Abstract

A pizza supporting and baking grid structure or pizza grill is disclosed as including a self-supporting metal screen having opposed faces and an outer periphery. The metal screen preferably has an open-mesh expanded metal construction. A circumferentially continuous one-piece rim extends about the outer periphery of the screen including opposed faces of the screen which are proximate to the outer periphery thereof. The rim has a generally flat annular rim section and an integral generally upstanding rim section which is re-shaped following assembly and juxtaposition of the screen relative to the generally flat annular rim section. The re-shaping of the integral generally upstanding rim section causes it to be moved into generally opposed and parallel relationship relative to the generally flat annular rim section so as to capture the screen therebetween. In this way, a circumferentially strengthened rim with an easy-to-clean and circumferentially continuous outer rim surfaces surrounding the screen is provided.
