good quality sheets

Great looking cookie sheets for many uses. Can fit in the dishwasher just fine. I use parchment paper and the cleanup is minimal and maybe no dishwasher is even necessary.

My impression of Calphalon Nonstick Bakeware 12x17-inch Baking Sheet Set, 2 Piece This is nice 2 pieces for backing anything flat and not really huge size. I like to bake meat, chicken, vegetables in my owen in this decos. Constructed with heavy-gauge steel cores, these sheets are designed to brown even the most delicate cookies evenly, making them hardworking kitchen tools for years to come. The interlocking nonstick layers deliver high performance release, minimizing broken cookies and stuck-on baked goods. It is easy to handwash or dish wash. Just be careful it’s easy to scratch with a knife of sharp fork. Set includes: (2) 12x17-inch baking sheets • 4.45 pounds assembled product weight •Nonstick surface releases food easily /but o notices it’s still stick so I’m using an aluminum foil on the bottom and completely cover food when baking the pork ribs for example/ • Raised sides prevent spills and drips • Heavy-gauge steel core heats evenly • Dishwasher safe for easy cleanup • Oven-safe to 500 degrees Fahrenheit. •Protected by a full lifetime warranty

Could be better

I like the pan, but whenever I get it from out of the dishwasher there's rust filled water coming out of the edges. You can also see discoloration already happening on the logo in the middle. Otherwise it's great quality. I use them with a silicone mat.

Pan warps

We got these from our wedding registry and rarely use them due to them warping in the oven. This product is reported to be safe up 450 degrees, however, I just used them again today and the pan warped within one minute of putting them in a 380 degree oven. Once the pans cool back down, they level back out, but I don’t want to risk my food being ruined or spilling all over my oven due to the pans warping. They feel thick and sturdy when holding them, but they are clearly made with cheap materials.
