1. Cold Roll Steel Coil Introduction
1)Thickness 0.3mm-4.0mm
2)Width 600-1500mm
3)Standard SPCC, SPCD,SPCE,DC01, DC03,DC04
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 Coil
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.
