Torsion box construction is ideal when a flat, stable and amazingly strong surface is required. Long shelves with wide spread supports, cabinets with long spread legs or tables with extended cantilevered tops can all be made with torsion box construction. Airplane wings and boat hulls are often made with this technique, too. Torsion boxes for furniture can be made with readily available materials. Composites, like MDF, applied over softwood ribs are the most common. Special paper products that look like honeycomb have been designed specifically for the interior of these boxes. The exterior surface can be veneered or even painted. They are surprisingly simple to make and very low tech, but at the same time, offer an innovative structural solution for many design challenges, whether it’s a flat top or a load bearing vertical support.
