The surface of aluminized zinc coil is unique smooth, flat and gorgeous star flower, and the base color is silver white. Special coating structure makes it have excellent corrosion resistance. The normal service life of the aluminized zinc plate can reach 25A, and the heat resistance is very good. It can be used in the high temperature environment of 315℃. Coating and paint film adhesion is good, has good processing performance, can be stamping, cutting, welding, etc.Surface conductivity is also very good.

The 55% al-Zinc-coated al-zinc-plated steel coil has better corrosion resistance than the galvanized steel coil of the same thickness when both sides are exposed to the same environment. The 55% al-Zinc-coated al-zinc-coated steel plate not only has good corrosion resistance, but also has excellent adhesion and flexibility.

The Specialty of Aluminum Zinc Coated Coil |
|
|
Reflect Heat
|
Aluminium-zinc steel coil has a high thermal reflectivity, twice that of galvanized steel plate, and is often used as an insulating material. |
|
Heat resistance |
Aluminum zinc alloy steel plate has good heat resistance, can withstand the high temperature of more than 300 degrees Celsius, and aluminum plated steel plate high temperature oxidation resistance is very similar, often used in chimney tubes, ovens, illuminators and solar lampshades. |
|
Corrosion resistance |
The corrosion resistance of aluminium-zinc steel coil is mainly due to aluminum, aluminum protection function. As the zinc wears away, the aluminum forms a dense layer of aluminum oxide that prevents corrosion resistance from further corroding the interior. |
|
Economical efficiency |
The density of 55% Al-Zn is less than that of Zn, so the area of aluminized zinc plate is more than 3% larger than that of galvanized steel plate under the condition of the same weight and the same thickness of gold plating. |
|
Easy to paint on |
The aluminized zinc plate has excellent adhesion to the paint and can be painted without pretreatment and weathering. |
|
Aluminum - zinc plated steel coil has an ornate silver - white surface.It has similar processing and spraying properties to galvanized steel plate |
