Tank dimensions are 240x120x70cm (LxWxH), 15mm glass. Top frame of stand is made from 100x50x3mm steel, legs and base from 50x50x3, galvanised. Gussets are 120x6mm steel. The part I'm concerned about is providing enough support across the width of the tank, ideally I'd prefer not to have to put a row of legs down the middle, but if the 100x50 won't be rigid enough for the 120cm width I'll just go for 50x50x3 all round and put a row of legs down the centre. If anyone wants the sketchup files PM me with your email address and I'll send them to you.
