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. 

Product features: 

(1) High Quality 20/7um 0.45mm Prepainted Galvanized PPGI Steel Coil has good durability, corrosion resistance compared with galvanized steel longer life; 

(2) High Quality 20/7um 0.45mm Prepainted Galvanized PPGI Steel Coil has good heat resistance, compared with galvanized steel plate at high temperature is not easy to discolor; 

(3) High Quality 20/7um 0.45mm Prepainted Galvanized PPGI Steel Coil has good thermal reflectivity; 

(4) High Quality 20/7um 0.45mm Prepainted Galvanized PPGI Steel Coil has similar processing performance and spraying performance as galvanized steel plate; 

(5) High Quality 20/7um 0.45mm Prepainted Galvanized PPGI Steel Coil has good welding performance. 

(6) High Quality 20/7um 0.45mm Prepainted Galvanized PPGI Steel Coil has good performance-price ratio, durable performance and competitive price. As a result, architects, engineers, and manufacturers have been widely used in industrial buildings, steel structures, and civil facilities such as garage doors, eaves, and roofs folding
