Cold-reduced steel wire for the reinforcement of concrete and the manufacture of welded fabric

Scope: This document specifies technical requirements for cold-reduced steel wire designed for the reinforcement of concrete or for use in welded fabric. Two steel grades, CRB500 and CRB540H are defined as examples. Other grades can be used. This document is applicable to wire made from rod by working through dies or rollers. The production process is at the discretion of the manufacturer. For wire supplied in coil form, this document is applicable to the straightened product. Wires produced from finished products, such as plates and railway rails, are outside the scope of this document.
