Galvalume Steel Coil
The galvalume & aluzinc steel sheet in coil uses the cold-rolled steel sheet as a substrate and solidified by 55% aluminum, 43% zinc and 2% silicon at 600 °C. It combines the physical protection and high durability of aluminum and the electrochemical protection of zinc. It is also called aluzinc steel coil.
Advantage:
Strong corrosion resistance, 3 times that of galvanized steel sheet.
The density of 55% aluminum is smaller than the density of zinc. When the weight is the same and the thickness of the plating layer is the same, the area of the galvalume steel sheet is 3% or larger than that of the galvanized steel sheet.
The coating consists of 55% aluminum, 43.5% zinc, and 1.5% silicon in weight ratio, respectively. The production process of aluminum zinc steel sheet is similar to that of galvanized steel plate and aluminum plated plate, and it is a continuous melting coating process. 55% aluminum zinc alloy coated aluminum zinc steel plate has superior corrosion resistance compared to galvanized steel plate of the same thickness when exposed to the same environment on both sides. 55% aluminum zinc alloy coated aluminum zinc steel ( 55% Alu-zinc Steel) plate not only has good corrosion resistance, but also color coated products have excellent adhesion and flexibility.
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.
