Comzinn 36 Inch Fire Pit Ring Insert — 36in Inner / 40in Outer Steel Liner, 1.5mm Matte High‑Temp

The Comzinn 36-inch inner fire pit ring insert is a heavy-gauge steel liner that transforms a backyard hole or above-ground ring into a durable, safe-burning wood fire pit.

Built from 1.5mm steel with a matte high-temperature coating, this circular insert is designed to stand up to repeated outdoor use while keeping flames contained and easy to manage. Its 40-inch outer diameter and 36-inch inner diameter give you a roomy combustion area for logs and kindling, and the bottomless design lets you place it directly into a dug pit or use it on level ground with a sand or stone base.

How does this fire pit liner hold up to regular outdoor use?

The Comzinn fire ring is constructed from thickened steel and finished with heat-resistant powder coat to resist warping and surface wear. Robust panel construction and secure fasteners allow it to maintain shape through many burn cycles.

• 1.5mm steel plate for enhanced rigidity and impact resistance
• Matte high-temperature coating to reduce surface oxidation
• Eight-panel assembly for even heat distribution and structural stability
• Curved edges to minimize deformation at the rim

Can I install this ring flush with the ground or use it above soil?

Yes — the ring is designed for flexible placement. It can sit on top of compacted sand or stones, or be lowered into a shallow excavated cavity to create a semi-buried pit when you want a lower-profile fire.

• Bottomless design permits direct-ground installation or inset placement
• Recommended to line the base with sand or gravel for drainage and insulation
• Screw-assembled panels make removal and storage simple
• Works on patios, lawns, campsites, and backyard fire circles

How much wood and heat space does the 36" inner diameter provide?

The 36-inch inner chamber gives ample room for medium to large logs and longer burn sessions, while the 8.3-inch height contains sparks and maintains airflow. This size balances fuel capacity with efficient oxygen flow for clean, steady combustion.

• 36" inner diameter accommodates larger rounds and stacked wood arrangements
• 8.3" height helps contain embers without overly restricting airflow
• Wide opening simplifies feeding and tending the fire
• Generous surface area for group gatherings and cooking accessories

What safety and user-friendly features does the design include?

The ring includes rounded metal edges to reduce cuts during handling, and the powder-coated finish lessens surface flaking. The removable panel design also permits easy cleaning and replacement if a section becomes compromised over time.

• Smooth, curved rim edges for safer assembly and loading
• Panel-by-panel construction for straightforward maintenance
• Stable circular shape reduces tipping risk on flat surfaces
• Portable sections allow transport and compact storage

Who is this for? Homeowners and outdoor enthusiasts who want a sturdy, reusable steel liner to create a custom 36-inch fire pit will appreciate the Comzinn insert. It suits DIY builders who prefer a bottomless ring to set into a dug pit or place on prepared ground, and it’s practical for people organizing backyard gatherings, camping trips, or seasonal bonfires who value durability, easy assembly, and a roomy burn area.
