Abstract (en)
[origin: WO8403319A1] Construction elements of predetermined cross-sectional profiles are formed of wood, plastic and/or metal. These construction elements are useful in building construction, preformed panel systems and preformed truss structures. The shapes of the construction elements are also adaptable to a toy construction set.
