Zinc-Aluminium-Magnesium Alloy Coated Steel

Zinc-aluminum-magnesium alloy coated steel, normally known as Z.A.M steel is produced by coating the base material ( usually cold rolled steel ) in a bath consisting of specific composition of 3 elements, namely, zinc , aluminium and magnesium.

Models from different steel mills include

  • Superdyma from NSSMC
  • Posmac from Posco
  • Ecogal from JFE
Steel Rolls

  • Superior corrosion resistance as compared to hot dipped galvanized steel.
  • Superior corrosion resistance even on cut or slit edges.
  • Superior scratch resistance
  • “Self-healing” properties , where after surface is exposed, the material will form a special layer to prevent further corrosion.
  • Cost effectiveness of material due to longer durability in harsh conditions (Near the sea, out in extreme hot or cold climates and etc)
