Because of the high aluminum pricing, I am buying used aluminum. It is sold at surplus aluminum price, which at this time, is 2 bucks a pound. These fences yield somewhere around 15 1 x 1 square tubes, with 1/16 wall. Each tube will come to around 75 inches in length, and each section usually sets me back about 75 bucks. I ended up using 3 of these sections to complete the project.
