Blow-molded plastic structures are provided for use in various structures such as, but not limited to, tables, chairs, walls, backboards, storage bins, sports equipment and the like. The blow-molded plastic structure has a first surface and a second surface extending between a first end and a second end and forming a chamber there between. A plurality of depressions is formed on the second surface and extends into the chamber. The depressions are usually unitary structures formed by a depression wall. Generally, the steeper the depression wall, the more strength is provided to the structure. In addition, where the plurality of depressions has a low profile and a greater density, increased strength is provided to the structure. The depressions may or may not be joined to the first surface.
