1. Introduction of base metal
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℃.
