ABSTRACT:
A hollow structural member including a top wall having an inner surface and a substantially planar outer surface. A bottom wall opposes the top wall so as to define a void therebetween and has at least one bulwark formed therein. Each bulwark has a leading face which is joined to the inner surface of the top wall to form a double-walled bulwark bridging the void. The double-walled bulwark has opposing walls and a reinforcing member that is encapsulated thereby. A process for producing a hollow structural member includes placing a parison between two mold halves before bringing together the first and second mold halves. A movable blade is positioned therein. When in the closed position, movable blade is extended into a cavity defined by the first and second mold halves to form the bulwark in the second portion of the parison to be formed into a bottom wall.
