    No, I mean 500 kilograms, 500 kilo-newtons, 500 kilo-pounds, ...

    What are the units for your load?
  7. ok thanks .. its kilograms. new at this. thanks again.
  8. Just want to point out that if you are designing this for a structure, especially one which people will be using, you MUST check your local and federal building codes. It may also be required that a certified structural engineer stamp the work.

    500 kg huh? Where did this figure come in? Did you account for seismic loading? Wind? Snow/rain? etc

    A 40 foot span is nothing to be approximating at.
  9. No people will be on or under structure. and it will be inside of my barn. I have 6, 10 foot HSS 6" x 4" X 1/4". Just wanted to see If I could them on this project.

    ThankĀ“s for your help

    We don't give this sort of advice here. If you don't know what you are doing, you need to find a local source of info (a structural building expert) and have them help you.
