Abstract

In apertured panels comprising a plurality of wires (10) having loops (12) at intervals along their lengths and spaced so as to define slit apertures (13) between adjacent wires, the wires being connected together as a panel by tie rods, tubes or the like (11) extending through aligned loops thereof, loop parts of at least some of the wires are secured to a rib member or members extending transversely thereof. The rib member(s) may cooperate seatingly with the loops over at least part of the length of the rib member(s). The rib is preferably a hollow member, for example an inverted V-section channel. Such an arrangement is intended to overcome problems of aligning the rib to the loop in manufacture and also of distortion, specifically bowing, of the rib or/and underlying tie rod.
