Cold rolling is a steel sheet which is further rolled to a target thickness at room temperature under a recrystallization temperature. Compared with hot-rolled steel sheets, cold-rolled steel sheets are more precise in thickness and have a smooth and beautiful surface.

The cold-rolled sheet has good performance, that is, cold-rolled, cold-rolled strip and steel sheet with thinner thickness and higher precision can be obtained, with high straightness, high surface finish, clean and bright surface of cold-rolled sheet, and easy coating. The processing, variety, wide use, and high stamping performance and non-aging, low yield point, so cold rolled sheet has a wide range of uses, mainly used in automotive, printed iron drums, construction, building materials, bicycles and other industries, It is also the best choice for the production of organic coated steel sheets.
