Zinc Plating

Zinc Plating

This procedure covers electrodeposited zinc coatings applied to iron or steel articles to protect them from corrosion. The coatings are provided in four standard thickness classes, in the as-plated condition or with one of three types of supplementary finish.

  • Corrosion resistance
  • Bright or dull finish

Zinc Plating Capabilities

Type of Plating
Zinc Plating/Zinc Coating, Electrodeposited
Primary function is to rust proof steel or iron. Can have a bright finish resembling Chromium, or a dull finish.
Process Approvals
For Zinc Plating we adhere to:
This specification covers requirements for electrodeposited zinc coatings applied to iron or steel articles to protect them from corrosion.
Base Materials Worked
This specification focuses on zinc plating of Iron and Steel.
Plating Type
Zinc plating covered by ASTM B633 shall be of the following Types:
  • Type I = Without supplementary chromate or phosphate treatment
  • Type II = With supplementary chromate treatment
  • Type III = With supplementary phosphate treatment
Plating Class
Plating thickness depends on the Class Required:
  • Class 1 = 0.0010" thick (min.)
  • Class 2 = 0.0005" thick (min.)
  • Class 3 = 0.0002" thick (min.)
All zinc plating processes are performed manually to ensure the proper care is given to each step.
