials, steel channel and some people may not have heard, channel steel is built from and mechanical carbon structural steel, is a kind of complex profile steel steel, its cross section for the groove shape.Channel steel is mainly used in curtain wall engineering, building structure, mechanical equipment and vehicle manufacturing.
A channel is a strip of steel with a concave section.The specification is expressed in millimeters of waist height (h)* leg width (b)* waist thickness (d). For example, 120*53*5 means channel steel with waist height of 120 mm, leg width of 53 mm, channel steel with waist thickness of 5 mm, or 12# channel steel.For channel steel with the same waist height, if there are several different leg width and waist thickness, add a, b and c to the right side of the model to distinguish them, such as 25a# 25b# 25c#, etc.
Channel steel can be divided into ordinary channel steel and light channel steel.The specification of hot rolled ordinary channel steel is 5-40#.The specification of hot rolled flexible channel steel supplied by both parties is 6.5-30#.Channel steel is mainly used for building structures, vehicle manufacturing and other industrial structures, channel steel is often used with i-steel.
