High Quality 20/7um 0.45mm Prepainted Galvanized PPGI Steel Coil

High Quality 20/7um 0.45mm Prepainted Galvanized PPGI Steel Coil substrate properties

Electroplating zinc substrate: the coating is thin, corrosion resistance is not as good as hot dip galvanized substrate;

Hot dip galvanized substrate: the thin steel plate is immersed in the molten zinc groove, so that its surface adheres to a layer of zinc, this galvanized sheet has good coating density and weldability. 

Hot aluminized zinc substrate: 

High Quality 20/7um 0.45mm Prepainted Galvanized PPGI Steel Coil is coated with 55% Al-Zn and has excellent corrosion resistance. High Quality 20/7um 0.45mm Prepainted Galvanized PPGI Steel Coil service life is more than four times that of ordinary galvanized steel plate. High Quality 20/7um 0.45mm Prepainted Galvanized PPGI Steel Coil is the replacement product of galvanized sheet.
