Hey y’all, let me know if I screwed up beyond repair. I bought a bunch of old RV windows that I’m going to use in my bus and am starting the roofraise this Friday. Being unfamiliar with working with steel tubing, I did not think it out enough and went ahead and bought a listing I found on market place. It was $150 for 80 feet of galvanizedsquare steel tubing. The thing is, it’s only 1”x1” 16 gauge. Feels and looks WAYYY smaller than what I was imaging (which I’ve come to realize is probably 2x2 steel tubing). I really don’t want to have to toss these but they just don’t seem sturdy enough.
For more context, I’m framing the windows in the raise with these galvanized tubes. As a result they will be welded in between the hat channels once they’re cut and will be part of the structural support of the roof.
Here’s a pic of the tubes I got AND what I’m planning on doing with them. https://imgur.com/a/Afgwghj
Can you all give me feedback on whether these are too small/thin to use? And if so, what is something else I could use them for? I’m short on time and really don’t want to flush $150 worth of cut tubing away.
