Comments
Australian/ New Zealand Standard AS/NZS 2312 Guide to the protection of structural steel against atmospheric corrosion by the use of protective coatings provides guidelines for selection and specification of coating systems for corrosion protection of structural steelwork. The designer can choose from a selection of systems based on exposed service life to first maintenance for various environments. AS/NZS 2312 has recently undergone a major update. Galvanizing and metal spraying have now become separate standards. A short summary of the major changes to AS/NZS 2312 and use of the standard is provided.
