🔬 ZAM Coated Steel: The Next-Generation Coating That Outperforms GI by 5-12x – CNB Group Has ZM600 in Stock

Created on 08.31
If you are still using traditional galvanized steel (GI) for coastal projects, solar mounting systems, or agricultural buildings, you are missing out on a revolution.
ZAM (Zinc-Aluminum-Magnesium) coated steel is the fastest-growing segment in the coated steel market. With a unique alloy composition of Zn-(2-11%)Al-(1.5-3%)Mg, ZAM delivers 5 to 12 times the corrosion resistance of traditional GI – and CNB Group is the first Chinese manufacturer to produce ZM600 coating.
Why ZAM is replacing GI in demanding applications:
✅ Cut-edge self-healing – When the sheet is cut or scratched, the exposed edge forms a protective layer (Zn₅(OH)₈Cl₂·H₂O) that seals the cut and prevents corrosion from spreading. GI simply rusts.
✅ Superior salt spray performance – ZAM275 withstands 1,400+ hours before red rust appears, while standard Z275 GI fails before 500 hours. ZM600 extends this even further.
✅ Lower friction coefficient – Better formability, less die wear, and fewer surface defects during stamping and profiling – meaning lower production costs.
✅ Excellent weldability and paint adhesion – Compatible with standard welding and coating lines without process changes.✅ Ammonia resistance
 – ZM180 has far superior resistance to ammonia exposure compared to GI Z180, making it ideal for livestock and agricultural buildings.
