Made from weathering steels

Weathering steel is versatile and can be used for facade or roof applications. It can be adapted to any building

type: from residential to leisure and everything in between. In both new and refurbishment projects, weathering steels create an innovative and different aspect. Thanks to its high strength, weathering steel is also ideal for lightweight extensions, particularly vertical extensions.

Weathering steels for cladding can be shaped into a wide range of geometries to achieve the required aesthetic.

Profiled sheets, cassettes, single sheet panels... a large range of building systems can utilise corten.

Alloy content and environmental conditions are key factors influencing the formation of an oxide film on steel. Under appropriate atmospheric conditions, Weathering steel develops a durable, tightly adherent protective oxide coating. The appearance, texture and maturity of this coating depend on three interrelated factors: time, degree of exposure and atmospheric environment. With time, the oxide coating changes from a “rusty” red-orange to a dark purple-brown patina. The moderately rough texture becomes more distinct as the coating thickens. This weathering process extends over a period of time and depends on the following factors:

• Degree of exposure has a strong influence on the weathering process. Steel exposed to rain, sun and wind weathers more quickly than steel in a sheltered location. The oxide on a sheltered surface tends to be rougher, less dense and less uniform.

• Atmospheric environment also impacts oxide development. Frequent wet-dry cycles – for instance moisture in the form of rainfall and dew that is dried by wind and sun – are key to the weathering process. • The degree of atmospheric contamination also has its effect. In moderate industrial environments, Weathering Steel usually matures rapidly and achieves the darkest possible tone. In rural locations, the oxide coating develops more slowly, and generally has a lighter tone. In arid climates, the weathering process is dramatically slower.
