anyone have a chart or know what is the amount of weight that can be applied to 1 1/4" square tube with 1/8" wall at a span of 5 foot to achieve minimum deflection ... . I have been using it for handrail for per a customer's specs, & did some for another customer that is questioning the size of it. all OSHA says is strong enough to withstand 200 lbs with minimum deflection TIA Rob
