SS400 use

SS400 is often rolled into wire rod or round steel, square steel, flat steel, angle steel, I-beam, channel steel, window frame steel, etc., and medium and thick steel plates. It is widely used in construction and engineering structures. It is used to make steel bars or build factory building frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc. It is also widely used as mechanical parts that do not require high performance. C, D grade steel can also be used as some professional steel.
