2 . Introduction of Base Metals of PPGI
The base metals for prepainted steel sheet consist of cold-rolled, HDG electro-galvanized and hot-dip alu-zinc coated steel sheet.
Cold-rolled base metal
The prepainted steel sheet processed with cold-rolled base metal features in its smooth and beautiful apperance and the machinability of cold rolled steel sheet, however, in case of any tiny scratch on the top coating may expose the cold rolled base metal in the air and the exposed base metal may rust soon. So the products of this kind can only be used as temprorary isolation measures and indoor materials with low requirements.
Hot-dip zinc coated base metal
The prepainted steel sheet with hot-dip zinc-coated base metal as its base metal not only has the protective function of zinc coating but also has an isolation and pretection function with its organic layer that prevents it from rusting and prolongs its service span longer, than that of hop-dip zinc steel sheet.
Hot-dip alu-zinc base metal
The hot-dip alu-zinc base metal adopts the hot-dip zinc-aluminum coated steel sheet(55% Al-Zn) as its prepainted base metal.
The corrosive resistance of the hot-dip alu-zinc coated steel sheet is twice to five times as much as that of the hot-dip zinc-coated base metal.
Neither serious oxygenation nor oxide scale might appear while continuously or intermittently working with an ambient temperature up to 490℃.
Electro-galvanized base metal
The prepainted electro-galvanized steel sheet adopts an electro-galvanized base metal coated and baked with an organic coating. Owing to the thin zinc-coated layer of the electro-galvanized base metal, the zinc content of the prepainted steel sheet of electro-galvanized base metal is usually 20/20g/㎡, and the products of this kind are not suitable for building walls or roofs outdoors. However, it has esthetic apperance and excellent machinability, which makes it suitable for electrical household appliances, acoustic devices, steel household appliances, interior decoration, etc
