Corrosion Resistant Zinc-Aluminum-Magnesium Coated Steel with Scratch Resistance and Excellent Formability for Automotive Panels
Zinc aluminum-magnesium coated steel is a new type of corrosion-resistant coated steel sheet consisting mainly of zinc, about 11% aluminum, 3% magnesium and trace amounts of silicon.
Z-A-M is a highly corrosion-resistant hot-dip Zinc-Aluminum-Magnesium alloy coated steel sheet. Due to the effects of magnesium and aluminum, Z-A-M has excellent corrosion resistance, scratch resistance and formability.

Zn-Al-Mg alloy-coating are composed of Zn-2.0% Al-1.5%Mg. The products can be used in construction, household appliances and automotive industries.
Zn-Al-Mg alloy-coating products specifications: 0.4-2.5mm × 1000-1600mm
Coating thickness: 60-450g/m² (Both sides)
Surface treatment: Passivation, fingerprint resistant, oiled
Corrosion resistance of Zn-Al-Mg coating steel is significantly better than that of GI.
