Abstract
A shelf system comprising a shelf plate having a length defined by a longitudinal axis and a width defined by a latitudinal axis. A series of ribs are molded into the plate on its bottom face. These ribs are offset from the longitudinal axis and the latitudinal axis so that they intersect these axes at non-right angles, preferably forming diamond shaped patterns on the underside of the shelf plate. These diamond shaped patterns are designed to increase the strength of these shelves with a minimal amount of support material.
