Commercial grade bakeware for the home baker will allow you to create professional results in your own kitchen. Cookie sheet pans are made of Aluminized Steel and coated with a non stick silicone coating, so baked goods will not stick to the pan. Warp resistant, heavy-duty and reliable bakeware means your baked goods will turn out the same every time. The fluted surface on the bottom of the pan adds strength and facilitates even baking and heat distribution. The raised lip makes these pans ideal for brownies, cookies, sheet cakes and roasting.
