Specifications

Color coated steel coil
1.High quality
2.Quick delivery
3.Certification: ISO9001
 

I Brief Introduction

Color coated steel coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized steel sheets.

1. The base metals:Cold rolled, HDG electro-galvanized and hot-dip alu-zinc coated steel. The finish coats can be classified       

into groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.

2. Production process: One-coating-and-one-baking, double-coating-and-double-baking, three-coating-and-three-baking.

3. Color: Oange, cream-colored, dark sky blue, sea blue, bright red, brick red, ivory white, porcelain blue, etc.
