Shelf for supporting articles, particularly in refrigerated installations

A method of manufacturing a shelf including a panel and a continuous plastic structure which fixedly surrounds the entire periphery and all edges of said panel, comprising forming the continuous plastic structure separately from the panel by hot molding in a mold, assembling the panel with the continuous plastic structure such that the continuous plastic structure completely surrounds the entire periphery and all edges of the panel outside of the mold before the continuous plastic structure has fully shrunk, and cooling the continuous plastic structure to thereby cause shrinking of the continuous plastic structure around the entire periphery of the panel and the mating of the continuous plastic structure to the panel around the entire periphery and all edges of the panel,

• wherein the panel is held in place by clipping between tabs or tongues or lugs provided on said continuous plastic structure and the remainder of said structure, said panel being forcibly inserted between said tabs or tongues or lugs and said remainder of said structure before the continuous plastic structure has fully shrunk, and
• wherein an elastic adhesive is deposited on at least part of the continuous plastic structure that is to be in contact with the panel prior to the panel being forcibly inserted between said tabs or tongues or lugs and said remainder of said structure and before the continuous plastic structure has fully shrunk.
