What is aluminium-zinc plated sheet
Aluminium-zinc plated sheet is a steel plate plating on the basis of zinc with the addition of aluminium (passivation protection), the general composition of 55% aluminium, 43.5% zinc, 1.5% silicon, with excellent resistance to atmospheric corrosion, corrosion resistance of galvanized sheet 2-5 times, but also has the high temperature corrosion resistance of aluminium plate, smooth surface, good appearance, but the formation of its plating and resistance to welding a little worse. In foreign countries generally about 40% of aluminium zinc plating used directly, about 60% of the plate is further as a colour coated substrate.

Uses: building roofs, walls, electrical cabinets, home appliances, automobiles, colour coated substrates, etc.
- Aluzinc Color Coated Steel Coil
Description:
Aluzinc color coated steel coil is made by coating a steel substrate with an aluminium-zinc alloy, followed by an organic paint layer. The Aluzinc coating typically consists of 55% aluminium, 43.4% zinc, and 1.6% silicon.
Advantages:
1. Superior Corrosion Resistance: The aluminium content in the coating provides enhanced corrosion resistance, especially in harsh environments.
2. Heat Resistance: Better performance in high-temperature conditions due to the aluminium component.
3. Longer Service Life: The combined protective properties of aluminium and zinc result in a longer lifespan compared to regular galvanized steel.
4. Enhanced Reflectivity: The aluminium-zinc coating provides excellent reflectivity, making it suitable for roofing and siding applications where heat reflection is beneficial.
Disadvantages:
1. Higher Cost: Aluzinc coated steel is typically more expensive than galvanized steel, which may be a consideration for budget-sensitive projects.
2. Limited Color Variety: While it offers good aesthetics, the range of available colors and finishes may be more limited compared to galvanized color coated steel.
1. High Strength: SGC570 is a high-tensile steel with a minimum yield strength of 570 MPa. This makes it suitable for applications requiring high structural integrity.
2. Formability: Despite its high strength, SGC570 maintains good formability, allowing it to be shaped into various profiles without cracking.
3. Corrosion Resistance: The aluminum-zinc coating provides excellent protection against corrosion, significantly extending the material's lifespan.
4. Heat Reflectivity: The coating also offers high reflectivity of heat, which can contribute to thermal efficiency in buildings.
