Cold rolling

Cold rolling is a steel sheet that is further rolled to a target thickness under room temperature conditions. Compared with hot-rolled steel sheet, the thickness of cold-rolled steel sheet is more accurate, and the surface is smooth and beautiful. At the same time, it has various superior mechanical properties, especially in terms of processing performance. Because the cold-rolled original coil is brittle and hard, it is not suitable for processing, so cold-rolled steel sheets usually require annealing, pickling and surface smoothing before they can be completed.
