Fabrication
“Strong, light, and darn good looking!”
The technological advances in tube construction in the last decade have been staggering. These advances have lead to lighter and stronger products for many industries, including aerospace, automotive and bicycle.
The ability to shape tubes allows the manufacturer to control the direction of the strength of the tube. A simple round tube is equally strong in every direction, while an ovalized tube is strongest in the direction that the tube has been lengthened.
The ability to vary the thickness of the tubes allows this forming process to be even more improved.
The Marvel Wheelchair frame uses ovalized tubes to support the axle, and a custom formed and extruded tube to support and join the seat and caster wing assembly. This construction process allows us to maximize the strength to weight ratio of our frame, and we are currently the only wheelchair manufacturer in the world using this technology.
