1. Cold Roll Steel sheet Introduction
1)Thickness: 0.3mm-4.0mm
2)Width: 600-1500mm
3)Standard: SPCC, SPCD, SPCE, DC01,DC02,DC03, St12,St13,St14
4)Surface treatment: dry, oiled or coated.
5)Packaging:
Strapped with min three strapping strips, covered by antiwater paper and plastic film, fixed on the iron or wooden pallets by
strapping strips and covered by plastic bag to prevent damage from transportation.
6)Application:
Construction plate,boiler plate,container plate,shipbuilding plate,steel pipe making.
all kinds of industries and manufacturing structural applications.
2. Process of Cold Roll Steel Sheet
Pickling: To clean the dust and rust points on the surface.
Cold Rolling: Digital rolling control system produces minimum thickness tolerance,
helps to prevent twist and improve straightness.
Slitting: Precise slitting machinery helps control the best width tolerance and avoid
camber or cracker.
