Available in 6" X 6", 10" X 10", 16" X 16" or 22" X 22". Custom sizes available. I make this from 16 gauge steel and cut this with a hand-held Plasma Cutter, then polish it and heat with an Oxygen-Acetylene torch to create the beautiful blue/brown finish. The final step is clear Powder Coating which preserves the finish and prevents tarnishing and rusting and allows you to hang it anywhere - outside or inside!
