Channel steel is a long strip of steel with a U-shaped cross-section. According to its manufacturing process, it can be divided into stainless steel channel steel, galvanized channel steel, and carbon steel channel steel.
It is widely used in building structures, machinery manufacturing, vehicle production, and curtain wall engineering, among other fields.
