Hot dipped galvanized steel sheet & coil is made of carbon steel coated in zinc utilizing the hot-dip process. The end result of this process is a layer of zinc on each side of the steel sheet or coil that is tightly adhered to the steel through the formation of an iron-zinc alloy bonding layer.

Color Coated Painted Steel Coil Corrosion Resistance EN10327 DX51D+AZ


Painted steel coil(PPGI PPGL) usually use roll paint technique to apply different color paint on the surface of galvanize steel or galvalume steel. Customers can choose colors referring to Ral color. Ral 3005, Ral 5012, Ral 6022, Ral 9006 is the most popular color.

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

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
