Square Fire Pit Ring Insert, 42x42 in, Carbon Steel

Square fire pit ring insert creates a safer, cleaner-lined burn area for backyard fires by containing heat and protecting surrounding stone or brick. Built from heavy-duty carbon steel with a high-temperature black coating, this 42" outer / 36" inner fire pit liner delivers generous room for firewood and improved airflow for steady flames. Install it above ground as a standalone campfire ring or set it in-ground for a custom DIY fire pit build.

Whether you’re upgrading an existing fire pit or building a new square fire feature from the ground up, this steel fire pit liner helps keep your setup tidy, stable, and easy to maintain. The panel design makes transport and storage simpler than one-piece rings, while the 10" height helps contain embers and fuel. Pair it with pavers, stone, or brick for a custom look, or bury the base for an in-ground campfire area. Grab yours today and start building your next outdoor gathering spot.
