ABSTRACT:
The invention is concerned with a shelving structure of the kind which is assembled from a number of vertical elements (struts) and interconnected horizontal elements (beams), and in particular to a shelf for such a shelving structure. Such shelves are conventionally formed from sheet metal, comprising a horizontal shelf panel and flanges extending vertically downwardly from the shelf panel on at least two sides thereof, each flange being folded backwardly on itself to increase the strength of the flange. In accordance with this invention, each flange is so folded as to provide a pocket in which an elongate reinforcing member is positioned, such reinforcing members engaging the underside of the shelf panel. In particular, each flange comprises a first portion extending downwardly from the panel, a second portion folded inwardly so as to extend towards the underside of the shelf panel generally parallel to, and spaced from the first portion, the reinforcing member being located between said first and second portions, transmitting load from the shelf by virtue of its engagement with the underside of the shelf and transmitting such load to an intermediate portion between said first and second portions.
