Prime Quality Cold Rolled Sheet Coils , 0.15 ~ 4.0 mm, 500 ~ 2000mm , base plate for galvanized steel and color coated steel, etc
Introduction:
Cold-rolled coil is substrate of hot-rolled coil , produce under recrystallization temperature in condition of room temperature. Cold-rolled coil is not heated in the production process , so it don't exist the defect of pitting and iron oxide
which often exist in hot-rolled. It has good surface quality, highly polished.
On the one hand , it is the substrate of galvanized steel coil and color coated steel coil ,
On the other hand , it has precise size , uniform thickness, excellent surface quality ,
and offer good machinability , high strength , low yield limit and good stamping properties
