BIN zinc 40-275 prepainted galvanized steel coil with 0.3mm
The base metals for prepainted steel sheet consist of cold rolled, HDG electro
-galvanized and hot-dip alu-zinc coated. The finish coats of prepainted steel sheets can be classified into groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride,
high-durability polyester, etc.
The production process has evolved from one-coating-andone-baking to double-coating-and-double-baking, and even three-coating-and-three-baking.
The color of the prepainted steel sheet has a very wide selection, like orange, cream-colored, dark sky blue, sea blue, bright red, brick red, ivory white,
porcelain blue, etc.
The prepainted steel sheets can also be classified into groups by their surface textures, namely regular prepainted sheets, embossed sheets and printed sheets.
