Galvalume steel sheet is an alloy coated steel sheet widely utilized in many fields like building materials, home appliances, and ships. The galvalume steel sheet consists of aluminum-zinc alloy covering on the surface of the steel sheet, which consists of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at 600 ° C. the entire structure is made by aluminum-iron-silicon-zinc.

# Characteristic:

Galvalume steel sheets have many excellent properties:

Corrosion resistance

The corrosion resistance is especially thanks to the protective function of aluminum and zinc. When the zinc is worn, the aluminum forms a layer of dense alumina that forestalls the corrosion-resistant material from further corroding the inside .

# Heat resistance

The aluminum-zinc steel plate has good heat resistance and may withstand a heat of quite 300 degrees Celsius. it's almost like the heat oxidation resistance of the aluminum-plated steel sheet and is usually used.

Chimney tubes, ovens, illuminators and fluorescent shades.

# Heat reflective

Aluminized galvanized steel sheets have a high heat reflectivity, which is twice that of galvanized steel sheets, which are often used as insulation materials.

# Economic

Since the density of 55% of AL-Zn is smaller than the density of Zn, the aluminum-zinc steel sheet is larger than the world of the galvanized steel sheet by 3% or more within the case where the load is that the same as that of the gold-plated layer.

# Application:

Buildings: roofs, garages, walls, pipes and modular houses, etc.

Automobiles: muffler, pipe , wiper attachment, fuel tank, truck box, etc.

Home appliances: refrigerator backboard, gas stove, air conditioning , electronic microwave , LCD frame, CRT explosion-proof tape, LED backlight, electrical cabinet, etc.

Agricultural: pig houses, chicken houses, granaries, greenhouse pipes, etc.

Other: heat insulation cover, device , dryer, warmer, etc.
