I've heard many references to "Torsion Boxes" in this forum and other sources and have no clue as to what these are and for what purpose they are are used.

Torsion Box

A torsion box design is usually used to create a perfectly flat, rigid, strong and lightweight for its size table top, workbench or assembly table. The torsion box is an egg crate design inbetween 2 sheets of plywood or MDF.
Search this forum for more detailed descriptions and actual design configurations.
