This Standard specifies requirements for the classification, mass, quality and testing of zinc coatings on welded hollow steel sections and on open steel sections produced from electrogalvanized strip. Matters relating to the quality, properties, or dimensional requirements of the basis steel sections are outside the scope of this Standard. NOTES: 1 Advice and recommendations on information to be supplied by the purchaser at the time of enquiry or order are contained in the purchasing guidelines set out in Appendix A. 2 Alternative means for determining compliance with this Standard are given in Appendix B. 3 For requirements for the basis metal of hollow sections see relevant product Standards, e.g. AS 1074 and AS 1163. 4 General information on factors that affect the corrosion of zinc coated steel is given in Appendix C. 5 In this Standard, hollow and open sections will be referred to as ‘sections’ unless circumstances require clarification.
