Most outdoor fire pits and grills run on wood or propane. Some wood-burning models also list charcoal or other biomass fuels as usable options.
Common construction materials include stainless steel, steel, iron, terrazzo, and weather-resistant plastics such as HDPE.
Smokeless designs use bottom vents, double-wall or curved interiors, and directed airflow to promote secondary combustion — heating incoming air so smoke is reburned before it exits.
Heat output varies widely by design. Some wood-burning units list 0 BTU, while many propane fire tables commonly list outputs around 50,000–55,000 BTU; smaller propane columns are often listed near 15,000 BTU.
Some models double as a fire pit table, BBQ grill, or ice bucket, and others convert to a dining or serving surface when the fire feature is covered.
Many wood-burning designs include removable ash trays or pans that slide out for easy dumping. A few models advertise a two-step ash-tray removal process to simplify cleanup.
