Claim:
1. A shelf supporting beam configuration for a shelving apparatus which comprises a plurality of vertically extending posts, comprising: a shelf platform having a base panel and a surrounding edge defining a cavity within said surrounding edge and said base panel; a plurality of shelf retaining members for detachably coupling with two of said posts to form a boundary frame to support said shelf platform therewithin, wherein each of said shelf retaining member has two coupling ends for detachably coupling with two of said posts in said unfolded condition, and first and second longitudinal edges extended between said two coupling ends, wherein each of said shelf retaining members provides a supporting surface extended from an inner side thereof between said two longitudinal edges to support said respective shelf platform and at least one longitudinal edge portion of each of said shelf retaining members is inwardly folded on an inner side thereof to form said longitudinal edge to reinforce a planar configuration of said retaining member, wherein each of said shelf retaining members has a plurality of supporting tabs horizontally aligned with each other and protruded from said inner side of each of said shelf retaining members between first and second longitudinal edges thereof and defines a plurality of discrete supporting surfaces on said supporting tabs to support said shelf platform thereon, wherein each of said supporting tabs has a triangular shape defining a peak pointing toward said second longitudinal edge of said shelf retaining member and a flat surface as said supporting surface facing toward said first longitudinal edge of said shelf retaining member, wherein said discrete supporting surfaces are aligned with each other at a same planar direction to form a flat support for supporting said shelf platform; a shelf supporting arrangement integrally extended from each of said shelf retaining members between said first and second longitudinal edges to support said shelf platform within said boundary frame, wherein said shelf platform is able to be selectively supported by said shelf supporting arrangement with said surrounding edge located below base panel and said cavity facing downward or said surrounding edge located above said base panel and said cavity facing upward.
