Steel Tubing Strength

  1. Mar 1, 2012 #1
    I am currently installing some sail shades in my back yard. The manufacturer is callin for 6" tube steel supports but I believe that 4" tube steel filled and compacted with concrete will provide more strength and resistance to buckling. Obviously I am concerned about price but want to do a great job. I am in Phoenix and do not need to worry about hurricanes or snow load. The pipes are both schedule 40 with 1/4" walls. Any thoughts?

    If you fill 4" tubes with concrete it will not buckle. Go with that, as long as you can install proper fixtures at the bottom.
