Main Question or Discussion Point
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?
