Available in 6 sizes: 6", 10", 11", 16", 22" and 28". Custom sizes also 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!
