According to the manufacturing method,it is divided into two types:hot rolling and cold rolling,the thickness range is 0.3-4mm.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.
