Abstract
Plastic blow molded board-like members include a plurality of longitudinally extending, laterally spaced aligned channels/grooves in opposite sides of the members. Each of the channels has closely spaced apart side walls and inner end walls. The inner end walls of aligned channels in opposite sides of the member are joined together to provide a relatively high strength reinforced core. The ends of the members are completely closed during the blow molding process for increased strength and to keep out dirt and moisture.
