Summary:Hitherto known gratings for covering shafts, channels or similar structures comprise peripheral rails (10, 10′) cross-bars (20) that are joined to the peripheral rails (10, 10′) and consist of sheet metal sections, and longitudinal bars (30) joined to the cross-bars (20). In order to provide a better foothold and improved anti-skid properties, the longitudinal bars (30) are secured to the cross-bars (20) in such a way that top stepping surfaces (31) of the longitudinal bars (30) are lower than or flush with at least stepping portions (21) of upper edges (22) of the cross-bars (20).
