Provided is a load-carrying or non-load carrying structural component for a vehicle having improved impact resistance, such as a gas tank protection shield, an underbody shield, a structural panel, an interior floor, a floor pan, a roof, an exterior surface, a storage area, a glove box, a console box, a trunk, a trunk floor, a truck bed, and combinations thereof. The component has a support structure with ridges, each spaced apart from one another at predetermined intervals, to form a corrugated surface capable of load-carrying. The ridges are longitudinally extending, raised ridges and define top and side walls. A plurality of strategically thickened areas is on at least one of the top wall and side walls.
