I know this might not be the right forum for this question but all help will be appreciated.


I am about to do a new project which consists of a heavy punch bag rig, pull up bar and dip bars. It is my first time using galvanised steel tubes.


I have attached a diagram of the project below. Can you please have a look at the diagram attached and let me know if I can make it better and stronger.


I am thinking of using 48 size tube in 2m length for the punchbags which might add up to 125 kg if I hang up 2 punchbags at the same time. Will it be strong enough?


And for the pull-up bar and the dip bars, I want to use size 42 tube because size 48 is too big for my hands. Again the load might be up to 115kg.
I will be grateful if you can help me out on this. I worked for hours on this but I have a feeling it won't be strong enough.


Thanks in advance20200527_235641.jpg
