Fire Pit Art Asia 48-Inch Wood Burning Fire Pit. AS 48. Fire Pits. Hand-crafted in the United States, Fire Pit Art fire pits are constructed with durability and creativity in mind. The Asia fire pit is four feet wide at the top for a large viewing area from any angle or height. The design has a curved bowl resembling a wok and is constructed from heavy duty 1/4-inch thick carbon steel to make it one of the most durable steel fire pits on the market. The inner bowl is coated with a paint that is resistant to high temperatures, while the outer side has a maintenance-free, iron oxide patina that will darken over time. A drain in the middle allows rain to escape to prevent rusting. Each fire pit is unique and is individually numbered by the artist on a brass plaque, so you know you are getting a one-of-a-kind piece.
