Components of and method for making a tube and fitting framework having panel recesses accepting structural panels in a plane tangent to the tubes. The tubes and fittings allow easy assembly of large structures. The panels secured within the panel recesses bear loads imposed on the structure and minimize torque at the fittings. The finished structure is streamlined, with flush junctions of all components. Alternative embodiments include panel recesses in angular or channeled shapes which act to secure the panels to the framework, and other panel securing devices which are externally invisible on the completed structure. Panel securing devices include screws, bolts, studs, pins, adhesives, welding and equivalents. Fittings are secured to tubes by connectors which may engage the interior of the tube in known ways, or by use of O-rings or rubber flanges. Tubes, fittings and panels may be made of any of a wide range of materials including metals, alloys, plastics, rubbers, wood, and composites. The panel recesses may engage the entire periphery of the panels, by traversing from tube to fitting around the entire periphery of the panel.

1. A structural kit comprising:a) at least one tube having a longitudinal axis and exterior and interior surfaces, the exterior surface of said tube having a circular cross-sectional configuration, the tube further having first and second tube ends, the tube having a first recess extending lengthwise from the first tube end to the second tube end along the exterior surface of the tube and parallel to the longitudinal axis of the tube, the first recess having a bottom wall and an intersecting peripheral wall, the first recess comprising a partial chordal section of the tube; b) at least one fitting having first and second coupling faces, the first coupling face being symmetrical to the first tube end; c) means for coupling the fitting to the tube with the first coupling face abutting and aligned with the first tube end; d) a panel having interior and exterior surfaces, the panel further having a panel edge which matches the outline and cross section of the first recess, the panel edge has a thickness defined by the exterior and interior surfaces of the panel; e) means for securing the panel edge within the first recess; and f) the thickness of the panel edge equals the dimension between the bottom wall of the first recess and the edge of the exterior surface of the tube at the peripheral wall so that when the panel edge is secured within the first recess the exterior surface of the panel is even with and tangential to the exterior surface of the tube.
