Abstract

It is known to form one or more faucet mounting holes in the deck portion of a metal sink. To separate the sink deck from the underlying countertop, a gasket is inserted between the sink and countertop in alignment with the holes. This method of construction sometimes results in a skink of inadequate strength to resist bending or warping of the deck around the holes when a faucet is secured on the deck, In addition, such holes often have sharp edges, which may cut through the brass supply tubes of a faucet. The present invention provides an integral deck support around each hole through the sink deck and a method for making the same, in which a deck support is formed by punching a hole in the deck of generally circular shape but such as to leave a plurality of projections extending a predetermined distance toward the center of the hole, extruding the material surrounding said hole downwardly so that the projections extend downwardly from the deck, and rolling said projections back from the hole to form feet spaced around the hole. This results in a sink deck of improved strength and rigidity, without sharp edges around the holes, and that does not require gaskets that may slip or be of improper thickness to separate the sink from the countertop.
