High-durability ZAM coated steel coil delivers 5-10x greater corrosion protection than standard galvanized steel. Engineered with auto cut-edge self-healing technology for solar PV mounting, automotive structural frames, and heavy coastal construction.
Extreme Corrosion Resistance
Self-Healing Cut Edges
Superior Formability
Zn-Al-Mg coating creates dense film protecting against harsh marine & industrial environments. / Высокая коррозионная стойкость в агрессивных средах.
Magnesium migration automatically repairs sheared edges, drilled holes, and scratches over time. / Самовосстановление кромок при резке и перфорации.
Excellent deep-drawing, bending, and stamping performance with reduced coating friction. / Отличная штампуемость и гибка без отслаивания.
