In the past two years, galvanized aluminum-magnesium materials have been widely favored in solar panel mount.Do you know the anti-corrosion principle of galvanized aluminum-magnesium?

1.Hot-dip plating technology

The galvanized aluminum-magnesium solar bracket adopts hot-dip plating technology to form a uniform and dense zinc-aluminum alloy protective layer on the surface of the bracket. This protective layer can effectively prevent oxidation and corrosion on the surface of the stent, thereby extending the service life of the stent.

2.Adding alloying elements

Al, Mg and other alloying elements are added to the coating of galvanized aluminum-magnesium steel plates. These elements improve the corrosion resistance of the coating. Compared with traditional galvanized products, the coating has less adhesion, but can form a dense protective film on the surface to achieve better corrosion resistance. Its corrosion resistance is 10-20 times that of traditional hot-dip galvanized sheets.

3.Self-healing cutting surface

The coating components around the self-healing cutting surface continue to dissolve, forming a dense protective film mainly composed of zinc hydroxide, alkaline zinc chloride-based magnesium hydroxide, etc. This protective film has low conductivity and is harmful to The corrosion resistance of the cutting surface is inhibited, and it has the ability to repair sections and scratches.

4.Good electrical conductivity

Zinc-aluminum-magnesium solar mounting system have excellent electrical conductivity, so they can better conduct weak currents generated by various reasons in the photovoltaic bracket system.

5.Longer life

Due to the super corrosion resistance and the corrosion-resistant self-healing effect of the cut section, components made of hot-dip galvanized aluminum-magnesium steel plate alloy-coated plates have a longer service life. Under the same coating, magnesium-aluminum-zinc plating is used The life span can reach more than 30 years.

6.Easy to process

The coating of hot-dip galvanized aluminum-magnesium steel sheets is denser than traditional hot-dip galvanized sheets, so it is not easy to peel off the coating during stamping processing. It has excellent processing properties such as stretching, stamping, bending, and welding under severe conditions, and due to the high hardness of the coating, it has excellent damage resistance.
