Abstract
An all plastic shelf is part of a shelving system and is provided for uses where metal shelves might rust or corrode, especially if attacked by hostile chemicals. The underside of the plastic shelf has a channel formed around the periphery thereof. A welded metal frame fits into the channel, with either the width of the frame or a cover plate substantially covering the channel in order to prevent an entry of foreign matter therein. Sockets are formed in the corners of the frame to receive corner posts for supporting the shelf. These sockets fit into corner sockets which are molded into the metal frame.
