S355K2W-EN 10025-5 Corten Steel Plate

S355K2W is a high-strength, low-alloy structural weathering steel plate underunder the EN 10025-5 standard. Asstandard. As part of the Corten steel family , it is formulated to deliver excellent resistance to atmospheric corrosion while retaining structural integrity over time. The steel naturally develops a protective oxide layer (patina), reducing the need for painting or coating even in aggressive outdoor environments.

The K2 designation indicates that this grade is tested for impact toughness at -20°C , making it ideal for applications where both corrosion resistance and cold-weather resilience are critical.

Key Features

• 🌧 Outstanding Weather Resistance
  Self-protecting rust layer prevents deeper corrosion and extends service life.

• ❄️ Low-Temperature Impact Performance
  27J impact toughness certified at -20°C, suitable for cold climates and high-altitude installations.

• 🛠 Structural Reliability
  Minimum 355 MPa yield strength, enabling strong and durable load-bearing applications.

• 🧱 Natural Aesthetic
  Forms a warm, rust-like patina perfect for architectural and landscape design.

• ♻️ Low Maintenance
  Eliminates the need for repainting, reducing long-term maintenance costs and environmental footprint.

Applications

• Railway carriages and transport containers

• Highway and pedestrian bridges

• Building facades and corten panels

• Industrial towers and chimneys

• Decorative garden structures and edging

• Wind-resistant infrastructure in cold regions
