Would this work....? Im designing a folding bunk bed and was wondering whether to keep the weight down I could use a metal wire mesh material as the top bunk fixed to aluminium square tube? Also would it be possible to attach this to the tube main frame fairly easily and how much does the mesh weigh per m squared as iv done some research but cant find this detail out? The top bunk needs to support a load of 100kg in use. Thanks for the help guys.
