Small Curved Fire Bowls - Corten Steel from Harrod Horticultural New

Manufactured from Cor-Ten® steel which is extremely durable and weathers to a rich rust patina over time adding to the aesthetic appeal of these attractive firebowls. The rust layer forms a protective barrier protecting the blue steel beneath, this gives the steel superb strength and longevity. as the steel weathers the fire bowl may cause staining on the surface it stands on through carbon or rust run off.

The small curved fire bowls are available in 60cm and 80cm diameter. Each bowl has a stable welded base and has holes drilled for improved air circulation and drainage. The firebowls can also be used as a planter for shrubs, flowers and herbs. Iron Fire Bowl  stands are also available perfect for multi-purpose use. They can be used to lift the fire pit off the ground and help protect the lawn.

More information about Cor-Ten® Steel:-

Cor-Ten® Steel is a special steel originally developed for bridge building and skyscraper construction due to its incredible strength. When the steel weathers it develops a dense oxidisation layer which protects the blue steel inside. If this protective layer is compromised, it will simply form a a new skin to protect itself. This makes Cor-Ten® Steel extremely durable and gives it far higher resistance to atmospheric corrosion than other steels. 

Weathering New Corten Steel Products can take from 2 months to 2 years, depending on ambient conditions of where the corten is placed. Corten steel will produce a oxide run-off (rust, in a very fine particulate form) when weathering that will stain paved/stone/concrete (any porous surface). The run-off is perfectly normal and will decrease over time as the steel matures.

Fire Bowls – due to the intended use of the corten product there is nothing that can be applied to the steel to seal it, corten fire bowls will weather very fast with regular use. The oxide run-off will stain any surface they are placed upon. The fire bowls have holes in them one in the centre and the bottom of the bowl for drainage. Oxide run-off and ash is particularly prone to washing out of this hole when it rains.

When you first receive your Cor-Ten® Steel products they will arrive in an un-weathered or partly weathered condition. Once placed outside the weathering process will begin. This can take some time; the steel has a reactive patina period of between 3 and 9 months depending on location and climate. The patina or rust acts as a protective barrier - it will not penetrate or compromise the structural integrity of the material. The colouration of each item will vary as the weathering process takes place, eventually producing a rusty brown patina. 

Stage 1 - Freshly manufactured Cor-Ten® Steel. At this stage the dark oily residue coats the Corten Steel.

Stage 2 - The oily residue is beginning to break down, as the Cor-Ten® Steel begins to weather.

Stage 3 & 4 - The “Run-Off” stage – This can take around 3-9 months depending on weather and positioning.

Stage 5 & 6 - The final stages of the weathering process. Some “Run-Off” may still occur as the Cor-Ten® Steels patina develops to a striking more consistent appearance.

During the weathering process the Cor-Ten® Steel produces carbon run off or staining to adjacent materials such as stone or concrete. To reduce this possible staining, some Cor-Ten® Steel products are supplied with small feet or a stand, lifting the product and preventing direct contact with the flooring material. After the initial reactive period Cor-Ten® Steel will cure and self-seal with little to no carbon run off. The weathering process of Cor-Ten® Steel is integral to this product and as such we will not accept any responsibility for damage caused to surrounding materials as a result of carbon run off from Cor-Ten® Steel products. Please ensure you do not place your product on any surface that may be damaged during the weathering process.
