The CorTen Steel Cube Planters start out as blue steel and as soon as the Corten Steel is exposed to the elements it will naturally weather and develop a rich eye catching finish. This natural fixed coating of rust provides protection against further corrosion.
During the weathering process the Corten Steel produces carbon run off which can stain adjacent materials such as stone or concrete. To reduce this possible staining, all products have small feet, lifting the planter and preventing direct contact with the flooring material. After the initial reactive period Corten Steel will cure and self-seal with little to no carbon run off.

More information about Corten Steel:-
Corten 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 Corten Steel extremely durable and gives it far higher resistance to atmospheric corrosion than other steels.
When you first receive your Corten 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; Corten 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 Corten Steel. At this stage the dark oily residue coats the Corten Steel.
Stage 2 - The oily residue is beginning to break down, as the Corten 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 Corten Steels patina develops to a striking more consistent appearance.
