USA PAN Aluminized Steel Lasagna Pan, 13 3/4 x 10 3/8 x 3 Inch. Each USA Pan is constructed of aluminized steel, the material of choice for commercial bakeries. Metal thicknesses have been selected that allow even heat distribution and maximum service life. Steel wires in the rim construction of most pans to provide additional strength and resist warping. Each pan is coated with AMERICOATÂ© Plus, a proprietary silicone coating that nearly all North American bakers prefer over dark non-stick coatings. AMERICOATÂ© Plus is a clear non-stick, environmentally friendly coating that is specifically formulated for superior baking and does not contain any PTFEâs or PFOAâs. Another unique feature of USA Pan bakeware is the corrugated, or fluted, design. The corrugation maximizes pan strength and prevents warping, denting and other effects of everyday use. Corrugation also minimizes surface contact with baked goods which translates into an evenly baked product that is easily released.
