1. Aluzinc steel coils simple description
Aluzinc steel coils are kinds 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 Zn. Aluzinc steel coils enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn.
2. Aluzinc steel coils main application
1) Construction: Roofing, cladding, structural sections, composite panels, etc.
2) Electric appliance: Washing machine, refrigerators, toaster, microwave, etc.
3) Miscellaneous: Air duct, lighting, computer casing, etc.
3. Aluzinc steel coils features:
1) Aluzinc steel coils are formable, weldable and paintable.
2) Aluzinc steel coils have superior long term corrosion resistance in the most atmospheric conditions. This is achieved through the combination of the sacrificial protection of the zinc and the barrier protection of the aluminum.
3) Aluzinc steel coils coating out-perform galvanized coating from 2-6 times than hot dip galvanized steel.
4. Aluzinc steel coils packing materials:
Each aluzinc steel coils tube 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
