This Standard specifies requirements for plain and deformed hot-rolled bars for use as reinforcement for concrete. It applies to reinforcement supplied in straight lengths or in coil form. The following significant changes to the previous edition have been made: fabrication requirements have been amended to comply with AS 3600 and tolerances on straightness of reinforcing bars have been added.

This Standard specifies requirements for plain and deformed hot-rolled steel bars for use as reinforcement for concrete. It applies to reinforcement supplied in straight lengths or in coil form. For coiled material, the requirements apply to the straightened product.NOTES:For 'Purchasing Guidelines', see Appendix A.For 'Means for demonstrating compliance with this Standard', see Appendix B.For welding of bars complying with this Standard, see AS 3600 and AS 1554.3.This Standard is not applicable to prestressing steels.
