Abstract
A pipe extrusion includes a cross-section with a substantially round outer perimeter. A round portion of the substantially round outer perimeter preferably has an included angle of less than 300 degrees. A pair of inward facing flanges terminate the round portion. A cross member is formed across an inner area of the round portion. The cross member is parallel with the pair of inward facing flanges. A position of the cross member relative to a centerline of the round portion is between 0-20 degrees from the center line of the round portion. The pipe extrusion is preferably fabricated from any suitable aluminum alloy, such as T-6 aluminum.
