Koutemie 40" Steel Fire Pit Ring Liner — 36" Inner Ventilated Smokeless Rim, Heavy-Duty Black

The Koutemie 40-inch steel fire pit ring liner is a heavy-duty, ventilated metal insert that converts an outdoor pit into a cleaner-burning, customizable 36-inch fire ring for above-ground or in-ground use.

Built from high-temperature steel and engineered with a top ring of ventilation holes, this fire pit rim is designed to improve airflow and help wood burn more completely while containing ash and embers. Its 40-inch outer diameter and 36-inch inner diameter give you ample fire area, and the unit is lightweight enough for DIY installations using bricks, blocks, sand, or dirt as the base. The black finish is practical and unobtrusive for backyard, campsite, or park use.

How does the ventilated rim reduce smoke compared with a plain ring?

The top circle of holes increases oxygen flow directly to the burning wood, encouraging hotter, cleaner combustion so less unburned particulate becomes visible smoke. Better airflow also helps coals form faster and improves fuel efficiency, which means less constant tending.

• Perforated top ring channels air to flames for more complete burning
• Reduces visible smoke by promoting hotter combustion
• Helps coals develop faster, lowering wood consumption

What materials and construction make this fire pit suitable for repeated use?

This liner is stamped from high-temperature steel chosen to withstand frequent heating cycles and help contain ash inside the ring. The metal wall prevents embers from escaping through gaps, and the simple, solid design minimizes weak points that can warp or crack under heat.

• High-heat steel resists warping from repeated fires
• Solid rim keeps ash and debris contained for cleaner surroundings
• Black finish hides soot while remaining low-maintenance

How easy is it to install and adapt for different outdoor setups?

Installation is straightforward and geared toward DIYers: the ring can sit inside a brick or block surround, be used as a freestanding above-ground pit, or be set into the earth for an in-ground look. There’s no bottom plate, so a sand or stone base is recommended to protect the ground beneath the fire.

• Fits a 36" inner combustion area—plenty of room for logs
• Works with brick, block, sand, or dirt for customized builds
• Assembles in minutes without specialized tools

What safety or prep steps should I follow before lighting a fire?

Because the ring has no bottom, always prepare a noncombustible layer—sand, gravel, or flat stones—beneath the liner to protect soil and reduce heat transfer. Keep the surrounding area clear of flammable materials, and follow local open-fire regulations and common-sense fire-safety practices.

• Place sand or stones under the liner when using directly on soil
• Set up at a safe distance from structures and low-hanging limbs
• Have a water source or extinguisher nearby and never leave fires unattended

Who is this for? The Koutemie 40" fire pit ring liner is ideal for homeowners, campers, and park or event organizers who want a durable, easy-to-install metal insert that improves burn quality and keeps ash contained. It suits people building a custom fire feature with bricks or blocks, those who prefer a simple freestanding pit, and anyone who values better airflow for cleaner flames. If you're creating a backyard gathering spot or upgrading a campsite fire ring, this liner gives a practical, long-lasting core for safer, more efficient fires.
