    Is it aluminium or steel ? if it is aluminium I would go to 6mm thickness, if steel you might consider 5mm thickness.
    I can't be certain but according to the spreadsheet it looks okay. If you filled it with epoxy and filler it would be stronger and would not resonate anywhere near as much as an empty tube.

    Spelling mistakes are not intentional, I only seem to see them some time after I've posted

    with the round rails it will be fine IMO ...

    but if you had square rails then id go thicker

    +1 on filling it, mine has made a massive difference ... there is no ring when hitting the beam
