Summary:Hitherto known gratings for covering shafts, channels or similar structures comprise peripheral rails cross-bars that are joined to the peripheral rails and consist of sheet metal sections, and longitudinal bars joined to the cross-bars. In order to provide a better foothold and improved anti-skid properties, the longitudinal bars are secured to the cross-bars in such a way that top stepping surfaces of the longitudinal bars are lower than or flush with at least stepping portions of upper edges of the cross-bars.
