36 inch Inner Fire Pit Ring, 40 inch Outer Steel Fire Pit Insert

In this review the 36 in Inner Fire Pit Ring with a 40 in outer size is presented for homeowners who want a straightforward steel liner to build or upgrade a backyard fire pit. The ring's main appeal is its simple, heavy-duty metal construction and easy assembly: eight panels bolt together in minutes to form a stable 36 in inner chamber that sits inside stone or masonry for a finished look. For people who want to DIY a tidy, durable fire ring without complex installation, this unit delivers the essentials.

Key Features

• Dimension: The insert measures 36 in inner width by 36 in depth and 9 in height, giving a roomy combustion area for logs and firewood.
• Outer size: The full assembled ring spans 40 in outer width and depth, fitting common stone piles or lined pits with some clearance.
• Thickness and finish: At about 1mm thickness with high-temperature resistant paint, the liner is protected against heat and weather for extended use.
• Quick assembly: The eight-piece design uses bolts through predrilled holes so most users can finish setup in about five minutes.
• DIY friendly: The ring works alone as a metal fire pit or as an internal liner inside stacked stone, letting owners customize the final appearance.
• Size options: The product family includes different sizes, so users can choose a ring to match the dimensions of an existing or planned stone pile.

Who It's For

This insert is best for homeowners and renters with an outdoor yard or patio who want a straightforward, installable fire pit liner that hides embers and contains heat. It is especially useful for DIYers building a stone or brick surround who prefer to set a metal ring inside the structure rather than build a full masonry combustion chamber.

It is less suited to people seeking a thick gauge, commercial-grade fire bowl or those who require a fully welded, rustproof stainless solution; a heavier gauge or different material may be preferable for permanent coastal installations or for those prioritizing maximum longevity over value.

Pros & Cons

Pros

• Easy to assemble in about five minutes using the supplied bolt holes and hardware.
• Generous inner dimension gives space for larger fires and better airflow.
• High-temperature resistant coating helps the ring withstand repeated use and outdoor exposure.

Cons

• The 1mm steel thickness is adequate for many backyard uses but may feel thin to those expecting heavier gauge metal.
• Finish may show wear over time with frequent high-heat use, though the coating is heat resistant.
