Aluminized zinc plate

Aluminized zinc steel plate surface is a unique smooth, flat and gorgeous star flower, the primary color is silver white. The 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 film adhesion is good, has good machining performance, can be stamping, shearing, welding, etc.; The surface conducts electricity very well.

The coating consists of 55% aluminum, 43.4% zinc and 1.6% silicon, respectively. The production process of aluminized zinc steel plate is similar to that of galvanized steel plate and aluminized plate in that it is a continuous melting plating process. Aluminum plated zinc steel plate with 55% aluminum zinc alloy coating has superior corrosion resistance compared with galvanized steel plate of the same thickness when both sides are exposed to the same environment. 55% aluminum zinc alloy plating aluminum zinc steel plate not only has good corrosion resistance, color coating products have excellent adhesion and flexibility.


1. Thermal reflectivity:

Aluminized zinc steel has a high thermal reflectance, twice that of galvanized steel, and is often used as a thermal insulation material.

2. Heat resistance:

Aluminum zinc alloy steel plate has good heat resistance, can withstand the high temperature of more than 300 degrees Celsius, and aluminum plating steel resistance to high temperature oxidation is very similar, often used in chimney tubes, ovens, illuminators and solar lampshades. Corrosion resistance:

Aluminum coated zinc steel coil corrosion resistance is mainly because of aluminum, aluminum protection function. When the zinc wears down, the aluminum forms a dense layer of aluminum oxide, preventing the resistance from further corroding the interior.

3. Economy:

Because the density of 55%AL-Zn is less than that of Zn, the area of the aluminized zinc sheet is more than 3% larger than that of the galvanized sheet, given the same weight and the same thickness of the gold coating.

4. Easy to paint

Aluminized zinc plate has excellent adhesion to paint and can be painted without pretreatment or weathering treatment.

The coating adhesion of aluminum-zinc plated steel plate is excellent, so the Weathering can also be directly applied on advertising boards and general boards without weathering.

5. Aluminized zinc steel plate has a silver-white gorgeous surface.

6. Aluminized zinc steel plate and galvanized steel plate have similar processing properties and spraying properties.
