Shelf Supporting Beam Configuration for Shelving Apparatus

Abstract

A shelf supporting beam configuration for a shelving apparatus, includes a shelf platform, a plurality of shelf retaining members, and shelf supporting arrangement. Each shelf retaining member has two coupling ends for detachably coupling with two vertically extending posts of the shelving apparatus, and first and second longitudinal edges extended between the two coupling ends to form a boundary frame. The shelf supporting arrangement is integrally extended from each of the shelf retaining members between the first and second longitudinal edges to rigidly support the shelf platform within the boundary frame.
