Pre painted steel coil is a kind of product made by subjecting the strip steel that continuously degreasing the surface on the production line after chemical treatment such as phosphating, and then baking the strip steel coated with organic paint at high temperature. The surface of this steel sheet has a relatively bright color.

Features of Pre painted steel coil:
We suppliy steel grades of color coating products have high strength steel color, deep steel color coating, general molding used for color painting, and other advanced high-strength steel paints, such as double - phase steel or polyphase steel, which can improve the anti-wind ability.
Substrate Plate Type:
The base plate of steel color coated steel plate includes hot galvanizing, electro-galvanizing, aluminized zinc and other basic plates, as well as newly developed zinc-alumina magnesium base plate. The coating weight not only has the double thickness coating, but also has two different thickness coating.
Coated Layer Structure:
The coated products of steel are 2/2, 2/1, 1/1, 3/2, 2/1M, etc.
Coating Types:
steel color coating products include polyester (PE), fluorocarbon (PVDF) color coating, silicon modified polyester (SMP) color coating, high tolerance (HDP) and other paint varieties.
