Load on RHS beam Load on RHS beam johnnytee (Structural) (OP) 19 Apr 16 09:50 Hi not sure how much weight(kg) this beam can take. 150mm x 50mm x 2.0mm gal steel and the length of beam is 5.040m? Want to hang sliding doors from it if it can cope with the weight Regards RE: Load on RHS beam Backcheckrage (Structural) 24 Apr 16 01:58 Definitely sounds like it won't work. I recommend something with at least a 6mm wall. It needs to be 100mm wide at least just for mating geometry to door head.
