Abstract
An elevated floor panel is disclosed formed of a sheet metal upper surface member and a sheet metal lower support member. The lower support member is provided with a plurality of apertures arranged in perpendicular rows across the panel. Integral legs formed of material displaced from the apertures are symmetrically arranged around each aperture and extend laterally to the upper surface member. Each leg is provided with a foot portion welded to the under surface of the surface member. The edges of the lower support member are bent laterally to provide sidewalls extending to the upper surface member and terminating in flanges welded to the upper surface member. The panel structure permits the panel to be supported at its corners and to sustain substantial loads with small load-induced deflections.
