This line of Non-Stick Pro Bakeware is made of heavy-grade aluminized steel that ensures durability and promotes even heat distribution for a more reliable bake and is coated with a commercial grade, double-layer, ceramic-reinforced PTFE non-stick coating. This provides powerful non-stick capability, as well as scratch-,stain-,corrosion-, and abrasion resistance. The non-stick line also features a micro-textured pattern that ensures even baking by minimizing your food's surface contact with the pan and promoting airflow
