How thick is the metal

This fire pit is made from various thicknesses of steel for certain components. The fire bowl has a sturdy bottom with punched side walls, which are covered in a mesh screen. After large, hot fires, the steel might begin to corrode, as with most fire pits in the market. Proper maintenance includes cleaning the fire bowl and coating the steel with a high temperature spray paint, which can be purchased from Lowes. Doing so will pro-long the life of the fire pit. If you have other questions regarding the fire pit, please contact customer service at 866.814.0585 M-F from 8-8 EST.
