All decorative, no weight bearing at all. They'll be drilled through in 4 places and screwed to a wall (with small tube standoffs).

Being as most of the welds are on 16ga 1/2" square tube I figured the .023 would be the better choice. No? I'd have to check, I think I only have .030 in flux core, being decorative, I didn't feel like dealing with the spatter.
