All fire pits are made from 3/16" plate steel that is cut on our CNC plasma table. They can be made with or without drain holes depending on your prefernce.
They are fully welded inside and out, so no assembly is required.
The outside welds are ground down to give them a smoother look.
They are painted with high temp engine paint that is rated for up to 500 degrees, but can also be left unpainted to let them naturally rust over time.
