Minimum Regular Spangle 0.47×1200 Galvalume Steel Coil 55% Aluminum Zinc Coated Steel Coil For Corrugated Metal Tile

Aluminium-zinc coils have good heat and oxidation resistance, no change of colour for a long time at 300°C, and can be used for a long time at about 500°C to 600°C. They have good resistance to water and soil corrosion. At the same time, it has excellent coating performance and processing performance, strong bonding to organic materials, and is a good substrate for coloured organic coated steel sheets.

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.
