Raw Material : the raw material steel plate or molten steel is poured into the coil loader, and the steel plate or molten steel is cut into a suitable size and rolled coil through mechanical equipment

Pickling: Put the master roll into the pickling tank, and remove impurities such as oxidation, rust and grease on the surface through the pickling liquid to make the surface of the steel plate smooth and clean

Cold rolling: The pickling master coil is cold rolled through a cold rolling machine, that is, the steel plate is rolled into a thinner cold rolled coil at room temperature

 Annealing: The cold-rolled coil is heated for a certain time and temperature to restore its original structure and mechanical properties

 Aluminum plating, zinc plating: cold rolled coil into aluminum zinc liquid or zinc liquid for zinc plating aluminum or zinc plating process to improve the corrosion resistance of steel coil
