Alright I just came back from Home Depot and I noticed something. The 1 3/8 inch fence top rail is 16 gauge galvanized and 10ft 6in long. The 1 1/4 inch EMT Conduit is larger outer diameter or so it seems. I suppose its inside diameter v outside diameter. Suppose which one would be stronger, The price is not greatly different. The schedule 40 Ridged conduit I am betting is what I have outside the house now but 10ft of that is 30$. I am unsure of how strong a section joint would be in the middle of two pieces standing upright although it being threaded on each end I could cut one piece in half and connect to each end of a full piece that would likely be pretty strong but costly.
