Corten Steel
A606 Type 4 weathering steel is a low-alloy atmospheric corrosion-resistant steel designed for sheet and strip applications. It contains alloying elements such as copper, chromium, and nickel, which help form a stable protective rust layer. With good formability, durability, and aesthetic appearance, it is widely used in architectural facades, structural systems, and landscape design projects where both performance and visual effect are required.
Weathering steel (Corten steel) is a low-alloy steel designed for improved atmospheric corrosion resistance. In China, common grades include Q235NH, Q355NH, Q295NH, and Q460NH, while international standards include ASTM A588, EN S355J2W, and others. Through alloy elements such as copper, chromium, and nickel, weathering steel forms a protective rust layer that enhances durability and makes it widely used in construction, bridges, and architectural design applications.
Teda Ganghua is a professional Corten steel supplier and fabricator with over 20 years of experience in steel export and processing. We provide Corten steel plates, coils, and custom fabricated products, including planters, tree grates, and landscape structures. With strong manufacturing capability and stable material supply, we support global customers in architectural, landscaping, and outdoor design projects.
Weathering steel sheet is called “weathering steel” because of its ability to form a protective rust layer that resists environmental corrosion. This unique performance is achieved through its alloy composition and controlled oxidation process.
Corten plates are available in a wide range of thicknesses (3–100 mm), widths (1000–2500 mm), and lengths (up to 12 meters), making them suitable for both architectural and heavy structural applications.
ASTM standards define the core specifications for Corten steel, ensuring consistent quality, performance, and application suitability. Key standards such as ASTM A242, A588, A606, and A847 cover a full range of products from sheets and plates to structural tubing.
Corten steel buildings combine structural strength, corrosion resistance, and unique visual appeal, making them ideal for both architectural and landscaping applications. From building facades to garden structures, Corten steel offers long-term performance with minimal maintenance.
Corten welding is a critical part of a broader set of fabrication processes that include cutting, bending, forming, and surface treatment. With proper control of welding methods, filler materials, and processing parameters, Corten steel can maintain its structural integrity and corrosion resistance.
Corten steel structures are based on the principle of controlled oxidation, where a stable rust layer protects the material instead of degrading it. This unique mechanism allows for long-term durability with minimal maintenance.
Corten steel rolls are supplied in a wide range of thicknesses, widths, and coil sizes, primarily in hot rolled condition. Common grades such as Corten A, Corten B, S355J2W, and Q345NH ensure reliable performance across different industries.
Rusty steel edging made from Corten steel combines engineered alloy composition with a natural rusting process to deliver superior performance. Its key advantages include
Pre-weathered steel is produced through a controlled rusting process that accelerates and stabilizes the natural oxidation of Corten steel. By combining alloy-enhanced corrosion resistance with factory-controlled treatment, it delivers:
A uniform and stable patina
Reduced installation time
Long-term durability
