Prime Full Hard G550 Aluminum Zinc Steel Coil Galvalume Steel Coil Az150 GL Coils
Galvalume coil is a kind of color-coated steel plate with zinc as the base and aluminum as the surface coating, which is made by cold rolling or hot rolling.
Product Introduction
Galvalume coil is an alloy material, mainly composed of aluminum (55%), zinc (43.4%) and silicon (1.6%) solidified at 600℃ to form a dense quaternary crystal. It has many excellent properties, including:
Corrosion resistance: The corrosion resistance of galvanized coil is three times that of pure galvanized coil. When zinc is worn, aluminum forms a dense layer of aluminum oxide to prevent further corrosion.
Heat resistance: Galvalume coil can withstand temperatures up to more than 300 degrees Celsius, similar to the high-temperature oxidation resistance of aluminum-plated steel sheets, and is often used in high-temperature environments such as chimney pipes, ovens, lighting fixtures and fluorescent lamp covers.
Thermal reflectivity: Its thermal reflectivity is twice that of galvanized steel sheets, and it is often used as insulation materials.
Economical efficiency: Since the density of 55%AL-Zn is lower than that of Zn, the area of galvanized coil is more than 3% larger than that of steel coil at the same weight and the same thickness of the gold coating.
Easy processing: Galvalume coils are easy to process and can be installed by drilling, pasting, etc. to meet the requirements of different occasions.

Product Application
Aluminum-zinc coils reproduce excellent performance and are widely evaluated in multiple fields, including but not limited to:
Construction field: Aluminum-zinc coils are often used in roofs, walls, garages, residential walls, pipes and modular houses, etc. Their corrosion resistance and weathering resistance can effectively protect the surface wall of the building from natural environmental monitoring.
Automobile field: Aluminum-zinc coils can be used to manufacture automobile mufflers, exhaust pipes, wiper accessories, fuel tanks, truck boxes and other parts to improve the safety and service life of the car.
Home appliance field: Aluminum-zinc coils are suitable for the manufacture of refrigerator back panels, gas stoves, air conditioners, electronic drying and other home appliances. Their surface coating performance and anti-rust ability make the products more beautiful and durable.
Agricultural field: Aluminum-zinc coils are used in the construction of agricultural facilities such as pig houses, chicken houses, granaries, and greenhouse pipes.
In summary, the unique alloy composition and excellent performance of aluminum-zinc coils play an important role in many fields such as construction, automobiles, home appliances and agriculture.
