after cold-rolled steel sheet is cold-rolled steel plate production. is cold-rolled at room temperature to further rolling of thin steel plate to the thickness of the plate as the goal. and comparison of hot-rolled steel, cold-rolled steel sheet thickness more precise, and smooth surface, beautiful, but also with a variety of superior mechanical properties, especially the processing performance. comparison of the original volume because the cold hard brittle, not suitable for processing, so usually require cold-rolled steel sheet after annealing, pickling, and surface roughness to the customer after. is the maximum thickness of cold-rolled 0.1 - 8.0mm following, such as most of the factory is the thickness of cold-rolled steel sheet 4.
5mm following; at least thickness, width is based on the equipment of the plant capacity and market demand to decide.
