Corten Steel I-Beam

Corten Steel I-Beam is a weather-resistant structural steel product shaped like the letter “I”, specifically designed for construction and engineering projects that require high strength and enhanced corrosion resistance. Manufactured from atmospheric corrosion-resistant steel, such as ASTM A588, EN 10025-5, or JIS G3114 grades, it forms a stable rust-like patina on the surface that eliminates the need for painting or surface coating in most outdoor environments.

Ideal for medium-duty structural applications, Corten I-Beams provide excellent mechanical performance while minimizing maintenance costs over time.

🔹 Key Features

• Excellent resistance to atmospheric corrosion

• Self-healing rust layer reduces maintenance

• High strength-to-weight ratio

• Lighter than H-Beam for similar spans

• Cost-effective for medium structural applications

• Compatible with welding, cutting, drilling, and bolting

🔹 Available Standards & Grades

🔹 Typical Mechanical Properties (ASTM A588 Grade B as Example)

🔹 H-Beam vs I-Beam – Key Differences

👉 Choose I-Beam when your structure needs lightweight, efficient performance under vertical loads, with high weathering resistance.

🔹 Applications
