914-1250mm Building Material Galvalumealuzinc Steel Coil Roofing Steel
Galvalume Steel Coil
The production process of HDG Continuous galvalume Line produces Hot-Dipped Galvalum steel sheets from base metal of Cold Rolled Coil, process consist of cleaning or degreasing, pickling to remove scale and residual from the surface, annealing furnace is used to achieve desired mechanical properties for strip, then galvalume by coating steel with a layer of zinc by immersing the metal in a bath of molten alu-zinc, the steel sheet alloys with the zinc and aluminum to bond coating onto the strip surface. After hop-dipped galvlume process, variety of surface treatment can be applied, chemical passivation, chromate, oiling etc. Galvalume steel sheets are widely used in automobiles, home appliances, IT, high-grade building materials and ships and other fields.
Aluminum zinc alloy coated steel plate has smooth surface and excellent atmospheric corrosion resistance. Its atmospheric corrosion resistance is 2 ~ 6 times higher than that of hot-dip galvanized steel plate with the same coating thickness; At the same time, it has high-temperature corrosion resistance similar to hot-dip aluminum plate. Aluminum zinc alloy coated steel plate has the characteristics of hot-dip galvanized steel plate and hot-dip aluminum plate. Therefore, aluminum zinc alloy coated steel plate can be used wherever hot-dip galvanized steel plate is used, and can also partially replace hot-dip aluminum plate. It has a wide range of applications, such as roof panel, wall panel, light steel keel Heating fins, automobile body, oil tank, armored steel strip of cable, skeleton material of plastic shed, granary, shipping container, household appliances and appliances, oven, explosion-proof steel strip, outer covering parts of air conditioning and ventilation system, solar water heater, packaging box of chemical products, color plate base plate, welded pipe, steel window, raw materials of cold-formed steel in metallurgical industry, etc, The application prospect is very broad.
