Re: Question about metal frames
How about pallets? I took pallets, lined them up and connected together with 2x4's slipped thru the line, then drove in a T post every second or third pallet, comes out very sturdy. For the corners, I used 2 T posts in the first pallet, it slides up off the posts so is a slide up gate. Slide it back down. Takes a little bit precision to place the posts but if I can do it anyone can for sure! I of course had a bunch of pallets, 2x4's and T posts laying around.
