Corten Steel Planters
A Living Finish. Built for Longevity.
Corten steel is widely used in garden and landscape design for its strength, durability and distinctive evolving appearance.
Often referred to as weathering steel, it is designed to form a natural protective layer as it reacts with the elements. Over time, this process creates a rich, rustic brown patina that not only defines its appearance but also protects the material from further corrosion.
This organic transformation makes corten steel a popular choice for architectural planting schemes in both commercial and residential environments.
Designed to Evolve Naturally
Corten steel planters are typically supplied in an unweathered or partially weathered state. Once installed outdoors, the weathering process begins.
Over a period of approximately 3 to 4 months, depending on climate and location, the steel develops its characteristic orange-brown patina.
Each planter evolves slightly differently, creating a natural, unique finish that matures over time.
We can also offer a pre-weathered service, where planters are delivered fully transformed with a consistent rustic finish.
Understanding the Weathering Process
During the initial weathering stage, corten steel will produce natural carbon runoff. This may result in temporary staining on surrounding surfaces such as stone or concrete.
To help minimise this:
-
All planters are supplied with discreet feet
-
This lifts the unit slightly off the ground
-
Reducing direct contact with surrounding materials
Once the material has fully cured and sealed, runoff reduces significantly or stops altogether.
As this process is a natural and essential characteristic of corten steel, care should be taken to protect surrounding surfaces during the early stages.
Built for Commercial Use
Our corten steel planters are manufactured to commercial-grade standards, using steel thicknesses ranging from:
-
1.5mm
-
up to 8mm
This ensures structural integrity, durability and suitability for large-scale or high-traffic environments.
All products are supplied with a 5-year manufacturer’s guarantee, providing confidence in long-term performance.
