Zn-Al-Mg coated square

Zn-Al-Mg square and rectangular tubes are high-performance structural materials made from zinc-aluminum-magnesium coated steel sheets through cold forming. They offer excellent corrosion resistance and self-healing properties, making them ideal for photovoltaic mounting systems, steel structures, and outdoor construction.
Compared with traditional hot-dip galvanized tubes, they provide superior corrosion protection even at cut edges and welded areas, especially in harsh environments such as coastal or high-humidity regions.
