    Patent number: 6427395
    Abstract: An elongated member suitable for flooring, decking, or seating, having a top plate formed as an extrusion of plastic material, wherein the top plate includes ribs constituted by protruding parts of parallel, spaced, elongated friction elements co-extruded therewith, the friction elements being formed of plastic having distinctly greater softness or flexibility than the main parts of the top plate and suitable for providing a non-slip surface. The member may include an elongated support formed as a relatively rigid extrusion of plastic material having a base plate with upstanding side walls and a central support portion, the top plate overlying the support and having edge formations engaging the side walls. Alternatively, the top plate and support may be formed integrally by extrusion, or the top plate may be part of a plank cover having integrally formed ribs for spacing the top plate above a plank.
