Abstract
A reinforcement mat for reinforced concrete consists of longitudinal wires and crosswires which are welded together at their points of cross. End portions of the crosswires project out beyond the edge longitudinal wires and are bent back in the plane of the mat towards the edge longitudinal wires. The longitudinal wires are arranged symmetrically about the longitudinal centerline of the mat partly at wider and partly at narrower pitch. At each edge of the mat a family of at least two longitudinal wires are provided at the narrower pitch.
