Mounting systems treated with the zinc-aluminum-magnesium alloy coating surface process are referred to as zinc-aluminum-magnesium mounting systems. In recent years, zinc-aluminum-magnesium mounting systems have gradually emerged as a rising star in the industry, promoting environmental sustainability, cost-effectiveness, and the sustainable development of the mounting system sector.
1. Superior Corrosion Resistance: The coating of hot-dip zinc-aluminum-magnesium mounting systems contains alloying elements such as Al, Mg, and Si, significantly enhancing the corrosion inhibition effect of the coating. Compared to ordinary galvanized mounting systems, it achieves higher corrosion resistance with a lower coating adhesion, offering 10–20 times the corrosion resistance of hot-dip galvanized mounting systems.
2. Excellent Processability: Hot-dip zinc-aluminum-magnesium mounting systems are denser than traditional galvanized mounting systems,
making them less prone to coating peeling during stamping processes. They exhibit outstanding performance in stretching, stamping, bending, and welding under demanding conditions. Additionally, due to the high hardness of the coating, they possess remarkable wear resistance and damage tolerance.
3. Self-Healing Properties: The coating components near cut edges continuously dissolve, forming a dense protective film primarily composed of zinc hydroxide, basic zinc chloride, and magnesium hydroxide. This protective film has low conductivity and effectively inhibits corrosion at the cut edges.
4. Extended Lifespan: With corrosion resistance that is 10–20 times stronger than ordinary galvanized materials and the self-healing protective ability for cut edges, zinc-aluminum-magnesium mounting systems generally have a lifespan of up to approximately 50 years.
