Abstract: Shelving to hold pizza cartons which is made up of various elements (A), for holding of the cartons (S), set alongside each other, or of a single element (B), containing a multiple stecking stacking zone, where these elements present on all sides, apart from the frontal zone, on the bottom and on the cover, protection walls (1,2,3,4) and carton (S) containment, while the frontal zone presents L-shaped profilings (6) and/or T-shaped profilings (12) for cartons (S) containment, where the profiles (6, 12) show include cuts (7) in the lower part and/or recesses (17) in the central zone, useful for the extraction of the cartons from below below and/or from the centre center of the shelf. The shelving also includes eventually presents a cupboard (27) for the containment of the packs of flat punched cartons useful for the preparation of the cartons by the user and presents a suitable table for preparing the cartons and for introducing the pizza in the cartons (S).
