I'm in the process of ordering 2 suare steel parking lighting poles from set of plans of spec. of Max Hight of 25' single 400W HPS fixture capable of wind speed of 110 MPH. Since Econolight, Lumark and Simkar list Wind speeds of 100MPH, the local elect. and bldng. inspector gave permission to use one of the listed poles. My question is there are two Thicknesses(Guages)-11GU(.120) or heavier 7GU(.180). and 4" or 5". Two suppliers quoted me for 11GU.-4"-20ft. I'm asking for knowledge from experience; would one or all options going larger 5" or 7GU or 22 ft pole be any better or a waist of money. If willing to spend extra few $'s. Owner is building 2' cement riser under each.
