Product Introduction
CNB Group supplies advanced Zn‑Al‑Mg alloy coated steel (ZAM), offering corrosion resistance 5‑10 times better than standard galvanized steel. The magnesium in the coating creates a stable, self‑healing film that protects cut edges and scratches. It outperforms GI in stamping (lower friction coefficient) and welding (wider welding window). Available in thicknesses 0.15‑6mm and widths up to 1600mm, it serves photovoltaic mounting systems, agricultural greenhouses, highway guardrails, automotive body parts, and high‑end construction. Grades range from DC51D+ZM to high‑strength HC340LAD+ZM and dual‑phase steel.
