Cold rolled steel is produced by cold rolling. Cold rolling is a steel plate that further thins the No.1 steel plate to a target thickness at room temperature. Compared with hot-rolled steel sheet, cold-rolled steel sheet is more precise in thickness, smooth and beautiful in surface, and has a variety of superior mechanical properties, especially in processing performance. It is mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commerce. The construction industry uses it for anti-corrosion building panels and roof grilles, while the automotive industry manufactures corrosion-resistant parts.
