1). cold rolled steel coil------ step 2). galvanized steel coil or galvalumed steel coil --------- step 3). prepainted steel coil -------- step 4). cuting steel coil into steel sheet---------- step 5). rolling steel sheet in to corrugated sheet. Packing &Shipping ApplicationCorrugated steel sheet profile widely used in roofing, wall decoration and interior decorative material.Characteristic
1. Outlook Beautiful and novel, rich colors, flexible combination, can be used in different building to express special original architectural styles in life.

5. Environmental material, can be used many times, will do no hard to the our environment.
6. Prime anti-fire application, which is confirmed by GB50222-95 as difficult to fire as B
7. Impact resistance, strength is 250-300 times of common glass, 2-20times of tempered glass,89. 8.Energy saving: Keep summer cool, winter warm. Heat insulation effect is higher 7%-25% than that of the common glass, then heat loss is greatly reduced.
9. Insulation resistance: Corrugated sheet with obvious effect of noisy.
10. Light in weight, and have very good beatification vision effect.
