An extrusion is provided that may be used in the construction of a framework assembly and that is lighter, stronger and less expensive than previously available extrusions. In various aspects, the extrusion generally has four sides and is quadrangular in cross-section. A web member may extend the inside of the cross-section of the extrusion between two of the sides. The web member thus may bisect the interior of extrusion forming a first interior cavity and a second interior cavity. The first and second cavities may be equally dimensioned in cross-section. The extrusion may be a metal extrusion formed from aluminum and/or steel.
