ABSTRACT:
A plank for loading surfaces of a picnic bench, bleacher, boat dock and the like including an elongated element formed of a synthetic resin, a plurality of elongated reinforcing bars, and structure provided for connecting the reinforcing bars to the synthetic resin element. The synthetic resin element is formed with a substantially flat web defining a load surface and an undersurface, a pair of side walls extending normally from the undersurface along the length of the element, a plurality of internal walls inward of and parallel to the side walls, and structure for restraining twisting of the reinforcing bars about their longitudinal axis during loading of the plank. The reinforcing bars support the synthetic resin element and restrict bending along the length of the element.
