Why a Heavy Sheet Pan Is Worth the Weight
Thin sheet pans heat quickly, but they also change shape quickly as different parts of the metal expand at different rates. That familiar loud pop in the oven is the pan flexing as it heats. Heavier-gauge pans resist that distortion better and tend to distribute heat more evenly.
