Galvanize It! Online Seminar

Summary: The Best of Both Worlds

A successful duplex system begins at the drawing board. By communicating with the galvanizer upfront, he/she can avoid any treatments that would impede paint/powder adhesion. Communication before the project begins can help determine the division of responsibilities by deciding who is responsible for each step of the process. This can eliminate mistakes and omissions when powder coating over galvanized steel.

In addition to what the galvanizer can control, it is imperative to properly identify the surface condition, and follow the appropriate cleaning steps for that surface condition. Finally, profiling the surface and selecting paint formulations compatible with zinc coatings will provide a successful duplex system.

Why use a Duplex System?

  • Duplex systems provide corrosion protection + endless color choices for aesthetics
  • The synergistic effect between hot-dip galvanizing and paint/powder coatings mean longer life and less maintenance
  • Specifying duplex systems is simple, but requires communication and clear division of responsibility
  • Properly identifying and preparing the surface are critical to a successful duplex system
