Characteristics of galvalume

1. Heat reflectivity:

The heat reflectivity of galvalume steel sheet is very high, which is twice that of galvanized steel sheet. People often use it as a material for heat insulation.

2. Heat resistance:

Aluminum-zinc alloy steel plate has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It is similar to the high-temperature oxidation resistance of aluminum-plated steel plate.

The corrosion resistance of galvalume steel coil is mainly due to the protective function of aluminum and aluminum. When zinc is worn, aluminum forms a dense layer of aluminum oxide, which prevents corrosion-resistant substances from further corroding the interior.

3. Economy:

Because the density of 55% AL-Zn is lower than that of Zn, the area of the galvalume steel sheet is more than 3% larger than that of the galvanized steel sheet with the same weight and the same thickness of the gold coating.

4. Easy to paint

The aluminum-zinc plate has excellent adhesion between the paint and the paint can be painted without pretreatment and weathering.

The coating adhesion of the gold-plated layer of aluminum-zinc steel plate is relatively good, so it can also be directly coated on advertising boards and general boards without pre-treatment such as weathering.

5. The galvalume steel sheet has a gorgeous silver-white surface.

6. The galvalume steel sheet and the galvanized steel sheet have similar processing performance and spraying performance.
