Abstract

The present invention relates to a horizontal or slopped decking panel for use with a storage rack. The decking panel may include a plurality of laterally spaced parallel structural beams have first and second ends and a metal sheet. The metal sheet may extend around and under the first and second ends of the structural beams to define a first panel edge and a first bottom return sheet portion. The metal sheet may extend around and under the second ends of the structural beams to define a second panel edge and a second bottom return sheet portion. The metal sheet may have a plurality of top perforations. The first and second bottom return sheet portions may have first and second rows, respectively, of bottom perforations. Each of the bottom perforations may be aligned with one of the top perforations so that a post of a divider wall can be received.
