The Prime Bakers and Moulders 16x12 Inch Aluminium Baking Tray is a large, versatile, and durable baking and roasting pan designed for both extensive home baking and light commercial use. This tray measures 16 inches in length and 12 inches in width. The depth can vary slightly, but it's typically around 2.5 to 3 inches, making it a deep tray suitable for substantial batches. For example, some listings specify it as 16x12x3 inches. Given its larger size, it's crucial to measure your oven's internal cavity (including rack placement) to ensure a proper fit. Some product descriptions mention outer dimensions, including the curved edges, might be around 17 inches by 13 inches.  It is expertly crafted from heavy-duty, food-grade aluminium sheet. Aluminium is an industry-standard for bakeware due to its exceptional thermal conductivity. This property ensures rapid and uniform heat distribution across the entire surface of the tray, which is vital for consistent baking and roasting, preventing cold spots or overcooked edges.
