ZAM
Zinc-Aluminium-Magnesium Coated Steel
ZAM — Zinc + Aluminium + Magnesium
Manufacturing Process
-
1
Surface Preparation (Surface Preparation)
Chemical wash or sandblast and acid treatment to prepare the surface
-
2
Hot-Dip Zinc Alloy Bath (Hot-Dip Zinc Alloy Bath)
Dip in Zn+Al+Mg molten bath at ~450°C under strict quality control
-
3
Cooling (Cooling)
Cool to allow the alloy coating to solidify and bond firmly
Properties
-
Superior Corrosion Resistance
Better resistance to salt water and chemicals than conventional galvanized steel
-
Wear Resistance
Magnesium enhances resistance to abrasion and wear
-
Self-Healing
The ZAM coating can self-repair minor scratches, extending service life
Applications
-
Automotive Industry — Vehicle frames and components requiring corrosion and wear resistance
-
Construction Industry — Building structures, bridges, and roofing in harsh environments
-
Home Appliance Industry — Refrigerators, washing machines, and electronics
-
Agricultural Industry — Greenhouse structures and equipment exposed to variable conditions
-
Energy Industry — Power plant equipment and pipeline systems requiring high durability
Summary
ZAM steel offers superior corrosion and wear resistance. The hot-dip alloy coating combining zinc, aluminum, and magnesium outperforms conventional galvanizing, and its self-healing property further extends service life.
