I am working on a design where we are looking to replace wire rack shelving with perforated metal. The shelves will hold liquid containers and need to be fairly flat. However, all the prototypes we have constructed suffer from an oil can type warping. The rack will bow up in the center and then as you put weight on it, it will suddenly pop down. We installed a support in the center however now we have two sections that bow - one on each side of the support that bow about half as much. Adding more supports creates more sections that bow however each section bows less.
I understand that the perforating process stretches the material, however I am at a loss of how to address this. Adding lots of supports solves the problem but yields a fairly ugly and time consuming product. Anyone have any ideas on how to reduce the warping?
