This cookie sheet pan set uses extra-thick carbon steel to provide durability and stable heat distribution. A diamond texture on the base enhances nonstick performance and promotes even heat airflow for consistent baking. The set includes three nonstick pans in sizes 13x9 inches, 15x10 inches, and 17.5x12 inches, covering cookies, pastries, lasagna, jelly rolls, and roasted meats. The pans are designed to resist warping and maintain shape through repeated use, with a heat tolerance up to 450 degrees Fahrenheit. The nonstick coating is a two-layer finish that is free of PFOA, BPA and PTFE, offering reliable release and easier cleanup. The surface resists scratching and staining, contributing to long-term upkeep. The finish is practical for daily kitchen tasks and can complement a range of table settings with a simple, neutral appearance. This set supports versatile meal preparation and consistent results across different recipes and batch sizes, making it a convenient option for home baking and roasting. The base design helps airflow around baked goods, promoting even browning on both sheet pans and roasters. Designed for routine use, these pans tolerate frequent oven cycles without obvious warping. Color: Gold.
