Longitudinally and transversely running, upended webs are connected to one another and to tread strips, located on the upper side, to form panels. Clamps integrally formed on the panel borders engage beneath the border of the respectively neighbouring panels. The web edges resting on the floor are provided with cutouts which make it possible to lay pipelines and electric cables beneath the grating. Between the tread strips, covering strips may be provided in one embodiment, with the result that a continuous surface is achieved. Conductive plastic makes earthing possible. <IMAGE>
