A rotary slitting blade for fabricating expanded metal products includes opposed end surfaces and an outer circumferential surface extending from one of the end surfaces to the other of the end surfaces. A plurality of notches are formed in each of the end surfaces. The notches include curved surfaces having convex curvatures that smoothly transition into one of the end surfaces and/or the outer circumferential surface. The rotary slitting blade improves the quality of a resulting expanded metal product by reducing or eliminating tears, cracks, and fractures in the expanded metal product.

A stud such as a light-weight metal stud can include a first elongated channel member and a second elongated channel member coupled to the first elongated channel member by a wire matrix, where ends of the wire matrix are located at ends of the first and second channel members. A pitch of the wire matrix can vary over the length of the stud. Two or more such studs can have different lengths where a difference in the lengths is not a multiple of the pitch.

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.

The invention relates to metal wire mesh having a plurality of longitudinal wires and a plurality of transverse wires. The longitudinal wires of the mesh are provided with shaped areas wherein the moment of inertia of said shaped areas about the neutral axis parallel to the plane of the mesh is 90 percent or less of the moment of inertia of said shaped areas about the neutral axis vertical to the plane of the mesh. This substantially reduces the problem of curvature set when metal wire mesh is rolled for packaging or transport and attempts are made to unroll prior to use.
