Production Chart
Casting → Cold Rolling → Foil Rolling → Anneaning → solidification → prime coating → drying → cleaning → Degressing → Face coating → Sodification → winding inspection → Slitting → packaging → Inspection.
We have the technology of 3th layer coating (chemical conversion coating + 2 coating), with which we can meet the demands for multifunctional fin stock of our customers.
