Standards for Galvanized Products

Galvanized products should be specified in accordance with the appropriate national standards, which have been drawn up to provide minimum standards to ensure optimum performance of galvanized products and to give guidance in selection, application, and design. AS/NZS 2312 ‘Guide to the protection of structural steel against atmospheric corrosion by the use of protective coatings’ is a particularly valuable reference in the selection of the most practical, economic coating in particular applications.
