Heavy-Duty 4 mm Steel
Our large fire boxes are manufactured from substantial 4 mm mild steel, measuring 500 × 500 × 380 mm and weighing approximately 30 kg. Our Flat Pack Fire Pits are 400 x 300 x 300, made from 2mm mild steel weighing only10kg.
Naturally Weathering Steel
Our fire boxes are supplied in their natural, unpainted mild steel finish. Over time, exposure to the elements creates a distinctive rustic appearance, giving each fire box its own character. No artificial rust finish or decorative coating is applied.
Engineered Ventilation
Carefully positioned ventilation holes and decorative laser-cut details allow air to circulate through the fire box while creating a striking glow when a fire is burning.
Practical Flat-Pack Design
Our innovative interlocking construction allows our fire boxes and pits to be dismantled. Easier to transport, store and assemble, without permanent welded joints.
