The price of galvalume steel coil is higher than that of ordinary hot-dip galvanized steel sheet, but because the specific gravity of aluminum is smaller than zinc, the specific gravity of galvalume coils is only 3.75kg/dm3, while the specific gravity of zinc is 7.1kg/dm3, so the coating weight The thickness of the aluminum-zinc alloy coating of 150g/m2 (double-sided) is the same as that of the hot-dip galvanized steel plate with the coating weight of 275g/m2 (double-sided), which greatly saves the more expensive coating metal.

Product Advantages
1.Available for customized specification on customers’ request.
2.Perfect Corrosion Resistance. The service life of galvalume is 3-6times as long as that of galvanized surface.
3.Perfect Processing Performance. Fully meet the requirement of roll processing, stamping, bending, ect.
4.Perfect Light Refelectivity. The ability of reflecting light and heat is twice that of galvanizing.
5.Perfect Heat Resistance. Galvalume products can be used at 315 degree Celsius for a long time without discoloration.
6.Excellent adhesion between the paint. Easy to paint and can be painted without pretreatment and weathering.
