Astro Fire Sculpture in Corten Steel: a low rust-finish half-sphere around the flame

The Outdoor Plus Astro fire sculpture in Corten steel is a low, wide fire feature in a 30, 36, or 48 inch size shaped like a half sphere, built from curved vertical staves with narrow gaps between them, so the fire glows out through the sides. It rests directly on the ground, and Corten forms its own protective rust-colored skin outdoors with no paint or sealer needed.

Burn firewood in it as it comes, or order it as a gas feature for natural gas or propane and light it with a match or a push-button igniter. Decorative gas burner ornaments are optional. Want it bright instead? See the Astro in stainless steel. The Corten Astro fire sculpture ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

What is Corten Steel

COR-TEN® Steel is a high strength steel with a high weathering resistance. COR-TEN® has been a trademarked name used to generalize Weathered Steel. This steel alloy has been used in architecture and sculptural works, it eliminates the need to paint and provides a beautifully unique and aesthetically pleasing look while also providing great rust protection. COR-TEN® has a weather resistance greater than 4~8 times that of ordinary steel. Each of our COR-TEN® Steel Products at The Outdoor Plus are aged to look around 1 month of patina. The texture of the COR-TEN® Steel may be irregular, this is what gives our products and even more unique finish.

Corten Steel Fire Pit

 

COR-TEN® Steel will continue to patina over time into a darker mocha looking metal instead of the bright yellow-orange that it originally started with. The image below shows the aging/patina process of COR-TEN™ Steel starting from left to right(0.5 Months, 1.5 Months, 6 Months, 2 Years, 5 Years, 22 Years, 40 Years).

FAQ

Why is the Astro Fire Sculpture supposed to rust?

Because Corten is weathering steel: outdoor exposure builds a stable rust-orange patina that protects the metal instead of corroding through it. Your Astro arrives raw, shifts from steely gray to warm amber and umber over the first few months outside, then holds that earthy tone for years with no paint or sealer.

What sizes does the Corten Astro come in?

Three sizes: 30-inch (TFL-AST30CSWB), 36-inch (TFL-AST36CSWB), and 48-inch (TFL-AST48CSWB). The 30-inch suits an intimate patio corner, while the 48-inch Astro reads as a true garden centerpiece. Dimensions and clearances are on the spec sheet linked above.

Does the Astro burn real wood?

Yes — the Astro is a wood-burning sculpture at heart, built for real logs, crackle, and embers glowing through its laser-cut pattern. It anchors any wood burning fire pit setup with far more artistry than a plain steel ring.

What is the best way to start a fire in the Astro?

Build small: a teepee of dry kindling in the center of the Astro, a few fire starters underneath, and split hardwood added once it catches. The cutouts in the Corten shell pull air through naturally, so the fire draws well without fanning — seasoned, dry wood is the whole trick.

What should I do with the ashes afterward?

Let the Astro cool completely — 24 to 48 hours — then scoop ashes into a metal can with a lid, never plastic. Embers can stay live longer than they look. Cold wood ash from clean firewood can go in the garden or compost in thin layers.

What distance from the house does the Astro need?

Give a wood burner like the Corten Astro at least 10 to 20 feet from your home, fences, and anything overhanging — branches, pergolas, awnings. Set it on stone, pavers, or gravel, and check your local fire ordinance, since setback rules vary by city.

Will the Corten finish stain my patio?

It can early on. While the Astro is actively weathering, rain carries rust runoff that may tint porous concrete or light pavers. Set it over gravel, dark stone, or a protective mat for the first season; once the patina stabilizes, runoff drops off dramatically.
