Aluminum-Zinc Coated Plate

Aluminum-zinc plated steel sheet has a characteristic smooth, flat and ornate starburst surface with a silver-white base color. The special coating structure gives it excellent corrosion resistance. Aluminum-zinc-plated plate normal service life of up to 25a, heat resistance is very good, can be used for 315 ℃ high temperature environment; plating and paint film adhesion is good, has good processing performance, can be stamping, shearing, welding, etc.; surface conductivity is very good.

Characteristic

1. Heat reflectivity:

Aluminum-zinc-plated steel sheet has a high thermal reflectivity, which is twice that of galvanized steel sheet, and is often used as a heat-insulating material.

2. Heat resistance:

Aluminum-zinc alloy steel sheet has good heat resistance, can withstand high temperatures of more than 300 degrees Celsius, and aluminum-plated steel resistance to high-temperature oxidation is very similar, often used in chimney pipes, ovens, lighting and fluorescent lamps cover. Corrosion Resistance:

The corrosion resistance of aluminized zinc coils is largely due to aluminum, which protects. When the zinc is abraded, the aluminum forms a dense layer of aluminum oxide, which prevents the corrosion-resistant material from further corroding the interior.

3. Economy:

Because the density of 55% AL-Zn is smaller than that of Zn, the area of Aluminum-Zinc Plated Steel Sheet is more than 3% larger than that of Galvanized Steel Sheet in the case of the same weight and the same thickness of plating layer.

4. Easy to paint

Aluminum-zinc-plated steel sheet has excellent adhesion to paint and can be painted without pretreatment or weathering.

The paint adhesion of the gold-plated layer of the aluminum-zinc-plated steel sheet is excellent, so it can be directly coated on advertising boards and general-use boards without pretreatment such as Weathering.

5. Aluminum-zinc-plated steel sheets have a gorgeous silver-white surface.

6. Aluminum-zinc plated steel sheets have similar processing and coating properties as galvanized steel sheets.
