Abstract

Disclosed is a unitary, injection-molded raised flooring panel adapted for use in a raised flooring assembly. The raised flooring assembly includes a grid of flooring panel support stringers onto which the flooring panel is supported. The unitary, injection-molded raised flooring panel includes a continuous flooring wall the upper surface of which is the flooring surface of a panel and a plurality of depending, mutually intersecting reinforcing ribs formed integrally with the flooring wall of the panel. In the preferred embodiment, the flooring panel is made of a thermoplastic material, a thermosetting plastic material or a synthetic polymeric resin material. Thus, the disclosed flooring panel may be completely fabricated in a single manufacturing operation.
