- Architectural Facade Cladding: Corten steel is frequently chosen for exterior facade cladding, providing a modern and industrial look. The rust layer acts as a natural shield, making it a low-maintenance option.
- Landscape Design and Garden Arrangements: With its durable structure and natural aesthetic, Corten steel is used for garden walls, flower beds, pathways, planters, and boundary elements. Its resistance to environmental conditions makes it suitable for outdoor landscape applications.
- Sculpture and Art Installations: Corten steel is a preferred material for sculptures and outdoor art pieces. The gradual color changes and natural aging effect give the artworks a unique appearance over time.
- Bridges and Walkways: Its high corrosion resistance makes Corten steel ideal for bridges, pathways, and overpasses, offering both structural strength and aesthetic appeal.
- Roofing and Downspouts: Corten steel is used in roofing, gutters, and downspouts due to its water-resistant rust layer. Since it self-protects when exposed to water, it is highly durable and long-lasting.
- Commercial and Industrial Buildings: In warehouses, factories, and office buildings, Corten steel is often utilized as a durable, low-maintenance exterior material.
• Alloying Elements: Corten steel contains elements like copper, chromium, nickel, and phosphorus. These elements promote a natural oxidation process (rusting) on the steel's surface, forming a protective layer. This self-protecting layer enhances the material's durability over time.
• Corrosion Resistance: Unlike conventional carbon steels, Corten steel shows high resistance to rust. The thin rust layer, called a patina, prevents further corrosion, making it a long-lasting option for outdoor applications.
• Strength Values: Corten steel typically has higher tensile strength than low-carbon steels. Its tensile strength ranges from approximately 485 to 600 MPa, and its yield strength is about 345 to 460 MPa, offering high durability for structural applications.
• Density: The density of Corten steel is approximately 7.85 g/cm³, similar to that of carbon steels.
• Heat Treatment Properties: Corten steel's durability can be enhanced through heat treatment, and it is well-suited for welding and shaping. These properties make it suitable for complex architectural structures and industrial designs.
• Thermal Expansion Coefficient: The thermal expansion coefficient of Corten steel is around 12 x 10⁻⁶ /°C, which increases its resistance to temperature changes, allowing it to perform well in outdoor and extreme weather conditions.
• Surface Properties: The oxidation (patina) layer that forms over time gives the metal a natural color transition from an orange-brown to a darker brown, creating a unique and organic aesthetic.
