Specifies requirements for the production and supply of hot-rolled structural steel bars and sections for general structural and engineering applications.

This Standard specifies the requirements for the production and supply of hot-rolled structural steel bars and sections. For general structural and engineering applications, all grades specified in this Standard are suitable for -(a) welding in accordance with AS/NZS 1554; or(b) riveting and bolting as specified in AS 1538, AS 3990, AS 4100 and NZS 3404.This Standard does not cover the following:(i) Structural steel - hot-rolled plates, floorplates and slabs (see AS/NZS 3678), and welded I sections (see AS/NZS 3679.2).(ii) Steel plates for pressure equipment (see AS 1548).(iii) Structural steel hollow sections (see AS 1163).(iv) Carbon steels and carbon-manganese steels -hot-rolled bars and semifinished products (see AS 1442).(v) Steel reinforcing bars for concrete (see AS 1302).(vi) Structural and pressure vessel steel- Quenched and tempered plate (see AS 3597).NOTES:1 Guidelines to purchasers on requirements that should be specified by the purchaser and those that should or may be agreed on at the time of enquiry and order are given in Appendix A.2 Guidelines to various means for demonstrating compliance with this Standard are given in Appendix B.3 Guidelines on cold-bending of rounds, flats and squares during fabrication are given in Appendix C.
