In the mid 1960's, Duncan Galvanizing recognized the architectural possibilities that painting galvanized steel could bring to the building community. We carefully researched, tested and then patented the Colorgalv process under US Patent No. 5641543. The result? We became the first galvanizer in North America to successfully paint hot dip galvanizing.

Since 1963, Colorgalv has been the gold standard for factory applied high performance architectural coatings. Available in any color and warranted for twenty years against rust, Colorgalv provides the architectural and engineering community in the Northeast with a long lasting metal finishing system that blends protective coatings with the aesthetics of architectural finishes.

Under the Colorgalv family, there are a variety of products based on the performance and warranty you need (for instance, you can add a clear-coat for anti-graffiti protection to any of these below as a "Plus". Click Here For Comprehensive Guide
