Cold-Rolling Production Line

The raw material for making cold rolled plate is hot-rolled steel roll after pickling iron oxide. Cold-roll plate is make in a progress through cold rolling mill with multi-step rolling to deformation, after a series electro-cleaning, annealing and finishing work, created a cold-roll plate.

Galvaluming Production Line

The cold-rolled steel strip send to continuous hot-dip Galvaluming line to electrolytic cleaning, and then send to be annealed in the continuous annealing furnace. After annealed, dip the plate in the molten Al-zinc pot for hot-dip galvanization. The product is finally formed after finishing, straightening, and passivation process.

Hot-Galvanizing Production Line 

The cold-rolled steel strip send to continuous hot-dip galvanizing line to electrolytic cleaning, and then send to be annealed in the continuous annealing furnace. After annealed, dip the plate in the molten zinc pot for hot-dip galvanization. The product is finally formed after finishing, straightening, and passivation process.  

Pre-Painted Production Line

Is the products coated steel sheet (galvanized, zincalumed, cold plate, etc.) after surface chemical treatment (degreasing, phosphating, and chromium hydrochloric acid passivation) and coated (roller) with coatings, again baking to forming.
