Koutemie 35" Steel Fire Pit Ring Liner — 31" Inner Diameter, Heavy-Gauge Black Powder-Coated Insert

The Koutemie fire pit ring liner is a heavy-gauge steel insert — 35-inch outer and 31-inch inner diameter — designed to convert any DIY ring or in-ground hole into a safe, long-lasting outdoor fire pit.

This solid metal firepit rim is built for homeowners, campers and weekend builders who want a durable, predictable core for backyard bonfires, campsite rings or patio fire features. Powder-coated black steel resists heat and provides a defined combustion chamber that keeps embers contained and simplifies maintenance. The kit ships in seven pieces for compact transport and fast assembly, so you can make a usable fire pit on grass, gravel, patio brick or a built-in masonry surround.

How does this liner improve safety and cleanliness?

The steel ring creates a continuous barrier around burning wood, reducing wind-driven sparks and confining ash to the fire area. Because it prevents gaps between stones or loose soil, the liner helps keep embers from falling into surrounding material and makes post-fire cleanup quicker.

• Solid-steel wall contains flames and coals within the 31" inner cavity.
• Heat-resistant finish reduces surface corrosion for repeated use.
• Removes loose-soil collapse risk when used as an in-ground liner.
• Limits ash scatter, simplifying sweeping and disposal.

Can I customize the pit or install it in-ground?

Yes — the ring is designed to accept brick, block or stone surrounds for a finished aesthetic, or it can be set directly into an excavated hole for an in-ground pit. The product intentionally has no bottom so you can choose a sand, gravel or natural-earth base to suit local codes and preferred drainage.

• Fits inside masonry or stacked-block rings as a protective inner sleeve.
• Drop-in installation into a prepared hole with a sand/stones base.
• Use with pavers or decorative rock around the outer edge for curb appeal.
• Assembles in minutes from the included 7-piece kit without special tools.

What are the dimensions and material details I should know?

The fire ring measures 35 inches across the outside and provides a 31-inch clear inner diameter for fuel and airflow. It’s fabricated from thick steel for structural strength and longevity, with a black finish to minimize visible wear between uses.

• 35" outer diameter, 31" inner diameter — suitable for medium-sized gatherings.
• Heavy-gauge steel construction for repeated high-heat exposure.
• Seven-piece sectional design for shipping and easy assembly.
• No bottom plate — accommodates custom base material and drainage.

How do I maintain and protect surfaces beneath the pit?

Because the liner transfers heat to whatever sits beneath it, always place at least a layer of sand, stone or pavers under the ring to protect grass, deck or soil. Allow the fire to burn down to embers and cool before cleaning; remove ash into a metal container once fully cold.

• Use a sand or gravel underlayer for in-ground setups to protect soil and improve drainage.
• Place on a non-combustible base (pavers or flagstone) when used on patios or decks.
• Do not leave fires unattended; follow local fire regulations and permits.
• Store dry and cover between seasons to slow surface rusting.

Who is this for: The Koutemie 35-inch fire pit ring liner suits DIY landscapers, campers who want a portable heavy-duty insert, homeowners creating a custom backyard fire feature, and community or park stewards needing a reliable, replaceable metal core. If you want a simple, sturdy steel sleeve to contain fires, speed cleanup and serve as the structural heart of a built or in-ground pit, this ring provides an affordable, easy-to-install solution.
