1. Hot Dipped Aluzinc Steel Coil description
It is galvanized steel sheet with both zinc and aluminum, and is the ideal combination of anti-
corrosion and alkali-resistance of zinc,and the durability,heat-resistance,and acid-resistance
of aluminum. The galvanized layer is consisted of 55% of aluminum and 43.3% of zinc and
1.6% of silicon per weight
2. Hot Dipped Aluzinc Steel Coil application(galvalume Steel coil)
1) Construction: Roofing, cladding, structural sections, composite panels
2) Electric appliance: Washing machine, refrigerators, toaster, microwave
3) Miscellaneous: Air duct, lighting, computer casing
3. Hot Dipped Aluzinc Steel Coil (Aluzinc steel coil) features
1) Formable, weldable and paintable
2) Superior long term corrosion resistance in the most atmospheric conditions. This is achieved
through the combination of the sacrificial protection of the zinc and barrier protection of aluminum
3) Hot dip galvalume coating out-perform galvanized coating from 2-6 times than galvanized steel
4. Hot Dipped Aluzinc Steel Coil packing materials
Each hot dip galvalumetube wrapped by plastic film and waterproof paper, one steel strip strapping
on the galvalume steel coil circumference. 3 - 5 coils tube packed eye vertical on wood pallet, and
strongly strapped by edge protection, and at least 4 steel straps through coil eye. Coil tube packed
eye to sky on wood pallet

1. Coil description
It is a kind of coated steel coil/sheet. With the cold rolled steel of different strength and
thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot
dip process. In its coating,Al accounts for about 55%, Si 1.6%, while the remaining is zinc.
2. Main usage scope
1) Architecture roofs and outside walls of civilian,industrial buildings,garage doors,fencings
2) Appliances industry outer clad sheets for washing machine, refrigerator, television, air
conditioner and ventilation system,explosion-proof strip,solar water heater and appliance
3) Auto industry muffler,heat shields of exhaust pipe and catalytic converter, auto parts&
accessories under frame, signboard
4) Industrial instruments electric control cabinet, industrial refrigeration equipment
3. Coil packing
Each aluzinc steel coil tube wrapped by plastic film and waterproof paper, one steel strip
strapping on the coil circumference. 3 - 5 coils tube packed eye vertical on wood pallet,
and strongly strapped by edge protection, and at least 4 steel straps through coil eye. Coil
tube packed eye to sky on wood pallet
