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. Many are used in architectural and engineering structures. It is used for the manufacture of steel bars or for the manufacture of factory building frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc. It is also used for many mechanical parts that do not have high functional requirements. C, D grade steel can also be used for some professional steel applications.
