1. Description
 
Prepainted Galvanized 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 in to groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.
The color of the prepainted steel sheets has a very wide selection, like orange, grey, blue, red,yellow,ivry, white, etc.
Introduction about Hot-dip zinc coated base metal: The prepainted steel sheet with hot-dip zinc coated base meatl as its base metal not only has the protective function of zinc coating but also has an isolation and protection function with its organic layer that prevents it from rusting and prolongs its service span longer, than that of hot-dip zinc steel sheet.
 
2. Coating Structure
 
Type of Coating Structure
2/1: Coat the top surface of the steel sheet twice, coat the lower surface once, and bake the sheet twice.
2/1M: Coat and bake twice for both top surface and undersurface.
2/2: Coat the top/lower surface twice and bake twice.
 
Usage of Different Coating Structures
2/1: The anti-corrosion property and sxratch resistence of the single-layer backside coating is poor, however, its adhesive property is good. The prepainted steel sheet of this kind is mainly used for sandwich panel;
2/1M: Back coating has good corrosion resistence, scratch resistence and molding performance. Besides it has good adhesion and is spplicable for single layer panel and sandwich sheet.
2/2: The anti-corrision property, scratch resistence and processing property of the backside coating of prepainted steel sheet is better, so it is widely used for roll forming. But its adhesive property is poor, so it is not used for sandwich panel.
