Bonjour Commercial Nonstick Bakeware is constructed of heavy gauge aluminized steel in the classic commercial style. Folded corner construction and reinforced rims provide added strength and resistance to warping or bending. This extremely durable commercial nonstick bakeware will provide spectacular results time and time again. Our professional two coat non-stick system withstands over 100,000 cycles of abrasion testing. The two tone coating on each piece of Bonjour bakeware has a darker interior for perfect release and a lighter exterior for more even baking. A commonly requested size in recipes for yeast breads, quick breads, and pound cakes, this 9"x5" loaf pan is also standard to many meat loaf recipes. Dishwasher safe with a limited lifetime warranty.
