To withstand the most demanding kitchens, American Metalcraft has created Hard Coat Anodized Mega Pizza Screens. These pizza baking screens are made from hard coat aluminum, a metal that has gone through an electro-chemical process to create aluminum oxide, a hard, dark metal that will not flake off. It is the only screen that is NSF approved and its quality shows in its durability, ensuring a product that will last 5 to 10 times longer than standard pizzas screens. The screens are still highly perforated with open rims to allow optimal air flow, but are made from a solid piece of metal to hold up longer and guarantee a clean, safe product. For their quality, these screens are a great price and will benefit pizza kitchens in every establishment. This 18” Hard Coat Anodized Mega Pizza Screen (HC28718) has an outside diameter of 18.75 inches and an inside diameter of 18 inches, and is the largest available.
