A pizza restaurant deck is a thick, hot floor. A steel is the closest thing that fits on an oven rack. The Original (about 14×16 inches, ¼ inch thick) is the one testers keep naming.
Preheat 45–60 minutes at the top of the oven. Launch. You will get a better New York or grandma pie than any stone at the same temperature. Heavy. Worth the floor space.
