Aluzinc Coated Galvalume Zincalume Steel Coil

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.

Performance and major applications:
Excellent weather resistance allows for over 20 years of service without maintenance.Early test results of theroof and wall system indicate that it has survived in decades of intense sun exposure,exposure to the sun,erosion from industrial waste,and temperature and pressure without requiring any malntenance.There are morethan 500 million square meters of construction in the world.Aluminium-zinc plate is the choice of architects andhomeowners of all ages,and its excellent resistance to erosion is the reason why this type of roof and wall surfaces widely used.Studies have shown that such roofing systems can be expected to last 30 years or more in mostcases and do not require their own maintenance and repair.

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.
