Hot-Dip Galvanizing

Duplex Coatings

A Duplex System is the combination of two protective coating systems: a paint applied as a topcoat to a galvanized coating. ‘Duplex’ coatings of galvanizing-plus-paint are often the most economical solution to protecting steel in highly corrosive environments.

Such systems provide a synergistic effect in which the life of the combined coatings exceeds the total life of the two coatings if they were used alone. A galvanized coating under a paint system will eliminate early rusting at damaged areas. The galvanized coating protects the base steel, supplying cathodic and barrier protection so rust will not grow and paint will not peel up. Paint in turn grants barrier protection to the galvanized coating. The paint slows down the rate at which the zinc is consumed, greatly extending the life of the galvanized steel.
