Galvalume is a new type of steel plate, which is formed by hot-dip plating of cold-rolled or hot-rolled steel. Its excellent corrosion resistance is gradually replacing galvanized sheets and is widely used all over the world. Aluminum-zinc plate usually has the following characteristics:

1. Very strong corrosion resistance: The corrosion resistance of aluminum-zinc plate is 6-8 times that of ordinary galvanized plate, and it can usually be guaranteed not to rust for 20 years.

2. High temperature oxidation resistance: The aluminum-zinc plate will not change color or deform after long-term use at 315 degrees Celsius.

3. High heat reflectivity: the heat reflectivity of galvanized steel is higher than 75%, which is about twice that of galvanized steel. It can be used as a roof and panel without painting, achieving energy-saving effects. Easy to process: it can meet punching, cutting, bending and other processing.

4. Beautiful appearance: the silver-white snowflake pattern is beautiful, and it can be used directly without painting.

5. Surface spraying: Aluminized zinc plate is a good base material for paint coating, and the composite coating of alloy and organic matter can provide more efficient protection and anti-corrosion.

6. More usable area: The specific gravity of the galvanized zinc plate coating (3.75 g/m3) is much smaller than that of the zinc coating (7.15 g/m3). Therefore, in the case of the same thickness of the steel substrate and coating, the use area per ton of aluminum-zinc plate is much larger than that of aluminum-zinc plate, which brings greater benefits to users. AZ150 is equivalent to: (1) 1,050 tons of 0.3mm thick galvanized sheet; (2) 1,035 tons of 0.5 mm thick galvanized sheet; (3) 1,025 tons of 0.7 mm thick galvanized sheet.

7. Wide range of applications: it can be used in building roofs, walls, garages, sound insulation walls, pipes and modular houses, silencers, exhaust pipes, wiper accessories, automobile fuel tanks and truck boxes, home appliances refrigerator back panels, Gas stove, air conditioner, electronic microwave oven, LCD frame, CRT explosion-proof belt, LED backlight, electrical cabinet, etc. As well as agricultural pig houses, chicken houses, granaries and warehouses.

The above are some knowledge points about galvanized steel, I hope to help everyone.
