hot dipped galvalume steel coil sheet DX51D+AZ
Hot Dipped Galvalume Steel Coil
The hot dipped galvalume steel coil has a smooth, flat and stunning star flower surface. The base colour is silver-white.
The production process of hot-dipped galvalume steel coil is similar to that of galvanized steel sheets and aluminum-coated sheets, and is a continuous molten coating process.
Galvalume steel sheets with 55% aluminium-zinc alloy coating have superior corrosion resistance compared to galvanized steel sheets of the same thickness when both sides are exposed to the same environment.
The colour-coated product made from galvanized steel plate with 55% aluminium-zinc alloy coating boasts excellent adhesion and flexibility in addition to good corrosion resistance.

1. Heat reflectivity
2. Heat resistance
The galvalume steel plate has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It is very similar to the high-temperature oxidation resistance of aluminized steel plates. It is often used in chimney pipes, ovens, luminaires and fluorescent lampshades.
3. Corrosion resistance
The corrosion resistance of galvalume steel coils is primarily due to the protective function of aluminum. When zinc is worn, aluminium forms a dense layer of aluminium oxide, preventing corrosion-resistant substances from further corroding the interior.
4. Economy
Because the density of 55% AL-Zn is smaller than that of Zn, when the weight is the same and the thickness of the gold plating layer is the same, the area of the galvanized steel plate is more than 3% larger than that of the plated steel plate.
5. Easy to paint
Galvalume has excellent adhesion to paint and can be painted without pre-treatment and weathering.
6. The galvanized steel plate has a gorgeous silver-white surface.
7. Al-zinc-coated steel plates and galvanized steel plates have similar processing performance and spraying performances.
