1. Color steel 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 Color steel consist of cold rolled, HDG electro-galvanized and hot-dip alu-zinc coated steel. The finish coats of Color steels 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.
4. The color of the Color steel has a very wide selection, like orange, cream-colored, dark sky blue, sea blue, bright red, brick red, ivory white, porcelain blue, etc.
5. The Color steels can also be classified into groups by their surface textures, namely regular prepainted sheets, embossed sheets and printed sheets.
