Get the Look: Corten Steel Siding
In today's architectural field, the industrial aesthetic style is quietly emerging and becoming more and more popular. This style, with its rough, primitive texture, for the building a unique charm. In this trend, corten steel wall panels play an extremely important role and have become the material of choice for many architects to create individual buildings. Corten corrugated metal is widely used in all kinds of building projects because of its unique aesthetic appeal, excellent durability, extremely low maintenance costs and environmental characteristics.
I. What is Corten Steel Siding?
Corten steel siding is made from weathering steel, a material commonly used for siding or roof panels on outdoor buildings. Weathering steel corrugated metal naturally develops a protective layer of rust called a ‘patina’. This layer of rust slows down the rate of rusting compared to other steel alloys, while giving the panels an attractive, rustic, mid-century look.
In terms of longevity, weathering steel roofs have a much longer life cycle than regular carbon steel (with or without copper). In addition, weathering steel roofs are versatile as an architectural and decorative material for building facades, windows, floors, roofs, fences, screens, guards, gutters, etc., both indoors and outdoors, such as in gardens, parks, homes, rooms, or in places such as art galleries, museums, and memorials. This is due to the unique surface colour of weathering steel raw materials, corrosion resistance, high temperature resistance, high strength, high toughness and easy processing characteristics.
II. Why is Corten Steel Cladding So Popular in Architecture?
Aesthetic Appeal
The natural rust colour of weathering steel adds warmth and texture to buildings, creating a rustic, organic appearance that blends perfectly into urban and natural environments. Moreover, the patina changes over time, giving weathering steel a unique and continuously changing appearance. This is ideal for architects seeking a material that can evolve gracefully over time.
Durability and Longevity
Corten steel is extremely durable. Unlike other metals that require frequent maintenance to prevent rust and damage, weathering steel forms a protective coating that will keep it in good condition for decades. Its high resistance to corrosion makes it particularly suitable for outdoor applications, especially in areas with extreme climatic conditions such as rain, snow or high-salinity air.
Low Maintenance Requirements
Once a protective rust layer has formed, corrugated corten requires little maintenance. Unlike painted steel or aluminium, which need to be repainted periodically to prevent rusting, the natural patina of weathering steel acts as a protective layer without the need for ongoing maintenance. This not only reduces costs, but is also a very practical option for long-term projects.
Environmentally Friendly
Corten corrugated metal is an environmentally friendly material. Its natural rusting process reduces the need for paints and other coatings that can be harmful to the environment. In addition, weathering steel is recyclable, reducing its impact on the environment. It blends well into the natural environment and blends in with the surrounding landscape, making it favoured in sustainable construction.
III. Application Areas of Corten Panels
External wall cladding
Corten steel sheet is used for external wall cladding, which can produce a strong visual impact and make the building stand out in the surrounding environment.
Feature wall
Using weathering steel as feature walls adds texture and layers to the building's exterior design, breaking the monotony of traditional materials.
Roof
Weathering Steel Type A is suitable for roofing applications. Its colour, texture and weatherability make it the perfect choice for projects that seek eye-catching visual effects.
Structural beams and supports
Due to its core strength, weathering steel can also be used for structural applications such as structural beams and supports.
Specific building types
In industrial buildings, it can be used for roofing and external wall cladding in warehouses; in commercial buildings, as architectural panels; in sheds and shops in rural areas; and in well-designed homes, for wall cladding or roofing.
IV.Key Projects Featuring Corten Steel Cladding
Holon Design Museum, Israel
The Holon Design Museum, designed by Ron Arad, is a groundbreaking architectural masterpiece. The exterior of the museum consists of six flowing strips of weathering steel. The strips create a dynamic and visually striking form that stands out in the cityscape. Weathering steel was used to achieve a unique aesthetic effect. The natural rust colour of the steel gives the building warmth and character, and despite being relatively new, it looks as if it has been in the building for a long time. The steel bands not only form the outer shell of the building, but also play a role in defining the interior spaces. As visitors move through the museum, the curves and angles of the steel bands guide the eye and the flow of people, creating a sense of movement. This project demonstrates how corten steel can be used to create highly sculptural and attractive architectural forms.
Dovecote Studios, London, UK
Haworth Tompkin's Dovecote Studio is a small project that demonstrates the creative use of corten steel. The studio is compact, and the use of corten steel in its cladding gives it a distinctive, industrial yet sophisticated look. Over time, the steel cladding of the Dovecote Studios has developed a beautiful patina that complements the surrounding urban environment. Despite its small size, the use of this material makes the studio stand out. The natural rust colour of the corten steel adds warmth and character to an otherwise simple architectural form, contrasting with the more traditional building materials of the area and making the studio a unique and striking part of the London landscape. This project demonstrates that high impact design can be achieved with the use of corten steel in even the most mundane of building projects.
Hackney Back Rooms, London, UK
Hackney Back House is a residential development in a London conservation area. The architects were faced with the challenge of building a new family home within a limited back garden site while respecting the local environment. Weathering steel cladding is part of a carefully selected mix of materials in this project, which also includes ochre brickwork and anodised aluminium windows. The weathered steel box-like structure of the house provides a modern contrast to the existing stone walls on the site. The steel cladding not only gives the house a modern and robust appearance, but will weather gracefully over time, creating a layer of rust that will blend better into its surroundings as the years go by. This project demonstrates how weathering steel can blend into different environments.
Corten steel sidings continue to shine in the architectural arena due to their many benefits. As the trend towards sustainable and unique aesthetics continues, it is believed that weathering steel wall panels will be featured in many more architectural projects in the future, bringing more innovation and surprises to the construction industry.
