After months (close to a year) of searching and trialing different baking sheets, I have found the perfect (or two perfect) ones for your consideration. I am hoping this to be a very informative review and I hope you will like it! I hope this is going to be helpful to you. Learn from my experience (and trial and error) so you buy the correct baking sheet the first time—save you time, money, and energy.This review is going to focus on two of my favorite brand’s QUARTER SHEET BAKING SHEETS. The results may or may not apply to HALF SHEETS or any other sizes. Why? Because a manufacturer may make their products differently for different product lines. Just like Ford may make good truck but not their sedans, or Subaru makes good SUVs but not necessarily pickups. It’s just an analogy! Anyway, Nordic and Vollrath are being compared here. I didn’t get the Chicago Metallic brand… maybe next time!!To start – I baked side-by-side using both brands and here are my findings:They are both “standard sized” quarter sheets – but one is slightly larger than the other. The Vollrath brand is slightly larger (or perhaps Nordic is slightly smaller??). Your “standard size” quarter-sheet baking rack will sit perfectly inside the Vollrath sheet flush and flat. On the other hand, the same rack will not sit flush in Nordic pan. In fact, you will have to very carefully balance the rack on the edge of the Nordic quarter-sheet … and if you but it just a little . .. . slush~ the rack will fall into the pan or fall off entirely.See the attached photos. So, is backing rack an important feature for your particular bake job? If yes, then you will have a hard time using the Nordic brand—either that or you have to buy purposefully smaller sized baking rack than what is “standard sized.” If not, who cares. I do need a baking rack for many of the things I bake—a rack that falls off easily is not acceptable to me. But who needs a rack for cookies? Wings? You have to think about this aspect for your own purposes.Manufacturing: the Nordic pan was perfect in attention to details. The photo of the back of the quarter-sheet pan shows you how each manufacturer rolled their heavy duty aluminum. Nordic rolled theirs much more perfectly and more detailed. See photo. On the other hand, Vollrath pan was kind of …Meh~ Like as if the manufacturer said “that’s good enough of a roll.” Does the bad rolling job make the Vollrath pan useless? No. The baking result is not impacted from my test-baking. But there’s something to be said about perfection.True Heavy Weight?: Both brands claim to be “Heavy Duty.” Check out the photos: Vollrath weighs in at 348 grams while the Nordic weighs in at 460 grams. If you do the math, this means the Nordic quarter sheet is approximately 30% more material! Yes, there’s 30% more aluminum in the Nordic quarter-sheet than the Vollrath product. That’s “30% heavier” duty.. I suppose you can put it that way. But the baking result with the Vollrath is not impacted (no warping, food bakes out equally on a side-by-side bake test). So is the extra 30% more material necessary? Thin baking sheet has the problem of bending and warping during baking (this is a known problem). If the product does NOT bend of warp… 348 gm vs. 460 gm ? Hmm. I dunno.But then again .. . Nordic is heavier weight, great, but it doesn’t accommodate a “standard sized” baking rack!!! Which is more important?? Now that’s where you need to decide for yourself.If you bake often foods that require a rack, you absolutely need a smaller rack or use the Vollrath quarter sheet to accommodate standard quarter-sheet racks. The Nordic will not fit those. On the other hand, if your bake often foods that sit directly on the pan and do not need a rack, or only uses the rack sporadically, you might be better off getting the Nordic quarter sheet and enjoy its 30% heavier weight and better machine job / better attention to details. Or get both – one Vollrath for one job, one Nordic for another job.OR, go find a smaller quarter-sheet rack (say, 1/8” smaller each side) to accommodate the Nordic quarter-sheet, then you have the best of both worlds. But that means you have to buy “less than standard sized” baking rack by about 1/8” smaller each side. Why can’t just “standard sized” things work standardly? Why don’t they just work perfectly? That was my frustration with Nordic quarter-sheet this entire time. I love that quarter-sheet but whenever I needed