Duplex Plating

What is Duplex Plating

Duplex plating is a two-step layering process that enhances performance properties.

Substrates For Duplex Plating

Industrial hard chrome plating can be applied to a wide variety of materials (substrates) including:

  • Stainless Steel
  • Cast Iron
  • Aluminum, for which we have a dedicated line
  • Copper
  • Bronze
  • Nickel
  • Steel

Our Production Capabilities

Production capabilities for duplex plating varies between processes. Please call our sales department with your specific request.

From start to finish, we understand that every step of the production process is critical to achieving the standards both we and our customers expect. That’s why we can also provide pre- and post-plating services upon request such as abrasive blasting, buffing and polishing, centerless belt-sanding, and stripping. See Extended Services for a complete list.
