Cold rolled steel plate is the abbreviation for ordinary carbon structural steel cold rolled plate, also known as cold rolled plate. Cold rolled steel plates are hot-rolled steel strips of ordinary carbon structural steel, which are further cold rolled to produce steel plates with a thickness of less than 4mm. Due to the fact that rolling at room temperature does not produce oxide scale, the cold plate has good surface quality and high dimensional accuracy. In addition, annealing treatment results in better mechanical and technological properties than hot-rolled thin steel plates. In many fields, especially in the field of home appliance manufacturing, it has gradually been used to replace hot-rolled thin.

The hot-rolled steel plate products produced by have excellent properties such as high strength, good toughness, easy processing and good weldability, so they are widely used in manufacturing industries such as ships, automobiles, bridges, construction, machinery, and pressure vessels.
