0.75*1200 Aluzinc AZ120 AFP Galvalume Galvalume 55% ALU ZINC Steel Coils For Corrugated Metal Roof Tile

Aluminium-zinc steel is composed of an aluminium-zinc alloy structure, consisting of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600 degrees Celsius. Its entire structure consists of aluminium - iron - silicon - zinc, the formation of dense tetrameric crystals of an alloy coated steel.

Main advantages

1, smooth surface, excellent resistance to atmospheric corrosion, its corrosion resistance life is 2-6 times higher than hot-dip galvanised steel;

2, with good heat and oxidation resistance, it does not change colour for a long time under 300℃, and it can be used for a long time around 500℃. In addition, the heat reflectivity of the product is higher than 75%, which is 2 times higher than that of galvanised sheet;

3, has excellent paintability and good processing performance. The combination of machine material is strong, which is the best choice for colour coated steel sheet substrate. Its processability and weldability are similar to that of hot galvanised sheet, and it can be processed by cold bending and stamping, and has a good appearance.
