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.
