Performance Comparison of Structural Steel Coating Systems

For the last twenty years, the Ohio Department of Transportation (ODOT) has primarily specified the use of the Three Coat Organic Zinc primer coat, Epoxy intermediate coat and Urethane finish coat (OZEU) system for the corrosion protection and aesthetic enhancement of structural steel. When the steel is prepared and the paint is applied properly, the three coat system has performed well. Paint manufacturers have developed new technology alternatives to the conventional three coat painting systems. ODOT needs to make sure the most cost effective methods are being used to extend the service life of its infrastructure assets. This research will investigate if the Two Coat Organic Zinc and Polysiloxane Structural Steel Coating Systems would be quicker to apply than the Three Coat Organic Zinc, Epoxy and Urethane (OZEU) Structural Steel Coating Systems, and if they can perform as well or better in protecting structural steel from corrosion, while retaining gloss and color.
