Metal Fire Pits

Yes, most metal fire pits will eventually rust, especially when left outdoors in wet weather — even stainless steel is not fully immune. However, thicker steel (3–5mm) is far more resistant and can last many years outdoors with normal use. You can slow rust significantly by cleaning the pit after use, storing it in a dry place, and placing sand in the base.

Steel (especially stainless or Corten) offers the best balance of durability, heat resistance, and longevity, making it the most popular choice. Cast iron is extremely tough and great for cooking but is very heavy and can crack under extreme temperature swings if not maintained. Aluminum is lightweight and rust-resistant but may warp or melt under high heat, making it less ideal for intense, prolonged fires.

You should never place a wood-burning metal fire pit directly on a wood or composite deck, as the base gets extremely hot and can ignite combustible surfaces. For patios made of stone or concrete, use a protective barrier like concrete pavers or a fire pit mat, since heat from the base can stain, crack, or damage those surfaces too. Most propane fire pits can be used on decks if you follow the manufacturer's clearance guidelines and use a heat-resistant mat.

Metal fire pit prices vary widely depending on size, material, and design. Basic wood-burning metal models can be found for under $100, while freestanding powder-coated or stainless steel fire pits typically range from $300 to $2,000 or more. Custom-built or permanently installed fire pit features can cost anywhere from $1,000 to $5,000 or more.

Yes, it is always recommended to cover your metal fire pit when not in use, and some manufacturer warranties actually require it. Leaving it uncovered can allow water to get inside the burner and gas line, causing costly damage, and also lets leaves and debris accumulate. A snuffer lid or fitted cover will help protect the metal, extend its lifespan, and keep it clean between uses.
