The USA Pan Extra Large or ¾ baking sheet pan lets you maximize your baking with a generous surface area, so you can whip up large batches of homemade cookies, roast veggies for a crowd or make the most of one sheet pan dinners. Our baking sheet pans feature a unique corrugated surface which provides air circulation all around for better browning, more even baking and super easy release. The extra large cookie sheets surface is finished with USA Pan’s proprietary AMERICOAT nonstick coating, a nonstick silicone - which allows easy release of baked goods from the pan and makes clean up a breeze. USA Pan bakeware is made with aluminized steel, the material of choice for commercial bakeries. Steel for maximum strength and long term durability and aluminum for superior heat conductivity. Our sheet pans are finished with a steel wire in the rim, which provides extra strength and further resistance to warping. Do not exceed 450°F (230°C). Please note, our bakeware conducts heat efficiently, which may require you to reduce the time and temperature as necessary. Hand wash nonstick bakeware in warm water with mild dishwashing soap using a sponge, rinse and dry thoroughly. Do not place in dishwasher. We recommend using only silicone, nylon or wooden utensils. Do not use sharp metal utensils. Proudly made in the USA from globally sourced materials. USA Pan is a Bundy Family owned company, based in the Greater Pittsburgh, Pennsylvania area that has been producing high performance bakeware for over 60 years. Baking Surface Dimensions: 20.25 x 14.25 x 1 inches; Outer Dimensions 20.75 x 14.75 x 1 inches.
