Are these the heavy duty sheet pans everyone recommends (non-warping)?

I have both the Chicago Metallic and Lincoln Food Service sheet pans. Both perform well. Just be aware that there are two different gauges of metal for Lincoln Food Service sheet pans, so some pans are thinner than others. The restaurant supply store should be able to point you in the right direction, but when ordering online you may not know which you are getting. You can find mixed reviews on the Lincoln Food Service sheets online even though Cook's Illustrated gave them a big thumbs up, but it is my guess that a lot of people are getting the thinner sheets online and they are warping at really high temperatures.
