The only thing better than one sheet pan---is TWO, never be without the right size pan again! This set of two USA Pan Half Sheet and Quarter Sheet Pans are made in the USA from globally sourced material by a family owned and operated business. USA Pan baking pans are uniquely designed with a fluted corrugated surface which facilitates air circulation for even baking and also maximizes pan strength and reduces warping. 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. 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. Every USA Pan baking sheet pan is made in the USA and features a steel wire in the rim, which provides extra strength and further resistance to warping. Our baking sheet pan’s surface are 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. Hand wash 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.
