Brief IntroductionSpecifications of Cold Rolled black annealed Steel Coil/Sheet:

Production Lines: Three Lines in all. with an output of 50,000MT Annually.

Applications for cold rolled Steel coil: 

1) For the further producing of hot dip galvanized steel products

2) Cold rolled Steel Coil: Auto manufacture, Oil drum, Transformer's tank panel, Furniture etc.

Process of Cold Rolled Steel Tape:

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’s usage with minimum harm to natural environment.
