500 gallon propane tank with 2 doors cut in the side for a homemade bbq or smoker. The doors were cut with a plasma cutter for a tight fit, and the hinges are attached. The tank is 37 inch diameter, about 9 feet long and 5/16 inch thick. This would make a great welding project for the hobbiest, or a start for a potential business if no answer, PLEASE leave message! Thanks
