Abstract

An artificial beam is formed from a sheet of substrate such as particle board which is covered on one side by a vinyl polymer such as polyvinyl chloride. The sheet is grooved longitudinally along the inner surface such that mitered edges at the hinge joints allow the formation of frontal, angled and side panels when the sheet is folded to become the beam structure.
