    Abstract - (Show below) - (Hide below)

    Specifies requirements and tests for hot-dip zinc coatings on fabricated ferrous articles including structural steel, steel sheet fabrications, assembled steel products, fabricated tubes, fabricated wire work, steel forgings and stampings, ferrous castings and nails and other small components. Appendices give advice on the design of articles to be galvanized, on the transport and storage of galvanized articles and on general factors affecting the corrosion of the galvanized coating.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements and tests for hot-dip zinc coatings on fabricated ferrous articles including structural steel, steel reinforcements, steel sheet fabrications, assembled steel products, tubular fabrications, fabricated wire work, steel forgings, steel stampings, ferrous castings, nails and other small components.This Standard applies to both centrifuged and non-centrifuged articles.This Standard does not apply to products such as wire and welded wire fabric (see AS/NZS 4534), sheet (see AS 1397) or open sections (see AS/NZS 4791) and tube hot-dip galvanized in continuous, semi-continuous or specialized plants (see AS/NZS 4792).NOTES:1 Advice and recommendations on information to be supplied by the purchaser to the hot-dip galvanizer at the time of enquiry or order are contained in the purchasing guidelines set out in Appendix A.2 Means for demonstrating compliance with this Standard are given in Appendix B.3 After-treatment of hot-dip galvanized articles is not covered by this Standard. Such treatment (if any) should be specified separately by the purchaser.
