ASTM A184/A184M-01

1.1 This specification covers material in mat (or sheet) form fabricated from hot-rolled deformed steel bars to be used for the reinforcement of concrete. The mats shall consist of two layers of bars that are assembled at right angles to each other. Mats may be assembled by clipping or welding at the intersections.

1.2 This specification is applicable for orders in either inch-pound units (as Specification A184) or SI units (as Specification A184M).

1.3 The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI 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 from the two systems may result in nonconformance with this specification.
