DX51D+AZ Galvalume steel sheet
The surface of the Galvalume steel coil is uniquely smooth, flat and gorgeous star flower, and the base color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of aluminum-zinc plate can be up to 25a, and it has good heat resistance and can be used in a high temperature environment of 315°C; the adhesion of the coating and the paint film is good, and it has good processing properties, and can be punched, cut, welded, etc.; The surface conductivity is very good.
The coating composition is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon in weight ratio. The production process of galvanized steel sheet is similar to that of galvanized steel sheet and aluminized sheet, and it is a continuous molten coating process. The galvanized steel sheet with 55% aluminum-zinc alloy coating has better corrosion resistance than galvanized steel sheet of the same thickness when exposed to the same environment on both sides. The 55% aluminum-zinc alloy coated aluminum-zinc steel sheet not only has good corrosion resistance, but also the color-coated products have excellent adhesion and flexibility.

DX51D+AZ Galvalume steel sheet Features
1. Heat reflectivity:
The heat reflectivity of galvanized 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 very similar to the high temperature oxidation resistance of aluminized steel plate. It is often used in chimney pipes, ovens, luminaires and fluorescent lampshades. Corrosion resistance:
The corrosion resistance of galvanized steel coil is mainly due to the protective function of aluminum and aluminum. When zinc is worn out, 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 galvanized 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 sheet is relatively good, so it can also be directly coated on advertising boards and general boards without pre-treatment such as weathering.
5. The galvanized steel sheet has a gorgeous silver-white surface.
6. The galvanized steel sheet and the galvanized steel sheet have similar processing performance and spraying performance.

DX51D+AZ Galvalume steel sheet Production process
first step:
Pre-treatment: After the cold-rolled coil comes to the galvanizing workshop, after passing through the uncoiler, it passes through the degreasing section and reduction furnace to clean the steel coil and reduce its composition to the extent that it can be galvanized.
The second step:
Central section: The most critical technique is this step. After the zinc pot, a layer of zinc is plated on the surface of the steel plate. After coming out of the zinc pot, it becomes beautiful and atmospheric, and then it is cooled and shaped by the cooling tower, and Cinderella becomes The beautiful princess.
third step:
Post-processing: After a variety of processes, the steel plate finally comes to the post-processing stage. After smoothing, stretching, and passivation, the steel plate is finally rolled on the winder to form our final product.
The corrosion resistance of 55% galvanized steel is 2 to 6 times that of galvanized steel. Because of its superior corrosion resistance and processing performance, it can be directly used as building roof panels, civil and home appliances back panels, etc. It is also widely used For color coated substrates. The smooth commissioning of the galvanized sheet has not only enriched the company's product categories, but also provided more flexible options for future market layout and strategic planning.
