Will the corten steel planters stain the adjacent area?
We often get asked if the Corten Steel Planters will stain the adjacent area by producing rust runoff or by being in direct contact with the surface the planter sits on. Below are some pictures of a Corten Planter that has been weathering in the same spot on the patio for about four months.
How much rust run off is normal with Corten steel?
At this point the planter is weathered and the weathering steel should produce very little to no rust run off. A point to consider is that Corten Steel (weathering steel) seals and fully weathers best when it is repeatedly exposed to moisture and then is allowed to dry. Thus the amount of rust run off could vary by climate.
What is Corten steel used for?
Corten steel, sometimes called COR-TEN steel, is a weathered steel that’s resistant to corrosion. Because of its ability to form a protective layer of rust, corten steel is a popular choice for outdoor sculptures, landscaping, structure exteriors and other outdoor applications.
Are Corten planters suitable for rust free decks and patios?
Generally, If you cannot stand the ideal of the smallest amount of rust on your deck or patio Corten planters are probably not ideal for your application so consider other metal planter options like Stainless Steel or Powder coated aluminum.
How do you keep Corten from staining?
There are, however, ways in which this can be prevented. If a Corten planter is being installed next to paving, the most common solution is to leave a five-to-ten milimetre cement gap between the planter and the paving. If the installation is on a pedestal terrace system, a spacer will have the same result.
How long will Corten steel last outside?
Generally, Corten steel will patina or rust within 6 months of atmospheric exposure. Most weathering steel types need cycles of wet/dry weather to develop and oxidize. With the protective rust that provides corrosion resistance, Corten steel can last upwards of a few decades to over 100 years.
Can you prevent Corten steel from rusting?
It is even possible to completely prevent the corten steel oxidising with an anti-rust coating. So you can blend oxidised areas with non-rusted areas to create original designs.
Does Corten steel bleed rust?
Cor-ten can be challenging and even damaging to surrounding areas if used improperly. Rust bleeding or runoff from the steel surface can stain surrounding paint, stucco, stone or concrete.
Do you need to seal corten steel?

What is cold rolled steel?
Bare Cold rolled steel is used as a less expensive option to A606 Type 4 ( Commonly referred to as Corten ). Bare Cold Rolled is widely manufactured for a variety of different purposes including metal roofing and costs less. Both of these panels are completely different. However, they look similar in appearance. After installation and exposure to normal weather the surface of the panel develops a gorgeous rustic finish and texture. Corten contains copper, chromium, manganese, and nickel which makes this material more expensive. Corten resists the corrosive effects of rain, snow, ice, fog, and other meteorological conditions by forming a coating of dark brown oxidation over the metal, which inhibits deeper penetration and negates the need for painting and costly rust-prevention maintenance over the years. Corten will last longer and would be more desirable in harsh climates.
