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.
1. Superior corrosion resistance: The corrosion resistance of zinc-aluminum-plated steel sheet is 6-8 times higher than that of general galvanized sheet, which is usually guaranteed not to rust for 20 years.
2. High-temperature oxidation resistance: Aluminum-zinc-plated steel sheet will not undergo any discoloration or deformation even if it is used in a high-temperature environment of 315 degrees Celsius.
3. High heat reflectivity: The heat reflectivity of zinc-aluminum-plated steel sheet is higher than 75%, which is about twice as much as that of galvanized sheet, and it can achieve energy-saving effect by acting as a roofing and paneling in unpainted situation.
Uses: building roofs, walls, electrical cabinets, home appliances, automobiles, colour coated substrates, etc.
Coating content classification
55% alu-zinc steel plate: the coating consists of 55% aluminium, 43.4% zinc and 1.6% silicon, the corrosion resistance is 2-6 times of galvanised sheet, characterised by high-temperature corrosion resistance, smooth surface, good appearance, but the plating of the molding and weldability is slightly worse.
5% aluminium-zinc steel plate: plated with 5% aluminium, 0.1% mixed rare earth elements, the rest is zinc, corrosion resistance is galvanised sheet 2-3 times, characterized by the plating of the formation is very good, with good coating and welding performance, but the surface is not as bright as high alumina steel plate, fine, so rarely used bare.
