Full-size aluminum sheet pan

The Chicago Metallic 40808 is a full-size sheet pan made from 18-gauge aluminum with a glazed finish. Its closed-bead rim adds rigidity and resists warping during heating. The pan measures 25 13/16 by 17 7/8 inches with a depth of 1 inch. It is oven safe and suited for high-volume baking or roasting.

Upgrade from thinner or warped trays

This pan replaces lightweight trays that buckle under heat or repeated use. The heavier gauge and closed bead hold flat across the entire surface, so cookies, sheet cakes, and roasted vegetables cook evenly. The jump is worth it when your current pans show permanent bends, dark spots, or uneven browning that cannot be corrected by rotation.

Check oven clearance and cleaning needs

Verify that your oven interior can accommodate a tray 25 13/16 inches long and 17 7/8 inches wide with at least 1 inch of vertical space. The glazed aluminum surface is not dishwasher safe and must be washed by hand. It is not rated for freezer use, so plan separate containers for cold storage. Buyers who need a non-stick coating or a perforated surface for air circulation should look elsewhere.

Questions about this item

Will the 25 13/16 x 17 7/8 in sheet pan fit my standard oven rack?

The pan measures 25 13/16 inches long by 17 7/8 inches wide, so compare those dimensions to your oven rack clearance before buying.

How should I clean the glazed aluminum pan after the first use to protect the coating?

Hand-wash only with mild detergent and a non-abrasive sponge; the manufacturer states the pan is not dishwasher safe.

When will the 18-gauge aluminum start to warp and need replacement?

The Stayflat design and closed-bead rim resist warping under normal oven temperatures; replace only if the pan no longer sits flat or the glaze chips.
