cold rolled steel
Cold-rolled steel is steel produced by cold rolling. Cold rolling is a steel plate obtained by further rolling the No. 1 steel plate to a target thickness at room temperature. Compared with hot-rolled steel sheets, cold-rolled steel sheets have more accurate thickness, smooth and beautiful surface, and also have various superior mechanical properties, especially in terms of processing performance. Because cold-rolled raw coils are relatively brittle and hard, they are not suitable for processing, so usually cold-rolled steel sheets are required to be annealed, pickled and surface-leveled before being delivered to customers. The maximum thickness of cold rolling is below 0.1--8.0MM. For example, the thickness of cold-rolled steel sheets in most factories is below 4.5MM; the minimum thickness and width are determined according to the equipment capacity of each factory and market demand.
