Standard Specification for Welded Deformed Steel Bar Mats for Concrete Reinforcement
|Publication Date:||1 January 2007|
This specification covers material in mat (or sheet) form fabricated from deformed steel bars to be used for the reinforcement of concrete. Mats consist of two layers of bars that are assembled at right angles to each other. Mats shall be assembled by welding at the intersections.
This specification is applicable to orders in either SI units (M 54M) or inch-pound units (M 54).
The values stated in either inch-pound units 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 from the two systems may result in nonconformance with this specification.
