ASTM A792 AZ60 AZ150 Galvalume 1220*1.1mm,1.25mm And More Sizes

Short Description:

Galvalume Steel Coil also named Aluzinc Steel Coil /Zinc-alum Steel Coil. The base material is non-alloy low carbon cold rolled steel coil. The surface composition is 55% aluminium, 43.4% and 1.6% silicon cured at 600℃.Galvalume has a gorgeous silver-white surface.

In terms of supply and demand, after years of adjustments and market competition, China’s galvalume steel coil industry has gradually stabilized. The market supply and demand relationship is relatively balanced. The production and sales rate is above 90% every year, and a considerable amount of products are exported every year.

Although the galvalume steel coil price is higher than that of ordinary hot-dip galvanized steel coil, but because the specific gravity of aluminum is smaller than zinc, the specific gravity of aluminum-zinc alloy coating 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.

Application
The galvalume steel coil is widely used on Construction, Steel Structure, Household Appliances, Transportation, Steel Structure, Roofing Sheet, Curtain Door.
