The channel steel is a long strip of steel with a section of groove shape. It is a carbon steel for construction and machinery. It is a section steel with a complex section and its cross-sectional shape is groove-shaped. Due to the different specifications of the channel steel, it is mainly used for building structures, curtain wall engineering, mechanical equipment and vehicle manufacturing.
It is required to have good welding, riveting performance and comprehensive mechanical properties in use. The raw material billet of the channel steel is a carbon steel or a low alloy steel billet having a carbon content of not more than 0.25%. The finished channel steel is delivered by hot forming, normalizing or hot rolling. The channel specifications are expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d), such as 100 * 48 * 5.3, indicating a waist height of 100 mm, a leg width of 48 mm, and a waist thickness of 5.3 mm. Channel steel, or 10# channel steel. If the waist height is the same, if there are several different leg widths and waist thicknesses, you need to add a b c to the right of the model, such as 25#a 25#b 25#c, etc.
Channel structures are often used in conjunction with I-beams in building structures, vehicle manufacturing, other industrial structures and fixed cabinets.
According to the shape of the channel steel, it can be divided into four types: cold-bending equilateral channel steel, cold-bending unequal-edge channel steel, cold-bending inner-buckling channel steel, and cold-bending outer-rolling channel steel.
