I'm trying to build a frame out of super unistrut channel. Answered
I basically building a frame of a little house so that I can attached shade cloth to the top to shade my bonsai trees from the hot sun. I live in Texas and its hot! Also in the winter I'm going to but plastic on it and make it a greenhouse. I need something I can take apart and something that the wind isn't going to tear up. I have one made out of PVC pipe right now but the wind is picking away at it.
