Register today for a FREE Webinar on Selection of Coatings over Galvanizing sponsored by AZZ Galvanizing and Sherwin-Williams

Hot-dip galvanizing consists of a layer of zinc applied over a steel substrate to provide corrosion protection to the underlying steel and offers effective long-term corrosion protection for steel in chemically neutral atmospheric service.  However, in service environments where rapid depletion of the zinc (galvanized) layer can occur, protective coatings are frequently applied over the galvanized surface to provide a more effective corrosion protection system.

Protective coatings are also used to overcoat aging and deteriorating galvanizing to restore corrosion protection to steel no longer fully protected by the sacrificial zinc (galvanized) layer. Overcoating allows a variety of finish colors to be applied to galvanized surfaces for safety, identification and aesthetic purposes.

This webinar will explain selection of coatings for use over galvanized steel by following the steps below:

1. Determine the service environment for the coating to be applied

2. Determine the condition of the galvanized steel over which the coating will be applied

3. Select an appropriate coating or coating system based on the service environment and the current condition of the galvanized steel

4. Refer ASTM D6386, Standard for Preparation of Zinc (Hot Dip Galvanized) Coated Iron and Steel Product and Hardware Surfaces for  Painting for guidance regarding preparation of galvanized substrates prior to coating application
