AZM150 Aluzinc Steel Roll Coil 55% Aluminum 43.5% Zinc 1.5% Si Galvalume Steel Regular Spangle ASTM A792M CS-B
Galvalume Steel Coil(55% Aluminium-Zinc Alloy Coated Steel Coil)
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.
Applications
Galvalume steel's superior protective characteristics and economical price make it ideal for :
- Residential and commercial exterior building materials
- Decking
- Cladding
- Cabinetmaking
Tipps
Storage: The product should be stored in a ventilated and dry place such as indoor, warehouse, etc. It should not be placed in an acidic environment for a long time. Outdoor storage should avoid rain to avoid condensation causing oxidation and discolouration.
Transportation: Avoid external impacts, the means of transport must support the steel coils, reduce stacking, and take effective measures against rain.
Processing: Use the same lubricant for cutting as for aluminium sheets. When drilling or cutting aluminium galvanised steel sheets, loose iron filings should be removed promptly.
Difference between GI and GL
The difference between galvanised steel and aluminium-zinc steel mainly lies in the different coating, the surface of galvanised sheet is evenly distributed with a layer of zinc material, the parent material plays the role of anodic protection, that is to say, the alternative corrosion of the zinc material protects the use of the parent material, and only when the zinc is all corroded to harm the parent material inside.
