Patent abstract
A blow-molded unitary structure includes a panel having first and second panel walls and a generally hollow interior between the first and second panel walls. The structure also includes one or more different types of strengthening elements monolithically formed with the panel and across a substantial portion of the panel to enhance the strength of the structure. A strengthening element can be a depression recessing from the second panel wall toward an interior of the panel, a protrusion protruding from the second panel wall toward an exterior of the panel, a rib protruding outwardly toward the exterior of the panel and a trench formed by side walls of adjacent protrusions.
