Abstract
An improved anti-skid tread or grating (10) design is provided with gripping members or rosettes (30) having a plurality of upstanding individual lobes (36) which are configured in such a way and project high enough to provide an excellent gripping surface. The lobes (36) of the design are self-cleaning, and have non-continuous gripping edges at their crests (40) that accommodate a greater build up of ice or mud without clogging the grating (10).
