Channel steel is a long steel with groove-shaped cross-section, belonging to carbon structural steel for construction and machinery, and it is a section steel with complex cross-section, and its cross-section shape is groove-shaped.
channel steel is divided into ordinary channel steel and light channel steel. The specification of hot rolled ordinary channel steel is 5-40#. The specification of the hot rolled variable channel supplied by agreement between the supply and demand sides is 6.5-30#.
Channel steel according to the shape can be divided into 4 kinds: cold-formed equal edge channel steel, cold-formed unequal edge channel steel, cold-formed inner rolled edge channel steel, cold-formed outer rolled edge channel steel.

Common specification size table
Its specifications to waist height (h) * leg width (b) * waist thickness (d) of the number of millimeters, such as 100 * 48 * 5.3, said waist height of 100 mm, leg width of 48 mm, waist thickness of 5.3 mm channel steel, or 10 # channel steel. Waist height of the same channel steel, such as several different leg width and waist thickness also need to be added to the right of the model a b c to distinguish, such as 25 # a 25 # b 25 # c and so on.
Length of channel steel: small channel steel is generally 6 meters, 9 meters, 18 groove above 9 meters mostly. Large channel steel has 12 meters.
Scope of application:
Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed coil cabinets, etc. U Channel steel is also often used in conjunction with I-beams.
