Hot dip aluminum-zinc plate/coil
Galvanized zinc layer is made of aluminum alloy composed of aluminum and zinc, from55% aluminum, 43% zinc and 2% silicon in the solidification and high temperature 600 ℃, whose entire structure is made of aluminum - iron - silicone - zinc, forming dense of a quaternary alloy crystals.
Corrosion resistance:Itmainlydepends onthealuminumprotection. When the zinc being worn, the aluminum will form a dense layer of aluminumoxide,resistcorrosion material to prevent further corrosion inside.
Heat resistance:Aluminum zinc alloy steel sheet has excellent heat resistance, can withstand high temperaturesover 300centigrade, andis similar withaluminized steel high temperature oxidation resistance. Itoften used in chimney pipes, ovens, fluorescent lighting device and the device cover.
Heat reflective: Galvanized steel plate heat-reflective high rate is twice as galvanized steel, often used to makeinsulation
Economy: Because densityof55% AL-Znis smallerthan the density ofZn,so in the same weight and thickness of Galvanized zinc layer, aluminum-zinc steel plateislargerarea more than 3%of galvanized steel sheet.
Building: roof, wall, garage, wall insulation, pipe and modular housing
Automotive: muffler, exhaust, wipers, accessories, fuel tanks, truck boxes, etc.
Appliances: refrigerator back, gas stove, air conditioning, electronic microwave oven, LCDframe, CRTwith explosion-proof, LED backlight, electrical cabinets,
other: off heat insulation cover, heat exchangers, dryers,hot water etc.
The HDG is a kind of coated steel with the cold rolled steel, it is produced through applying zinc coat on both faces by hot dip process.So it has good performance in corrosion resistance. The company now has two lines of GI, the designed capacity total 300000 tons with the ...
