Abstract
An elongated sheet of stainless steel material includes alternately spaced apart laterally extending slots and ridges formed by removing a length of material and then applying downward pressure within the slots to form downwardly extending rounded slot edges. Upward pressure is applied along a line between the slots to form rounded ridges having oppositely extending downwardly sloping surfaces which merge into flat surfaces extending to the adjacent slot edges. The opposite sides of the floor members include downwardly extending side walls which slope inwardly towards each other such that side walls of adjacent floor members form elongated openings which increase in width downwardly. An A-shaped strengthening member may be provided under the floor member along its center line and supported by vertically disposed end channels the upper legs of which have downwardly extending return bend portions providing rounded edges therealong.
