<p>A molded plastic panel and assembly including at least two molded panels are described. Each panel includes a center portion that is positioned between a first external portion and a second external portion. The center portion has reinforcing structures that define a plurality of center portion apertures. Each of the external portions includes reinforcing structures having sidewalls that define a plurality of external portion apertures. The exterior surfaces of sidewalls of neighboring reinforcing structures define external portion recesses that receive extensions from a separate article, thereby forming interlocks. With the panel assembly of the present invention, molded panels are positioned such that a portion of each panel overlaps with a portion of the other panel, and some of the center reinforcing structures are received within at least some of the external portion recesses aligned therewith, and together form interlocks that attach the panels together.</p> |
