ZAM Zn-Al-Mg Alloy Coated Solar Steel Profile – High Corrosion PV Grade
Product Overview
ZAM zinc-aluminum-magnesium alloy coated solar profile is the next-generation corrosion-resistant mounting material designed for harsh-environment solar projects. The ternary alloy coating delivers unique self-healing cut-edge corrosion protection, outperforming standard hot-dip galvanized steel in coastal, industrial and high-humidity solar installations. This grade extends mounting structure service life to match the 25+ year design life of modern photovoltaic power plants, reducing long-term maintenance and replacement costs.
Why Choose CNB ZAM Solar Steel?
We supply advanced ZAM alloy coated solar profiles from leading Chinese mills with patented alloy composition and coating technology. Every section undergoes strict corrosion testing including salt spray and cut-edge corrosion verification to guarantee performance in harsh environments. We offer both standard and high strength base grades with various coating weights to match specific project corrosion and load requirements.
