This Standard specifies requirements for the chemical composition and the mechanical and geometrical properties of reinforcing steel used for the reinforcement of concrete in the form of-
(a) deformed or plain bars and coils;
(b) machine-welded mesh; and
(c) continuously threaded bars.
This Standard does not apply to prestressing steels, stainless steel reinforcement, epoxy-coated steels and galvanized steels.

NOTES:
1. Means for demonstrating compliance with this Standard are given in Appendix A.
2. Prestressing steels are covered by AS 1310, AS 1311, AS 1313.
3. Information on stainless steel reinforcement may be found in other internationally (accepted) Standards such as BS 6744 or ASTM A955M.

Sets out specifications for Australian and New Zealand Steel reinforcing materials (bars, coils and welded mesh). Requirements for chemical, mechanical and physical properties for three different strength grades and the three different ductility classes are also covered.
