OUSHENG 36" Round Fire Pit Ring Insert - 36in Heavy-Gauge Steel, 8-Panel DIY Backyard Liner

The OUSHENG 36" Round Fire Pit Ring Insert is a heavy-gauge steel liner designed for DIY stone, brick, or paver fire pits, offering a durable 36" inner fire chamber that’s easy to assemble and customize.

Turn a ring of stone or brick into a long-lasting backyard fire pit with this 36-inch insert from OUSHENG. Built from thickened steel with a heat-resistant coating, the kit includes eight interlocking panels, hardware, and a 39" outer lip to sit flush with your surround. It’s an insert only — no bottom — so it fits directly on soil, sand, or gravel and is intended to be encased by masonry, pavers, or stacked stones for a finished, professional look.

How does the open-bottom design work for DIY fire pits?

The open-bottom construction lets you place the ring directly on the ground or on a bed of sand or gravel, eliminating the need for a prefabricated base. This approach helps with drainage and allows natural heat dispersion into the ground while making it straightforward to build a stone or brick surround around the metal liner.

• Fits directly on soil, sand, or compacted gravel for easy installation.
• Designed to be surrounded by masonry, pavers, or stacked stone.
• No welded bottom — simplifies transport and reduces weight.
• Ideal for above-ground or partially in-ground installations.

Is the steel durable enough for frequent fires and outdoor exposure?

OUSHENG uses heavy-gauge steel with a black powder coating to resist initial corrosion and weathering. For longer life and to protect the finish from heat discoloration, the manufacturer recommends a high-temperature spray paint application before first use, which helps preserve appearance and slows surface wear.

• Thickened steel construction resists deformation from high heat.
• Black powder coat provides baseline rust and weather resistance.
• Applying high-temperature BBQ or stove paint before use extends lifespan.
• Recommended maintenance: periodic cleaning and touch-up paint as needed.

How easy is assembly and transport for camping or seasonal use?

The ring ships as eight interlocking panels with pre-drilled holes plus screws and nuts, so assembly requires only basic tools and takes minutes. Its multi-panel design breaks down for compact storage and easier transport, making it suitable for backyard use, seasonal placement at a vacation home, or taking along for campsite gatherings.

• Eight panels with improved hole alignment for a snug fit.
• Includes screws and nuts; simple hand tools needed (not specialized).
• Breaks down for storage and fits in most vehicles when disassembled.
• Portable enough for occasional relocation or campsite use.

What size of fire can it accommodate and what fuels work best?

With a 36" inner diameter and a 39" outer diameter including the lip, the insert creates a large, deep chamber that holds substantial logs and kindling for cozy fires. It’s well suited to seasoned firewood, larger branches, and natural fuels; avoid burning trash, treated wood, or materials that emit toxic fumes.

• 36" inner diameter holds large logs and multiple fuel sizes.
• Deep sides help contain embers while allowing airflow for sustained burn.
• Compatible with wood, clean natural brush, and seasoned firewood.
• Not a complete pit — must be encased by masonry or pavers for finished look.

Who is this for? The OUSHENG 36" Round Fire Pit Ring Insert is aimed at homeowners, landscapers, and DIYers who want a sturdy, customizable metal liner to build around stone or brick. It’s a good fit for people who want a large fire chamber, straightforward assembly, and the flexibility to design their own exterior finish. If you need a full freestanding fire bowl with a bottom or a decorative finished product out of the box, consider a complete pit; if you plan a custom masonry surround, this heavy-gauge insert provides a durable core for many seasons of use.
