Also Top, they make strap on steps now to use on public lands instead of the screw ins. They also make nice ladder type steps, strap on, with 3 or 4 steps on each piece. I prefer the hang on's for several reasons but the MAIN one is weight. Them dang ladder stands, while yes they are nice and easy to set up and get in and out of, are friggin heavy and very hard to manage. Especially if you hunt out in no mans land where I go. Haul one of them Ladder rigs a mile or so in the heavy brush and you will NEVER do it again!
As far as the posters question goes, you have scrap metal there. Should be high end aluminium so you should get a few bucks for it. Other than that it is pretty much worthless unless you take bugsnbows advice. That would make a very nice trellis!
