1. Galvalume steel sheet(Aluzinc Steel Coil) description
Galvalume steel sheet 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 Zn
2. Application of Galvalume steel sheet(Aluzinc Steel coil):
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. Galvalume steel sheet(Aluzinc steel coil) features:
1) Galvalume steel coil is formable, weldable and paintable
2) Galvalume steel coil has superior long term corrosion resistance in the most atmospheric conditions
This is achieved through the combination of the sacrificial protection of zinc and the barrier protection
3) Galvalume steel coil coating out-perform galvanized coating from 2-6 times than galvanized steel
4. Galvalume steel sheet(Aluzinc Steel Coil) packing materials:
Each aluzinc steel coil 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
