Pre-painted steel sheets is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized steel sheets or galvalume steel sheets. The production process has evolved from one-coating and one-baking to double-coating and double-baking.                     

At present, we have built two large-scale double-coating-double baking production lines of prepainted steel sheet with a yearly output of 300000 tons, with a specification of 0.17--1.0mm thickness and 750-1250mm width.                                 

Prepainted steel sheets has better decorative effect than galvanized or galvalume sheets, and the color is novelty and beautiful.
