A longitudinally extending cellular body of a wood plastic composite is disclosed. The body has at least one wall which extends at least substantially the longitudinal length of the body, and encloses a central cavity which extends a distance that is less than the longitudinal length of said body. The cellular body has an impervious integral skin and has an exterior surface which is smooth to the touch. The surface has voids and has the appearance of wood. When the cellular body is struck, it makes a sound like the sound of a piece of wood being struck.
