30mm-1500mm Galvalume steel coil Roofing Sheet AFP

Galvalume steel coil introduction:

Hot-dip aluzinc steel sheet is substrated on cold rolled steel(CRC)in various strength and specification Coating composition is 55％aIuminum in weight ratio．43 4％zinc．and 1 5％silicon with excellent corrosion and heat resistance performance.

The surface of galvalume steel coil features a unique star-shape, smooth and plain, with silver color as primary colour. Its special plating structure could be well corrosive -proof.

Its lifespan normally could reach 25 years. It is as well in heat-resistant as used in 315℃ high temperature; The plating and paint film with good adhesion would be excellent in processability including punching press, shearing, and welding, etc., and also it performs well in electro-conductivity.

The advantage of galvalume steel coil :

1. Strong corrosion resistance, 3 times that of galvanized steel coil .
2. The density of 55% aluminum is smaller than the density of zinc. When the weight is the same and the thickness of the plating layer is the same, the area of the galvalume steel sheet is 3% or larger than that of the galvanized steel sheet.
