What are the advantages of corten steel?

A corten steel plate is an element of construction and decoration that is both aesthetic and durable. Here are those 3 main benefits.

Its unique aesthetic

With a raw and warm aesthetic, this material goes perfectly with urban decors as well as more natural ones. Moreover, it is used in modern architecture as well as in the layout of gardens and parks.

Its great resistance

With its protective rust patina, the resistance of a material used in maritime freight and the rail industry is well established. Thus, a plate or a corten steel sheet is not likely to perforate, unlike standard steel which rusts and ends up being pierced.


Also worth noting, corten steel also has a high resistance to tensile deformation.

Corten steel does not require any special maintenance

No maintenance is necessary since the corten steel in the garden or as a construction element has the property of self-protection. Indeed, the formation of the patina on the surface prevents the progression of corrosion.


For those who wish, it is still possible to apply a rust remover to stop oxidation and fix the rust.

How long does it take for corten steel to oxidize?

The oxidation process can take several months. Naturally, corten steel oxidizes in about 6 months. This oxidation time depends on external conditions and the alternation of dry and wet periods.


The stabilization of the surface of a corten steel plate takes between 1 and 3 years to complete. However, it is possible to use a rust accelerator to speed up the process and thus obtain a rusty surface in a few hours.

How to accelerate the oxidation of corten steel?

The most natural trick is to spray the surface with salt water or vinegar. Spray your mixture of water and salt (or vinegar) on the corten steel surfaces daily and let dry. The rust should appear quickly.


You can also buy a rust accelerator commercially. However, take your precautions with the product by respecting the recommendations for use on the label and by protecting your eyes and skin to avoid the risk of burns.

Is corten steel bad for the environment?

The answer is no, corten steel oxidation produces rust which consists of iron oxide. It is not dangerous for the environment or for the fauna and flora.


In summary, the corten steel makes each work and each landscaping a unique and exclusive project. It is a trendy and design material for any outdoor space both in your garden and on your terrace.
