I make this from recycled 16-gauge steel, cutting it with a Plasma Cutter. I then polish it and color it with a 6000 degree torch. Powder-Coated to prevent rusting. Available in 6", 8", 10", 13", 16", 19", 22", 26" and 30". The first picture is for all sizes EXCEPT the 6". The second picture is the 6". Custom sizes available starting at 6".
