Product Description:
The hot-dip galvalume/ aluzinc steel coil is a kind of coated steel with the cold rolled steel as substrate, produced through applying Al-Zn coat on both faces by hot dip process.
In its coating, Al accounts for about 55%, Si 1.6%, Zn 43.4%. It enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative.

Product Characteristics:
Machinability: It can satisfy the processing requirements of rolling, coiling and others processes alike.
● Thermal resistance: Common GI steel plate normally works under 230°C, and has its color changed at 250°C, however, Galvalume steel plate can sustain the enviornment at 315°C for long time.
● High reflectivity: Reflection ability of heat and light is twice as much as those of hot-dip galvanized steel sheet, and its reflectivity is more than 0.70, exceeding 0.65 (required by the EPA Energy Star Standard), which is an ideal construction materials of saving energy.
● High Corrosion Resistance: Galvalume steel sheet has better performance in corrosion resistance than GI sheet of the same thickness and its service life is 2-6 times longer than general GI sheet
