Abstract
Abstract A deck assembly is described whereby each of at least two substantially identical modules include a panel, said panel having a portion thereof defining a groove adjacent to one edge of the panel; a plurality of ribs depending from the panel, one of the ribs carrying a flange having a locking notch or groove; a tongue extending along another edge or end of the panel, a lip extension extending outward from the portion of the panel defining the groove. The two modules may be interlocked together with a sealing strip interposed between the lip extension and the panel to provide a unitary platform, roof or cover.
