ZINC MAGNESIUM (ZM)

A Zinc Magnesium (ZM) finish is produced via a hot dip galvanising molten bath with a zinc-based composition, which includes Aluminium and Magnesium. Thanks to its composition a Zinc Magnesium finish provides excellent surface and cut-edge corrosion protection, even in hostile environments such as high temperatures, humidity and those prone to salt or chemical corrosion. In particular a Zinc Magnesium finish provides superior corrosion protection for electrical equipment, making it ideal for data centres. Where a hot dip galvanised steel finish is porous, a Zinc Magnesium finish is uniform and impermeable. A Zinc Magnesium finish also has a self-repairing property that causes a protective film to form around surface edges, weld seams and scratches. Read more
