Cold rolling is made of hot-rolled coils as raw materials, which are rolled at room temperature below the recrystallization temperature. The thickness of cold-rolled sheet is generally between 0.1--8.0mm. The thickness of cold-rolled sheet produced by most factories is below 4.5mm. The thickness and width of cold-rolled sheet are determined according to the equipment capacity and market demand of each factory.
