Heavy Gauge Steel Resists Corrosion over Time
The case of the kiln is fabricated from a heavy gauge (1/8" thick) steel plate with structural steel members.
Contrast this with some other front-loading kilns on the market that use thin gauge (1/16") sheet metal.
Steel Case is Powder-Coated for Corrosion Resistance and Professional Appearance
The entire case, after it has been fabricated is powder coated with a baked-on temperature-resistant hammertone finish.
This is the best coating you can get and is far superior to a spray-painted finish, especially where water-based paint is used. Powder coating will resist chipping, scratching, and corrosion.
