Process:



The annual capacity of Galvanized Line is 320,000 tons. We adopt the UEC hot dip galvanizing process which is the most advanced and wildly used in the world. The main specification of product is 0.15~1.5mm X 800~1250mm.

We could manufacture high performance GI with high zinc coating, non-spangle, minium spangle, regular spangle or big spangle along with the advanced processing of oiled and skin-passed. The product can be used in building materials and electrical appliance.
