Galvanized Corrugated Sheet

Aluzinc coated roofing sheet is an alloy coated steel plate widely used in building materials, home appliances, automobiles, environment, machinery, ships and other fields. The aluminum-zinc alloy coating is composed of 55% aluminum, 43.4% zinc and 1.6% silicon, solidified at 600°C. The entire structure is an aluminum-iron-silicon-zinc alloy coated steel sheet, forming a dense quaternary crystal structure.

Because of its Many Excellent Characteristics

• Corrosion resistance: The corrosion resistance of aluminized steel coils is mainly due to the protective function of aluminum. When zinc is subjected to wear, aluminum forms a dense layer of alumina that prevents further corrosion.
• Heat resistance: The Al-Zn alloy steel sheet has good heat resistance and can withstand high temperatures above 300°C. It is often applied to chimneys, ovens, illuminators and fluorescent lampshades.
• Thermal reflectivity: The sheet has high thermal reflectivity, twice as much as galvanized steel, and is often used as heat insulating material.
• Economical efficiency: Since the density of 55% Al-Zn alloy is lower than that of zinc, the sheet covers 3% more area than galvanized steel sheet of the same weight and thickness.

Applied In

• Buildings: roofs, garages, walls, pipes, and modular homes
• Cars: muffler, exhaust pipe, windshield wiper accessories, fuel tank, truck case, etc.
• Home appliances: refrigerator back board, gas stove, air conditioner, microwave oven, LCD frame, CRT anti-explosion belt, LED backlight, electric cabinet, etc.
• Agriculture: pig house, chicken house, granary, greenhouse pipes, etc.
• Others: thermal insulation cover, heat exchanger, dryer, water heater, etc.
