Features of Corten Steel Wall Cladding:
Corten steel wall cladding offers a range of features and benefits that make it a popular choice for architectural and design applications. Here are some of the features of Corten steel wall cladding:
>> What is Corten Steel Cladding?
Corten steel cladding, also known as weathering steel cladding, is a type of architectural cladding material made from Cor-Ten, a brand of weathering steel. Corten steel is a group of steel alloys that are designed to develop a rust-like appearance when exposed to the weather, creating a protective, durable surface layer. This rust-like patina not only gives Corten steel a distinctive and attractive appearance but also acts as a protective barrier, preventing further corrosion and deterioration of the underlying steel. Here are some key characteristics and uses of Corten steel cladding:
Aesthetic Appeal: Corten steel cladding is valued for its rustic, weathered appearance. The unique patina ranges from deep brown to reddish-brown and evolves with exposure to the elements, creating a visually appealing finish.
Corrosion Resistance: While Corten steel develops surface rust, this rust layer is stable and protects the underlying steel from further corrosion. It eliminates the need for painting or other protective coatings.
Durability: Corten steel is known for its exceptional durability, making it suitable for a range of outdoor applications, including architectural cladding. It can withstand harsh weather conditions and remains structurally sound.
Low Maintenance: One of the advantages of using Corten steel cladding is its low maintenance requirements. It doesn’t need frequent upkeep or repainting.
Architectural Versatility: Corten steel cladding is used in various architectural applications, including wall cladding, building facades, roofing, outdoor sculptures, and decorative elements. Its unique appearance can complement both modern and traditional designs.
>> Equivalent Grade of Corten Steel Cladding
Corten steel is a trademarked name for a group of steel alloys designed to develop a rust-like appearance when exposed to the elements, and it is also known as weathering steel. Equivalent grades of Corten steel cladding, which are essentially similar types of steel that serve the same purpose, can vary depending on the national or international standards used for classification. Here are some equivalent grades of Corten steel cladding in various standards:
ASTM A588: ASTM A588 is often considered an equivalent grade to Corten steel. It is a high-strength, low-alloy structural steel with enhanced atmospheric corrosion resistance. ASTM A588 steel is used for various applications, including building facades, bridges, and outdoor sculptures.
S355JOWP: This is an equivalent grade to Corten steel in the European standard EN 10025-5. It is often used in architectural and structural applications that require weather-resistant properties.
COR-TEN® B: COR-TEN® B is another brand of weathering steel, which is essentially equivalent to Corten steel. It is available in various international standards like JIS (Japanese Industrial Standards) and others.
WR50A: In some regions, you may encounter the designation WR50A, which is another equivalent grade of weathering steel with properties similar to Corten steel.
Fe510C1K1 (UNI): This is an equivalent grade in the UNI (Italian National Standards) system, commonly used in Italy and other European countries.
>> Specifications of Corten Steel Cladding
The specifications for Corten steel cladding can vary depending on the specific requirements of your project and the supplier you are working with. However, here are some common specifications and properties associated with Corten steel cladding:
Material Composition: Corten steel is primarily composed of iron, copper, chromium, and nickel, which are alloyed to create a weather-resistant steel. The exact composition can vary slightly depending on the specific grade and supplier.
Available Grades: Corten steel is available in various grades, including ASTM A588, S355JOWP, COR-TEN® B, and others. The choice of grade depends on the desired properties and specifications for your project.

hickness: Corten steel cladding is available in a range of thicknesses, typically ranging from 1.5mm to 16mm or more. The specific thickness required will depend on the structural and design requirements of your project.
Size and Dimensions: Corten steel cladding can be supplied in various dimensions, including sheets and panels. Common sheet sizes are 2,000mm x 1,000mm or 2,500mm x 1,250mm, but custom dimensions can be fabricated to meet project specifications.
Surface Finish: Corten steel cladding typically has a natural, rust-like surface finish. The steel develops a patina that provides both aesthetic appeal and protection against further corrosion. The specific appearance and development of the patina can vary depending on environmental conditions.
>> Chemical Composition of Corten Steel Cladding
The chemical composition of Corten steel, also known as weathering steel, can vary slightly depending on the specific grade and manufacturer. However, in general, Corten steel is primarily composed of iron, with several alloying elements that give it its distinctive weather-resistant properties. Below is a typical chemical composition for Corten steel:
- Iron (Fe): The primary component, forming the base of Corten steel.
- Copper (Cu): Copper is one of the key alloying elements in Corten steel. It contributes to the material’s weathering properties and helps accelerate the formation of the rust-like patina that protects the steel from further corrosion.
- Chromium (Cr): Chromium is another alloying element that enhances the weathering resistance of Corten steel. It forms a stable oxide layer that contributes to the protective patina.
- Nickel (Ni): Nickel is sometimes present in small quantities in Corten steel. It can further improve the resistance to atmospheric corrosion.
>> Mechanical Properties of Corten Steel Cladding
Corten steel, or weathering steel, is known for its unique mechanical properties, which make it suitable for various architectural and structural applications. The mechanical properties of Corten steel cladding can vary depending on the specific grade and thickness of the material. Here are some common mechanical properties associated with Corten steel:
Tensile Strength: Corten steel typically has a high tensile strength, making it strong and suitable for structural applications. Tensile strength can range from 70,000 to 80,000 psi (480 to 550 MPa) or more, depending on the grade and thickness.
Yield Strength: The yield strength of Corten steel is generally lower than its tensile strength. It typically ranges from 50,000 to 70,000 psi (340 to 480 MPa), depending on the specific grade and thickness.
Elongation: Corten steel usually has a moderate elongation, allowing it to be formed and shaped to some extent. The exact elongation can vary with different grades but is typically in the range of 18-21%.
Modulus of Elasticity (Young’s Modulus): The modulus of elasticity for Corten steel is approximately 200 GPa (29,000 ksi). This property measures the material’s stiffness and its ability to return to its original shape after deformation.
Hardness: The hardness of Corten steel varies with the grade and the processing it has undergone. It can range from relatively soft to harder grades. The Brinell hardness scale (HB) or Rockwell scale (HRC) may be used to measure hardness.
