Quarter-size Aluminium Baking Pan: Quarter-size Wear-Ever® heavy-duty aluminum sheet pan with natural finish: Built from heavy-duty aluminum, the Vollrath® Wear-Ever sheet pan is proven to be 20 percent stronger than the competition. It heats up and cools down quickly, and the pan’s concave bottom flattens for even heating. The natural finish ensures uniform results, and the tapered sides allow for convenient stacking.
