We highly recommend using a galvanized Fire Pit Ring when building an above-ground fire pit. In addition, you can also install a Black metal fire pit ring which we think looks more attractive - but they are painted, not galvanized.
The ring size and configuration (Round or Square) will determine the size of the fire pit.
