Standard Specification for Steel Wire for Masonry Joint Reinforcement


Specification covers masonry joint reinforcements fabricated from cold-drawn steel wires. It specifies that joint reinforcement consists of longitudinal wires welded to cross wires. Wire used in the manufacture of masonry joint reinforcement shall be round. Masonry joint reinforcement shall then be assembled by automatic machines or by other suitable mechanical means that will assure accurate spacing and alignment of all members of the finished product. Longitudinal and cross wires shall be securely connected at every intersection by an electric-resistance welding process and then it shall be deformed. Tension, weld shear strength, and bend tests shall be performed on the samples. When corrosion protection of joint reinforcement has been provided, it shall be either zinc coated mill or hot-dip galvanized.


1.1 This specification covers masonry joint reinforcement fabricated from cold-drawn steel wire. Joint reinforcement consists of longitudinal wires welded to cross wires.

1.2 The values stated in inch-pound or SI units are to be regarded as standard. Within the text the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values may result in nonconformance with the specification.
