The world of corten-steel

It is possible you have never heard of Corten-steel, or maybe you have. However, for your interest we will explain to you what it is and the reasons why it is a material of the past, present and, without doubt, of the future.

The difference

The majority of metallic materials, iron or conventional steel, suffer atmospheric erosion in the form of rust and deterioration. These processes usually mean that, without added protection, the material is rendered no good for decorative or architectural uses. This is where Corten-Steel shows the first great trait which marks a difference. Due to its chemical composition Corten-Steel reacts to corrosion, including atmospheric corrosion. It creates a film which acts against water and steam, protecting the material rather than rusting it. We can say it ‘self-protects’ and does not need the help of additional protection.


In its chemical composition Corten-Steel has high levels of copper, nickel and chrome. The orange/reddish tone of the material is precisely due to its composition, although its colour can vary in many chromatic tones. These tones change depending on the effects to which it is submitted. It is a material which is mostly used outside, although, more and more, it is being used in interior design, which also affects its final tonality.


Corten-Steel can be used for almost any construction purposes, from architectural to decorative, exterior or interior.It is a material prized in the industrial world for its characteristics.

It is also a very famous material, used a great deal in the latest architectural and sculptural constructions of landscaping in cities. This is why artists of the nature of Eduardo Chillida, Richard Serra o Marino de Teana frequently use it in their work. Corten-Steel has been seen in cities all over the world since the late 80s.
