The SuperPerf Pizza Screens produce a more evenly baked pizza, especially with as many holes have been placed on the SuperPerf Screen Disc. Due to the amount of holes on the Screen Disc, air flow is able to penetrate the pizza crust. The edges and holes on the SuperPerf Screen Discs are unfinished and may be sharp. The Screen Discs are made of 18 gauge aluminum with 3/8" holes. Another feature of the SuperPerf Screen Disc is that they are a better alternative to the standard pizza screen because of durability and longevity.
