Zinc

Zinc plating is the process of covering substrate metals (like steel and iron, etc.) with a layer or coating of zinc to protect the substrate from corrosion. Zinc plating prevents corrosion of protected metal by forming a physical barrier and acting as a sacrificial anode – even when this barrier is damaged.

Benefits of zinc plating:

  • Excellent corrosion resistance – up to 96 hours NSS 
  • Sacrificial coating
  • Cost effective
  • Normally has a chromate conversion layer to further assist in corrosion protection
