1. Introduction
It is galvalume steel coil, steel sheet with surface coated with zinc aluminum alloy. It is an ideal combination of zinc's anti-corrosion, alkali resistance and aluminum's durability, heat resistance and acid resistance. The coating consists of 55% aluminum and 43.3% zinc and 1.6% silicon.
2. Application
1) Construction: roof, cladding, structural profiles, composite panels
2) Electrical appliances: washing machine, refrigerator, toaster, microwave oven
3) Others: air duct, lighting, computer case
3. Features
1) Formable, weldable and paintable
2) Excellent long-term corrosion resistance under most atmospheric conditions. This is
Realized by combining the sacrificial protection of zinc and the barrier protection of aluminum
3) In case of same weight per square meter of coating, corrosion resistance of hot dipped galvalume is 2-6 times better than galvanized steel.
4. Packaging details
Each galvalume steel coil is bound with plastic film, waterproof paper, and several steel belts. It is standard export package, suitable for shipment on sea.
5. Shipment
Each galvalume steel coil is about 3 - 5 tons, it is suitable to ship them with container. In general, one 20 feet container loads maximum weight 27 tons. At the same time, bull shipment is also ok when container shipment cost is high.
