Channel steel, also known as C-Channel or Parallel Flange Channel (PFC), is a type of profile, which belongs to carbon structural steel for construction and machinery, and is a section steel with complex sections. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.

Classification of channel steel

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 hot-rolled flexible channel steel supplied by agreement between the supplier and the buyer is 6.5-30#. Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed cabinets, etc. Channel steel is often used in conjunction with I-beam steel.

Channel steel can be divided into 4 types according to shape: cold-formed equilateral channel steel, cold-formed unequal-sided channel steel, cold-formed inner-curled channel steel, and cold-formed outer-curved channel steel.

According to the theory of steel structure, the channel steel wing plate should be stressed, that is to say, the channel steel should be standing, not lying down.
