Explanations of the corten alloy

Corten steel is a self-weathering steel valued for its warm, natural, and evolving appearance. Composed primarily of iron with small amounts of alloying elements such as copper, chromium, nickel, manganese, molybdenum, vanadium, titanium, niobium, aluminum, and phosphorus, it is designed to develop a protective patina when exposed to air and moisture.

This surface oxidation layer, with its rich orange, brown, and copper tones, acts as a natural barrier against corrosion. Unlike conventional rust, which can weaken metal over time, the patina of corten steel helps stabilize the surface and protect the material in depth when exposure conditions are appropriate.

This unique behaviour makes corten steel a durable, aesthetic, and evolving material for outdoor furniture, architectural elements, planters, decorative panels, and landscape projects. Over time, each piece develops its own distinctive finish, shaped by its environment, the seasons, and the way it is used.

A living material that can be refreshed and renewed over time.

Corten steel is a living material whose patina develops naturally through exposure to air, moisture, and time. This controlled oxidation process creates a protective surface layer with warm tones ranging from orange to deep brown. Depending on the environment and its exposure to rain, sun, wind, and the changing seasons, the patina may continue to evolve, stabilize, or gradually darken over the years.

When desired, this oxidation process can also be supported or reactivated to help even out the surface, revive the colour, or restore brightness to an older piece. Through proper cleaning, surface preparation, and patina reactivation techniques, corten steel can regain more luminous and vibrant tones.

This allows the material to be visually refreshed while preserving its natural character and evolving beauty.

The Corten Philosophy

The Corten philosophy is about allowing time to do its work. It means embracing the natural evolution of the material without trying to control it completely. Just like corten steel transforms with the seasons, this approach invites us to let go, follow the rhythm of the journey, and find beauty in change.

It is rooted in a respect for raw, authentic materials: their tones, their markings, their imperfections, and their living patina. Every transformation becomes a trace of time, a natural signature, and a quiet dialogue between metal, light, air, and the surrounding landscape.

To live the Corten philosophy is to choose a beauty that is organic, lasting, and honest. It means creating with nature rather than against it, allowing the material to reveal its true character over time. The result is never static: it evolves, breathes, and tells a story that is entirely its own.
