You just cant beat Nordic Ware sheet pans. They are high quality, do not flex or bend in the oven and as long as you dont put them in the dishwasher they will retain their finish. I dont ever directly roast most things on them, I always use non stick foil so I dont risk burning food getting stuck to them. Ive had a set for 10 years and they are still great sheet pans with no rust. I bought these because they were on sale and it would bring me up to 4 pans so I can get rid of all my cheap cookie sheets. I highly recommend these!
