The Chicago Metallic 30694 1/1 Full Size Bun/Sheet Pan is a workhorse for commercial kitchens, combining durability with performance. Crafted from 16-gauge aluminum, this 26" x 18" x 1" sheet pan is designed for rigorous use while maintaining lightweight ease. Its StayFlat® technology ensures it resists denting and bowing, providing a flat surface even under repeated high-heat conditions—critical for even baking of cookies, rolls, and potatoes. The band-in rim reinforces sidewalls, reducing flare risks and extending longevity, making it a cost-effective choice for high-volume bakeries and restaurants. Whether you're baking sheet cakes, cookies, or roasting vegetables, this pan delivers consistent results without warping, saving time and reducing waste. Its slightly concaved bottom flattens when heated, promoting uniform heat distribution for perfect baking every time.
