Our first round outdoor firepit 35" in diameter. 4" off the ground on the outside perimeter and 3" at the center. Made from 5/8" railroad spikes. It’s a beast and made for bonfires... we can make these as large as needed, or as small as needed. Just know over 36” there is a shipping surcharge. Not by me, but by carriers.
***Grates do not last forever based on your usage grates will degrade over time and, well, fall apart. We build for two requirements; aesthetics and durability, however our grates will wear out because long-term heat and weight will destroy the steel.
