DX51D+AZ aluminum-zinc-plated materials, as a high-performance alloy-coated steel plate, have the following properties

1. Corrosion resistance
DX51D+AZ aluminum-zinc-plated materials have extremely strong corrosion resistance, which is mainly due to the aluminum-zinc alloy coating on its surface. When the zinc layer is worn, the aluminum will quickly form a dense aluminum oxide film, which effectively prevents the corrosive medium from further eroding the substrate. Therefore, DX51D+AZ aluminum-zinc-plated materials can still maintain good performance in harsh environments such as humidity and acid rain, and their normal service life can reach more than 25 years, which is 3-6 times longer than traditional galvanized sheets.

2. Heat resistance
Aluminum-zinc alloy has good heat resistance, and DX51D+AZ aluminum-zinc-plated materials can withstand high temperatures of more than 300 degrees Celsius without significant performance changes. This allows it to maintain good performance in high-temperature environments, such as chimney pipes, ovens, lighting fixtures, and fluorescent lamp covers.

3. Heat reflectivity
DX51D+AZ aluminum-zinc coating material has a high heat reflectivity, which is twice that of a galvanized steel sheet. This feature makes it an ideal thermal insulation material, which can effectively reduce the temperature inside the building and improve living comfort.

4. Economy
The density of aluminum-zinc alloy is lower than that of zinc, so under the same weight and coating thickness, the area of DX51D+AZ aluminum-zinc coating material is more than 3% larger than that of galvanized steel sheet, which has a higher cost performance.
