Our Planter kit makes a good gift.
Heavy 14 ga steel arrives with bent flange on the panels.
Paint or allow to rust outdoors. Generally the plant stays in a plastic container and is spaced up near the top.
Pictured complete unit is tack-tack welded but you can fully weld the seams too (pic 3).
Get creative with it.
As always, grinding welding and painting are required.
Approx size is 12x12x24 tall.
