GL Galvalumed Steel Coil made in China is an alloy coated steel sheet widely used in many fields such as building materials, home appliances, automobiles, environment, machinery, and ships. The galvalumed steel coil is covered by aluminum-zinc alloy on the surface of the steel plate, and is composed of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at 600 ° C.
The entire structure consists of aluminum-iron-silicon-zinc, an alloy-plated steel sheet forming a dense quaternary crystal.

Aluminized galvanized steel has many excellent properties:
Corrosion resistance: The corrosion resistance of “aluminum-plated steel coil” is mainly due to the protective function of aluminum and aluminum. When the zinc is worn, the aluminum forms a layer of dense alumina that prevents the corrosion-resistant material from further corroding the interior.
Heat resistance: Al-Zn alloy steel sheet has good heat resistance and can withstand temperatures of more than 300 degrees Celsius. It is similar to the high-temperature oxidation resistance of aluminized steel sheets, and is often used in chimney tubes, ovens, illuminators and fluorescent lamps.
Heat Reflectivity: wholesale galvalume steel coating steel coil has a high heat reflectivity, which is twice that of galvanized steel sheets, which is often used as insulation materials.
Economical Since the density of 55% of AL-Zn is smaller than the density of Zn, the aluminum-zinc-plated steel sheet is larger than the area of ​​the galvanized steel sheet by 3% or more when the weight is the same as the thickness of the gold-plated layer.

Application field of galvalumed steel coil
Buildings: roofs, garages, walls, pipes and modular houses, etc.
Automobiles: muffler, exhaust pipe, wiper attachment, fuel tank, truck box, etc.
Home appliances: refrigerator backboard, gas stove, air conditioner, electronic microwave oven, LCD frame, CRT explosion-proof tape, LED backlight, electrical cabinet, etc.
Agricultural: pig houses, chicken houses, granaries, greenhouse pipes, etc.
Others: heat insulation cover, heat exchanger, dryer, warm water, etc.
