ASTM A1064 / A1064M

1. Scope

1.1 This specification covers carbon-steel wire and welded wire reinforcement produced from hot-rolled rod to be used for the reinforcement of concrete. The steel wire is cold-worked, drawn or rolled, plain (non-deformed, as-drawn or galvanized), or deformed. Welded wire reinforcement is made from plain or deformed wire, or a combination of plain and deformed wire. Common wire sizes and dimensions are given in Table 1, Table 2, Table 3, and Table 4. Actual wire sizes are not restricted to those shown in the tables.

^A Table 1 should be used on projects that are designed using inch-pound units; Table 2 should be used on projects that are designed using SI units.

^B The number following the prefix indicates the nominal cross-sectional area of the wire in square inches multiplied by 100.

^C For sizes other than those shown above, the Size Number shall be the number of one hundredth of a square inch in the nominal area of the wire cross section, prefixed by the W.

^D These sizes represent the most readily available sizes in the welding wire reinforcement industry. Other wire sizes are available and many manufactures can produce them in 0.0015 in.² increments.

^E The nominal diameter is based on the nominal area of the wire.
