Abstract
Abstract A supporting base for a rack formed of four "c" channel members joined end to end defining a rectangular frame. The "c" channel members have an open side facing the center thereof into which the free edges of an expanded metal member corresponding in size to the frame extends and is secured to the bottom side of an upper flange thereof as by welding. Cross braces are carried below the expanded member and terminate within the "c" channel members with the expanded metal member being supported on an upper surface thereof. In one particular embodiment, the expanded metal member slopes towards an axis extending between opposed sides so that when articles are positioned thereon, such will also slope towards said axis.
