The Rheem gas heater has a polyester-coated, non-corrosive cabinet that is more durable than solvent borne- and water borne-coated metal cabinets. Every piece of sheet metal goes through a 7-stage wash system, making certain the powder paint has a perfect bond. Underneath the tough, yet beautiful finish you will find galvanized metal that offers superior rust prevention and years of durable service
