We only produce cold rolled coils and coated steel coils, we buy raw materials from steel manufacturers - hot rolled steel coils
Step 1 - Cold Rolled Coil Production Process
We purchase hot-rolled coils of corresponding grades on demand, and produce cold-rolled coils after pickling, cold rolling, electrolytic cleaning, annealing, and skin pass processes.

Step 3 - Prepainted steel coil production process
Degrease the hot-dip galvanized coil through pretreatment, Apply primer, Curing, Cooling, Apply finish coat and other processes
