Product Description

Brief Introduction

1. Prepainted Steel Coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized steel sheets. 
2. The base metals for Prepainted Steel Coil consist of cold rolled, HDG electro-galvanized and hot-DIP alu-zinc coated steel. The finish coats of Prepainted Steel Coil can be classified into groups as follows: Polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc. 
3. The production process has evolved from one-coating-and-one-baking to double-coating-and-double-baking, and even three-coating-and-three-baking.
