An inflated tube for use as a structual element has the distinction of using spiralling, high strength ribbons mounted on a fabric skin containing a bladder. Ribbons are also mounted on the outside of the skin parallel to the axis of the tube to reinforce the tube against bending forces. The use of ribbons provides a less expensive structural element than that made of woven fibers. The application is for only moderate loads and moderate spans compared to the those made of woven fibers.
