The Functional Characteristics Of Galvalume Sheet

With the development of industry, Galvalume Sheet has been used in many occasions due to its excellent functionality. Galvalume Sheet consists of an aluminum-zinc alloy structure formed by solidification of 55% aluminum, 43.4% zinc and 1.6% silicon at a high temperature of 600. The whole structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary crystal alloy.

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. Galvalume Sheet usually has the following characteristics:

1. Very strong corrosion resistance: The corrosion resistance of Galvalume Sheet is 6-8 times that of ordinary galvanized sheet, and it can usually be guaranteed to be rust-free for 20 years.

2. High temperature oxidation resistance: Galvalume Sheet will not change color or deform under long-term use at 315 degrees Celsius.

3. High heat reflectivity: The heat reflectivity of Galvalume Sheet is higher than 75%, which is about twice that of galvanized sheet. 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: Galvalume Sheet is a good base material for paint coating. The composite coating of alloy and organic matter can provide more efficient protection and corrosion protection.

6. More usable area: The specific gravity of Galvalume Sheet coating (3.75 g/m3) is much smaller than that of zinc coating (7.15 g/m3). Therefore, in the case of the same thickness of the steel substrate and coating, the use area of Galvalume Sheet per ton is much larger than that of Galvalized Sheet, 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 is some knowledge points about Galvalume Sheet, I hope to help you.
