Galvalume coil has excellent corrosion resistance. Aluminized zinc layer physical isolation, electro-chemical protection, and trivalent aluminum ion doping effect of the Galvalume coil has a good corrosion resistance. The life of galvalume coil is 2 to 6 times that of ordinary galvanized steel In the same environment.

Galvalume coil has good thermal reflectivity. Its reflection coefficient is twice as the hot galvanized sheet, in the summer can reduce the indoor temperature, reduce air conditioning electricity consumption.

Galvalume coil for construction industry:
Main applications are roof panels, within the board, keel, (purlins), pipes.
Common grades: DC51D + Az, S350GD + Az, S550GD + Az.

Affected by cost and environmental (spray) requirements factors, Galvalume coil with a beautiful appearance and excellent corrosion resistance, more and more alternative for hot-dip galvanizing and cold-rolled coating steel. Galvalume coil in the processing of the need to deal with the edge of the zinc aluminum has 180 plated 0T bending without zinc cracking requirements; Since the CNC machining of claim wave plate edge wave; As the appearance of the galvalume coil pieces, requiring the surface of zinc spangle, bright and no obvious visible defects.

Appliance industry requirements for galvalume coil products.

Main use: refrigerator backplane, air conditioning washing machine base, explosion-proof belt Water heater tube, monitor, TV backplane, satellite antenna pot and so on
