What is Galvanic Action?

When zinc and steel are in direct contact with moisture, zinc becomes anodic and steel cathodic. The result is the preferential corrosion of the zinc and the protection of steel. In other words, the zinc sacrifices itself to corrosive elements to preserve the steel. Therefore, unlike the "skin" protection of all types of paint products, galvanic action does not depend on the integrity of a continuous film to prevent rust and corrosion. Even if scratched, a zinc-coated surface will continue to protect by slow sacrificial action as long as any zinc remains in the immediate area. Zinc-rich coatings, like those offered by Brite Products, have been proven to provide efficient galvanic action to combat rust and corrosion.
