The Quad Corten Steel Fire Pit by The Outdoor Plus combines a low, square body with the changing color and texture of weathering steel. Available in 36- and 42-inch sizes, both models stand 12 inches high, creating a grounded centerpiece for seating gathered around the fire.
Choose Corten for an evolving, earthy surface rather than a uniform metal finish. Its patina can complement stone, brick and planting, but the material also affects placement. Consider the paving beneath the fire pit and the way guests will move around it, since weathered steel can release surface residue and stain nearby materials.
Design & Construction
The Quad is individually handcrafted in the USA with a Corten steel body and a recessed burning area. Straight sides give the design a structured outline, while the weathered surface introduces variation against more consistent paving and furniture finishes.
Corten develops an oxidized outer layer that helps protect the steel beneath it from further corrosion. The Outdoor Plus describes its surface as progressing from brighter orange tones toward a darker mocha appearance over time. This is a developing patina rather than a fixed, painted rust effect.
The low profile makes the top visible from surrounding seats, so assess the weathered surround and decorative media together. A darker burner bed can distinguish the recessed opening, while an earth-toned palette creates a more blended composition. Expect variation across the surface rather than an exact match to a photograph.
The patina doesn't make the complete fire feature maintenance-free. Burner and ignition care remain separate from the weathering of the body. Follow the manufacturer's instructions and discuss any proposed coating or surface treatment with The Outdoor Plus before applying it.
Sizes & Specifications
Both sizes have a listed 165,000 BTU rating and a 12-inch body height. Moving from the 36-inch model to the 42-inch model increases the burning area from 32 × 32 inches to 38 × 38 inches. Choose the larger version for its proportions within the seating group and broader media bed, not for a higher listed heat input.
| Size | Dimensions (L × W × H) | Burning Area (L × W) | Listed BTU Rating | Suggested Fire Glass |
|---|---|---|---|---|
| 36-inch | 36 × 36 × 12 in. | 32 × 32 in. | 165,000 | 107 lb |
| 42-inch | 42 × 42 × 12 in. | 38 × 38 in. | 165,000 | 151 lb |
Burning-area dimensions describe the recessed opening, not the extent of the flame pattern. Fire-glass quantities are suggested ordering amounts. Follow the instructions for your selected burner and ignition system when determining media depth and placement. Listed BTU ratings describe burner input, not a guaranteed heating area.
Ignition & Fuel Options
Choose a natural gas or liquid propane configuration to match your planned gas supply. Have your installer confirm supply capacity and gas-line sizing, especially when the supply also serves other outdoor appliances. Plan an approved external tank location for propane rather than assuming the low body provides tank storage.
Six ignition options are available:
- Match Lit: Light the burner manually without an electrical connection.
- Match Lit - Flame Sense [LC Certified]: Manual lighting with flame monitoring that shuts off the gas if the flame goes out.
- Low Voltage Electronic [CSA Certified]: Electronic ignition for installations with a suitable low-voltage power supply.
- Plug & Play Electronic [CSA Certified]: Electronic ignition that connects to a suitable electrical outlet.
- Spark Glow: Battery-powered spark ignition eliminates the need to light the burner with a separate lighter.
- Fire Glow: Battery-powered spark ignition with thermocouple-based flame monitoring and automatic gas shutoff.
Review the ignition choice with your installer before completing hardscape or electrical work. Leave a clear approach to the controls that doesn't require reaching over the burner. For a staffed lounge, establish how the unit will be started and shut down while guests are seated.
Decorative Media & Accessories
The Quad includes a fire pan, burner, selected ignition system and lava rock. Optional fire glass changes the appearance of the broad burner bed. Choose a media color that works with the range of tones the Corten surface may develop rather than matching only its initial appearance.
Include the media order in your size comparison if you're choosing fire glass. The suggested amount rises from 107 pounds for the 36-inch model to 151 pounds for the 42-inch model, affecting the cost of the finished configuration.
Optional accessories include a Bullet Burner upgrade, glass wind guard, stainless steel burner lid and fitted canvas cover. Each size has its own catalog-listed accessories. Select them for the 36- or 42-inch model rather than estimating fit from the overall body or burning-area dimensions.
Plan separate surfaces for drinks and serving pieces rather than treating the surround as unrestricted tabletop space. Let the unit cool completely before fitting a lid or cover, and follow the manufacturer's instructions for protecting the burner and ignition components.
Placement & Installation
The Quad is intended for outdoor use only. Before ordering, have a qualified installer review the supporting surface, gas supply, required clearances and any electrical requirements. Keep ventilation openings and service access unobstructed.
Plan for rust-colored runoff when selecting the supporting surface and adjacent paving. Water can carry residue from the weathered steel onto nearby materials. Review drainage and surface compatibility before installation, especially with pale or porous finishes, rather than assuming any staining will be easy to remove.
Surface residue can also transfer through contact. Keep cushions and furniture from rubbing against the body, and don't use it as seating. Position the low square corners outside natural walking routes, checking the layout with chairs pulled out or occupied.
The larger model occupies more space in both directions, so assess clearance on every side rather than only between facing sofas. Preserve required separation from the flame as well as comfortable access into and out of the seating group.
Check gates, steps and turns along the delivery route. Confirm unloading arrangements and how the unit will reach its final location; don't assume delivery includes placement. Plan handling that protects clothing and surrounding finishes from surface residue.
For designers and hospitality teams, include weathering and potential runoff in the material approval and housekeeping plan. Maintain required circulation routes independently of the seating group, with access for operation and service. Installation must follow the manufacturer's instructions for the selected size and ignition system, along with applicable local requirements. Confirm any additional commercial requirements with the installer and local authority.
