I am doing a lot of research on torsion boxes and the qualities associated with building with them. I am very interested in building a solid workbench to start out with. If all goes well, I would like to start building tables and doors using the same torsion box method.

Upon actually trying to put together a good torsion box panel in my workshop, I found that building one of these things is going to be much more labor intensive than I had originally hoped.

Does anyone know of a company that manufactures torsion boxes/torsion box panels that I could use as a raw material for these projects?

Thanks.
