Features of Cold Rolled Coil: 1) cold rolled steel coil is manufactured to have a long durability, strong corrosion resistance and shiny surface. 2) cold rolled steel coil features excellent forming properties, paintability, weldability, and is suitable for fabrication by forming, pressing and bending.
Package of Cold Rolled Coil: Strapped with min three strapping strips, covered by anti-water paper and plastic film, fixed on the iron or wooden pallets by strapping strips and covered by plastic bag to prevent damage from transportation.
Process of Cold Rolled 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.
Also we can make round or sharp edge with additional process and special machines.
Heat treatment: Advanced annealing, tempering and hardening techniques will help to produce proper mechanical property of the products to insure our client& acute;s usage with minimum harm to natural environment.
