Features of cold-rolled steel coil :

1, cold rolled steel coil thickness more accurate, smooth surface, beautiful, but also has superior mechanical properties, especially machining performance.

2. The maximum thickness of cold-rolled steel coil is less than 0.1-- 8.0mm, such as the thickness of cold-rolled steel coil in most factories is less than 4.5mm;The minimum thickness and width are determined according to the equipment capacity and market demand of each plant.

3, cold rolled steel mill power, low rolling efficiency, and the rolling process in order to eliminate the work hardening have to carry out intermediate annealing, so the cost is higher, but cold rolled steel surface bright, good quality, can be used to process finished products, cold rolled steel is widely used.
