This specification covers deformed steel wire that has been cold
worked by drawing, rolling, or both drawing and rolling to be used
as produced, or in fabricated form, for the reinforcement of
concrete in sizes having nominal cross-sectional areas not less
than 6.45 mm2 [0.01 in.²].

Supplement S1 describes high-strength wire, which shall be
furnished when specifically ordered. It shall be permissible to
furnish high-strength wire in place of regular wire if mutually
agreed to by the purchaser and manufacturer.

The values stated in either SI units or inch-pound units are to
be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall
be used independently of the other. Combining values from the two
systems may result in nonconformance with the standard. The
inch-pound units are shown in brackets except in Table 1.
