ZAM (Zinc–Aluminium–Magnesium Coated Steel)

ZAM is an advanced metallic coated steel featuring a Zinc–Aluminium–Magnesium alloy coating. The addition of magnesium enables a unique self-healing corrosion protection mechanism, particularly at cut edges, punched holes, and scratched areas.

Compared to conventional galvanized steel, ZAM offers significantly superior corrosion resistance, longer service life with thinner coating, and reduced maintenance costs. It is especially suitable for aggressive, outdoor, and industrial environments.

Standards: EN 10346 / JIS G3323 / ASTM (Equivalent)
