Corten steel sheet

Corten Steel Sheet Information

Our natural Corten steel sheet is a durable and versatile material, renowned for its unique weathering properties and rich, evolving patina. Fabricated like ordinary mild steel, Corten steel is enhanced with alloying elements including copper, chromium, nickel, and phosphorus, which give it its characteristic corrosion resistance and aesthetic appeal.

What is Corten Steel?
Corten steel, also known as weathering steel, is designed to form a stable rust-like surface over time. Unlike standard mild steel, which corrodes continuously until perforation, Corten’s rust layer forms a protective barrier that prevents further corrosion. This self-protecting property makes it ideal for outdoor use, offering both durability and a distinctive appearance. COR-TEN is a registered trademark of U.S. Steel and one of many weathering steels available globally.

Weathering Properties:
Corten steel develops its rust layer through natural wet and dry cycles. When left exposed to the elements, the surface transforms from a bright, lightly oiled appearance to a vivid orange patina, eventually maturing into a deep chestnut-brown hue. This natural process makes Corten steel a favourite for architectural, landscaping, and artistic applications.

Rusting and Patina Development:
To encourage natural patina formation, simply wash the sheet to remove any grease and leave it outdoors. Exposure to rain, wind, and sunlight will gradually develop the protective rust layer, ensuring both functionality and aesthetic appeal. Over time, the patina adds character and a timeless quality to the steel.

Lacquering Options:
For indoor use or to preserve the appearance of the patina, the steel can be treated with a clear lacquer. This process seals the surface, preventing rust transfer and enhancing the finish. Ensure the surface is dry, smooth, and free of dust before applying lacquer for optimal results.

Applications of Corten Steel Sheet:
Corten steel sheet is ideal for a variety of applications, including:

• Architectural Features: Facades, cladding, and structural elements with a weathered look.
• Landscaping: Planters, retaining walls, and garden accents.
• Sculpture and Art: Adds an industrial yet natural touch to creative projects.
• Interior Design: Decorative panels, fireplace surrounds, and furniture with a rustic appeal.

Additional Notes:
Corten steel’s evolving appearance and inherent durability make it a popular choice for projects where aesthetics and longevity are equally important. Its ability to resist further corrosion without maintenance ensures it remains a sustainable and cost-effective material for outdoor and indoor applications.
