Why ZAM Is Skyrocketing in Solar Mounting Systems

Solar mounting systems need to stand strong for 25+ years—even in harsh weather. That’s why ZAM (zinc-aluminum-magnesium alloy steel) is rapidly becoming the top choice for PV projects worldwide. Its unique advantages solve key pain points of traditional materials, driving its growing popularity in the solar industry.

1. 5-10x Stronger Corrosion Resistance

ZAM’s Zn-Al-Mg coating delivers unmatched durability, outperforming hot-dip galvanized steel by 5-10 times . It resists red rust for 3,000+ hours in salt spray tests , making it perfect for coastal areas, high-humidity agri-PV farms, and industrial zones. With a 30+ year lifespan , it eliminates premature bracket replacement.

2. Game-Changing Self-Healing Edges

Cutting or punching traditional steel damages its protective layer, leading to rust. ZAM fixes this with self-healing technology—magnesium ions form a protective film on exposed edges , no post-processing needed. This saves time and costs for large-scale projects.

3. Lightweight, Strong, and Cost-Effective

ZAM is 30-50% lighter than traditional steel but just as strong , reducing transportation and installation costs. While upfront costs are slightly higher, zero maintenance needs over decades push total ownership costs down by 10%+ .

4. Eco-Friendly and Versatile

 Free of heavy metals , ZAM meets global green standards like EU REACH. It works for rooftop, ground-mounted, and carport PV systems , with standardized designs for quick assembly.

From Singapore’s 785kW rooftop projects to coastal solar farms, ZAM proves it’s more than a material—it’s a reliable, cost-saving solution for solar’s long-term needs. As the industry chases durability and ROI, ZAM’s popularity is only set to grow. Want to see how ZAM fits your next PV project? Reach out to trusted suppliers for tailored solutions!
