Cold-Rolled

Steel PlateCold-rolled steel plates are steel plates produced by cold rolling. Cold rolling means further rolling steel plates into those with target thickness. Compared with hot-rolled steel plates, cold-rolled steel plates have more accurate thickness, smooth and beautiful surfaces, as well as various excellent mechanical properties, particularly machinability. The cold-rolled original coils are relatively brittle and hard and hardly applicable for machining, so the cold-rolled steel plates should be generally delivered to customers after annealing, acid pickling and surfacing. The largest cold rolling thickness is 0.1-8.0MM, for example, the thickness of cold-rolled steel plates in most factories is less than 4.5MM; the smallest thickness and width are determined according to the equipment capacity of all factories and market demands.
