ABSTRACT:
A post for use in, for example, street-lighting, comprising a number of substantially longitudinal stiffening rods of a suitable material, such as steel, fastened to an interior or exterior shell of a suitable material, such as steel. The novel matter of the invention is that the connections which give the different parts of the pole their static cooperation, are broken at a certain measure of transverse stress caused by, for example, collision with a motor vehicle, so that the pole's strength and resistance to deformation are greatly reduced.
