1. Brief introduction It is galvanized steel sheet with 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) Electric appliance: Washing machine, refrigerators, toaster, microwave
3) Miscellaneous: Air duct, lighting, computer casing
4. 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
5. Packing details 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
