Corrosion Protection

Protective Coatings Overview

From hot dip galvanizing milk containers in the late 1890's to creating a patented process in the 1970's for painting galvanized metal (Colorgalv®), Duncan Galvanizing provides state-of-the-art hot dip galvanizing and high-performance architectural finishes for ANY metal substrate, including galvanized steel, aluminum and "black steel" (uncoated steel).

Our value added processes will enhance the look of any project while providing long-term corrosion protection. Since we don’t manufacture paint or powder, we use only those companies whose products are suitable for the particular application, meet all environmental requirements, are sustainable, and have unlimited color choices.

What should you choose?

There are many forms of corrosion protection out there, ranging from zinc-rich paint to hot-dip galvanizing. Even within hot-dip galvanizing, there are many options depending on your needs.
