Corten steel looks fantastic, but is it safe for garden use? Corten steel has been increasingly used in recent years as a viable material for domestic gardening and commercial landscaping. Being a type of weathering steel, it has a protective layer of corrosion resistant patina that gives it versatility as well as desirable aesthetic qualities.
Naturally, people have concerns about Corten steel and weathering steel in general.
Weather-resistant steel as planters
The protective layer of rust that develops on weathering steels is safe for plants, not only because the amount of iron, manganese, copper, and nickel are non-toxic, but also because these micronutrients are important for growing healthy plants. The protective patina that develops on the steel is useful in this way.
But there are architectural studies that suggest corten A steel could be an environmental contaminant in large amounts, in conditions that speed the corrosion process. Note these studies are not relevant to corten B steel or Redcor. So large amounts of corten A may have a chemical composition that is detrimental to the environment. But in smaller amounts, corten steel material in the right environmental conditions is non-toxic.
Therefore, weathering steel as a garden flower pot not only has no harm to the growth of plants, but also has the advantage of supplementing metal elements. Weathering steel is very safe and beneficial to your garden. Come and contact us to help you customize your garden.
