Dx52D Cold Rolled Galvalume Gi Coil

Product Description

1.Galvalume Steel Coil, also known as Aluminum zinc alloy Steel Coil, or alu zinc steel coil, has better mechanical advantages than traditional material.

2.Galvalume steel contains 55% aluminum, 43.5% zinc, 1.5% silicon and other microscale component.

3.Galvalume steel coil possesses extreme anti-corrosion property. It adopts aluminum as the oxidation film, and also the zinc-iron electrochemistry principle , which makes the anti-corrosion property 2~5 times better than galvanized steel at the same coating level.

4.Galvalume steel coil possesses the amazing appearance known as diamond grain. This nice appearance can be applied on building interior decoration, and exterior decoration panel.

 ProductionProcess

The core procedure of galvaluming process is putting the carbon steel sheet into the molten aluminum zinc pot, about 450 Celsius degree, then an alu zinc layer film adhere to the base carbon steel sheet.
