In addition to being incredibly strong and durable, Corten Steel requires no maintenance. It is extremely popular for its warm rich, rust finish; something not usually associated with metal. This guide will equip you with all the vital knowledge required to own a Corten Steel planter.
When you first receive your Corten Steel planter, it will be at any point throughout the weathering process; on exposure to the elements, Corten Steel develops a protective layer of rust which acts as a shield for the blue steel inside and prevents further corrosion. This is part of the steels weathering process which we have broken down into several detailed stages to help you understand where in the process your Corten Steel is, and what to expect next:
- 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.
What is “Run-Off”? During the weathering process the Corten Steel produces carbon run off or staining to adjacent materials such as stone or concrete. To reduce this possible staining, some Corten 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 Corten Steel will cure and self-seal with little to no carbon run off. The weathering process of Corten 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 Corten Steel products. Please ensure you do not place your product on any surface that may be damaged during the weathering process.
