Cold rolling is a process by which the sheet metal or strip stock is introduced between rollers and then compressed and squeezed.
It is a product obtained by cold-pressing a hot-rolled sheet. Due to the multi-pass cold rolling, the surface quality is better than that of the hot-rolled sheet, and after the heat treatment, good mechanical properties can be obtained.
