According to the manufacturing method, it is divided into two types: hot rolling and cold rolling,the thickness range is 0.3-4 mm.
Cold rolling is a steel coil obtained by further thinning the No. 1 steel sheet to a target thickness under room temperature conditions. Compared with hot-rolled steel, cold-rolled steel has a more precise thickness, smooth and beautiful surface, and also has various superior mechanical properties, especially in terms of processability. Because cold-rolled raw coils are relatively brittle and hard, and are not suitable for processing, cold-rolled steel sheets are usually required to be annealed, pickled and surface smoothed before being delivered to customers.
