Patina formation:
When exposed to the open air, Corten steel forms a layer of patina that is essentially a protective barrier. This patina, which has a rusty appearance, protects the steel from further corrosion.
Weather Resistance:
Corten steel was developed to eliminate the need for paint and forms a stable patina, which gives the steel a "rusty" appearance but actually stops the corrosion process in depth. This makes it highly resistant to extreme weather conditions.
Applications:
Due to its strength and durability, Corten steel is often used in bridges, chimneys, outdoor sculptures, and building facades.
Limitations:
Although Corten steel is known for its durability, it is not completely resistant to corrosion. In very humid environments or in conditions where it is in constant contact with water, corrosion can continue to progress under the patina.
Economy and Sustainability:
Since Corten steel requires less maintenance than other types of steel, it is often considered a more economical option in the long run.
Aesthetic Appearance:
In addition to its strength, Corten steel is also valued for its distinctive aesthetics. Its patina gives the structures a natural, earthy appearance that can be very appealing.
Environment:
The use of Corten steel can be more environmentally friendly than other solutions, as the absence of the need for paint reduces the emissions associated with the manufacture of paints and their application.
