Unoiled Dry Chromated G350 Aluzinc Sheet/Al Zinc Coated Steel Coil

1. Al Zinc Coated Steel Coil description
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.
Galvanized layer is consisted of 55% aluminum and 43.3% of zinc and 1.6% of silicon per weight



2.Al Zinc Coated Steel Coil application(Aluzinc 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, etc




3. Al Zinc Coated Steel Coil (Aluzinc steel coil) features
1) Formable, weldable and paintable
2) Has 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. Al Zinc Coated 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
strapped by edge protection,and at least 4 steel straps through coil eye.Coil tube packedeye
to sky on wood pallet

 

Surface Treatment	Al Zinc Coated Steel Coil Feature
Chemical Treatment	minimize the chance of humid-storage staining forms a dark gray surface discoloration on the surface
	retain the bright metallic luster for a long period
Oil	minimize the tendency for humid-storage stain
Chemical Treatment and Oil	The chemical treatment provides very good protection against humid-storage staining, while the oil provides lubricity for operations.
Dry	must be transported and stored with special precautions to preserve low-humidity conditions.
Anti-finger print	minimize the chance of humid-storage staining forms a dark gray surface discoloration on the surface
