Hot-dip galvanized steel can be painted to achieve any look you desire.*
The synergistic effect of the two coatings extends the service life for unparalleled corrosion protection.
The metallurgically bonded galvanized coating serves as an ideal primer providing an impervious barrier for the base steel.
Protecting steel from corrosion involves either the use of hot-dip galvanizing or some type of paint system. Corrosion specialists are now using both methods of corrosion protection in what is referred to as a duplex system. When paint and galvanized steel are used together, the corrosion protection is superior to either protection system used alone and can last from 1.5 to 2.5 times the combined lifetimes of both systems.
  This brochure provides an overview of procedures for successful adhesion of paint to HDG. Topics include why hot-dip galvanized steel is painted, benefits of duplex systems, pre-treating, surface preparation procedures, and recommendations for painting new or weathered surfaces -- in the shop or field.    

Painting galvanized steel requires careful preparation and a good understanding of both painting and galvanizing. Many products have been galvanized and painted successfully for decades, including automobiles and utility towers. Past experience provides excellent historical data for how best to achieve good adhesion. Click HERE for all the information you need to successfully paint hot-dip galvanized steel.
