We always understand a good quality tray should be strong enough for bakery or any kind of food application for a long term use, while we can see lots of them are easily deformed and can not use in a long life cycle. But we are proud to bring you a better way of manufacturing, recently, we developed a 4 side aluminum tray for customers from Fiji, it is made of aluminum, but it is well folded and welded on 4 corners. My QC made some test and found the quality is good enough for an adult to jump on it, for more details, please kindly check the following picture and videos
