A bar element as a construction element includes strips preferably produced from bamboo and is hollow at least in certain regions. The hollow interior is formed at least in certain sections as a hollow fillet achieved by a plastic and/or resin introduced into the bar elements, using a shaped body movable through the interior. Producing bar elements from interconnected strips ensures that although produced from a natural raw material, the bar elements have a reproducible outer cross section. Using a shaped body movable through the interior to produce the inner cross section also ensures a defined inner cross section of the bar elements, with the result that in turn connections between a plurality of bar elements that are defined by suitable connection elements can be formed. In this way, the bar elements make it possible to produce lattice works, grid constructions, frameworks or other desired structures and/or three-dimensional bodies.