to use a rack, Nordic became useless to me.Thickness: You can see from the photos that the Nordic quarter-sheet is slightly thicker than the Vollrath. This came from being 30% more weight/material. I am not detecting the benefit of this extra thickness. Better heat retention? More anti-warping? More stable? Heavier? Stronger?Other things: Both quarter-sheets are NOT (I repeat, NOT) safe in dishwasher. They both need to be hand washed. They both do NOT come seasoned and they are NOT non-stick. Your best bet is put down a sheet of silicon baking sheet. I personally don’t recommend aluminum foil (but that’s what everyone does). My recommendation against aluminum foil is the excessive intake of aluminum which may be associated with Alzheimer’s disease. (This is not a medical preach, please use your own research). I simply recommend you use a silicon baking mat instead of an aluminum foil bottom to avoid getting even more aluminum in your diet. I do NOT recommend baking directly on either Nordic or Vollrath quarter-sheets: food spot will be permanently baked into the pans, black scorch marks and carbon deposits will permanently cook into the aluminum sheets and there is no easy reversal (if at all). I know, it’s only $15 a quarter-sheet so it’s not too expensive. I happen to like my things to last for years. :-)I hope this has been helpful. Write me comments if you need to ask more questions. I am attaching 8 or 9 photos to help with this review. Thanks!! Happy shopping!!These are wonderful sheet pans. These Aluminum pans have great heating capacity. I particularly like how easy they are to clean. DO NOT PUT THEM IN THE DISHWASHER. They will loose there sheen. The bright finish of aluminum is what makes them easy to clean. After they have been through roast chicken and vegetables or the like and have black goo covering them. I just put them in the sink (1 at a time) cover them in HOT water with a little dish soap. Let them sit for 20 minutes. I am always surprised how easily all that black is rinsed off and I have my brilliant aluminum pan back. No scrubbing involved.I guess you could call me a "LAZY CONSUMER" for I rarely give reviews, which is very wrong, for I rely on other consumer's reviews. So I guess I have to be very impressed or very unhappy for me to be compelled to write a review. These bakeware are "AWESOME" I have a oven that has two separate oven in which the top is small and the bottom is large normal size. The upper I use most often, because it is quicker and I do not have to wast electricity warming up an entire stove to cook for just two people. It also is my main go to for baking etc. However, I soon found out that my Wilson bakeware Non Stick would warp in the upper oven. So I began looking for bakeware that would have a higher heat tolerance.I have NEVER used a non stick bakeware before, but this was all I could find that would take the heat. as advertised. Well let me tell you. I am in love now and abscessed with this Brand. I also find that it is easy to make non stick. Also once I thought about it I forgot that I most always use aluminum foil to save clean up. I now have tossed my Wilson bakeware into my yard sale pile. I plan to purchase all of this brands array of bakeware as I can afford. But for now I have all the bake sheets and all sizes, as well as the rectangle cake pan with nifty lid, muffin pan. I highly recommend this Brand.These sheets are amazing. Classic Baking sheets that I will keep for the rest of my life, unlike the Teflon ones which scratch, rust and lose their toxic coating into the food. These sheets clean easily and look cool too. I love them. Fits British ovens perfectly.I wish I could say 5 stars but I have a standard size UK oven and they don't fit I'm absolutely gutted, I've thrown the boxes so can't return. Edit, it is my fault for not checking the measurements I'm just absolutely guttedOrder arrived from USA around 15 days earlier than scheduled. Pan look good strong and sturdy if somewhat shallower than I thought it might be. Lid clips on very well. This item shipped from the USA was cheaper than I have seen even with postage than on UK Cookshop site for the same pan with lid. Very pleased.Been looking for cooking trays that don't warp during normal cooking/baking processes. These are spot on and Ii would recommend you try them for yourself. I don't think you'll be disappointed.Bought to go with One Tin Bakes so just right
