1.1 This specification covers material in mat (or sheet) form fabricated from hot-rolled, plain steel bars or rods to be used for the reinforcement of concrete. Mats consist of two layers of bars or rods which are assembled by welding at right angles to each other.
1.2 This specification is applicable for orders in either inch-pound units (as A 704) or in SI units [as A 704M].
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.
