Interlocking cover members made of a rigid polyvinyl chloride (PVC) material and formed by an extrusion process are each defined by a main panel having a top side with a top surface, a bottom side, and opposite first and second longitudinal edge zones. Longitudinal rib members extend downwardly from the bottom side of the panel in spaced, parallel relation to one another to strengthen and stabilize the panel in supported, spaced relation above an underlying surface being covered. An attachment lip extends outboard of the second longitudinal edge zone, below a level of the panel, and includes a lock channel for interlocking receipt of a barbed rail extending from the bottom side of an adjacently positioned cover member. The attachment lip is structured to rest on the surface being covered and accommodates screw fasteners, at spaced intervals, for securing the cover member to the underlying surface. The first longitudinal edge zone of the adjacently positioned cover member extends over the attachment lip to conceal the screw fasteners, thereby providing a finished aesthetically appealing appearance to the deck surface.
