Specifies requirements for the mass, quality and testing of galvanized coatings applied to ferrous open sections on all surfaces, except cut ends, using an in-line process that utilizes specialized equipment. Appendices give corrosion information, advice on transport and storage of galvanized products, requirements for the renovation of uncoated areas and methods for the determination of coating mass and local thickness.

This Standard specifies requirements for the mass, quality and testing of galvanized coatings applied to ferrous open sections on all surfaces except cut ends, using an in-line process that utilizes specialized equipment.Matters relating to the quality, properties, or dimensional requirements of the open sections are outside the scope of this Standard.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 Alternative means for determining compliance with this Standard are given in Appendix B.3 General information on factors that affect the corrosion of galvanized steel is given in Appendix C.4 Electroplated zinc coatings applied to steel strip for manufacture into open sections are not covered by this Standard. The application of this Standard to these coatings is subject to agreement between the purchaser and the supplier.
