Professional pastry chefs and bakeries bake on aluminum sheets for perfect results. You can too, with our commercial quality Naturals® Bakeware collection. Made of pure aluminum, these premium pans produce evenly browned baked goods every time. Rims are reinforced with galvanized steel to prevent warping and aluminum will never rust. This standard jelly roll pan is slightly smaller than our half sheet. Fits European sized ovens. For baked veggies, French fries, muffins, cookies, cakes and more.
