Hi all, I have a nice open generic question to start this board: I'm working on a product which will likely be predominantly manufactured from box section steel/aluminium sections. Strength is key, but I also need to reduce the weight of the overall structure. The product needs to be portable and also lift weights approaching 300kg. I'm wondering if there is an alternative method to welding, or a different production technique which will maintain strength but reduce weight. Would an alternative material open more options? Any feedback welcome- Enjoy!
