ABSTRACT:
A welded wire lathing material for mounting stucco plaster and the like onto a building frame. This lathing material comprises intersecting transverse and primary longitudinal strands substantially located in a first plane. It also comprises secondary longitudinal strands also substantially placed in first plane and closely spaced with, some of primary longitudinal strands, thus forming longitudinal slots located at predetermined spaced intervals extending across the lathing material. The slots are wider than the shaft, but narrower than the head, of fasteners predetermined for attaching the lath to building frames. The longitudinal and transverse strands are welded together where they intersect to form a rectangular mesh approximately located in the first plane. In addition, spacing furrs are formed in the mesh by bending the transverse strands into indentations perpendicular to, and on one side of, the first plane, at predetermined space intervals and located away from points of intersection with the longitudinal strands such that the tip of the indentations defines a second plane away from the first plane. This furring structure allows the lathing material to be kept mostly separated from a building frame when it is placed with the indentations against the building frame. This structure together with shaping and flattening of the longitudinal strands allows the lath to be easily packaged into rolls.
