What Is a Fire Pit Ring Insert?

A fire pit ring insert (also called a liner) is a steel inner layer placed into a stone or brick fire pit surround. It differs from a fire pit ring, a fireproof framework set directly on the ground to contain flames.

The insert’s metal sheathing creates a heat and flame barrier that protects masonry walls from exposure to high temperatures and direct contact with the fire. Without one, the fire and heat can slowly damage and weaken the mortar and adhesives that hold the fire pit blocks together. If you want your fire pit to last a long time, installing a fire pit ring insert is the way to go.

Inserts come in various sizes, shapes and qualities. When choosing a fire pit ring insert, focus on these the features:

Material: Carbon steel, stainless steel, iron.

Durability: 10-gauge (thick) to 20-gauge (thin) metal.

Size: Outer and inner diameters.

Depth: Average is around 10 inches deep.

Shape: Round, square, octagon.

Price: $50 to $1,500+.
