1.Prepainted steel sheet is coated with organic layer,which provides higher anti-corrosion property and a longer life span than that of galvanized steel sheets.
2.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 polyester,high-durability polyester,polyvinylidene fluoride etc.
3.The production process has evolved from one-coating & one-baking to double-coating & double-baking.
4.The color of the prepainted steel sheets 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 prepainted steel sheets can also be classified into groups by their surface texture,namely regular prepainted sheets,embossed sheets and printed sheets.
6.The prepainted steel sheets are mainly provided for various commercial purposes covering architectural construction,electrical household appliances,tranportation etc.
