📄 Product Description: Indaten® Weathering Steel — Structural Steel with Natural Corrosion Resistance
🧾 General Technical Characteristics
Indaten® is a brand of weathering steel (also known as COR-TEN steel), developed and manufactured by ArcelorMittal. Unlike standard carbon steels, Indaten® forms a dense oxide film — patina — on its surface, which protects the metal from further atmospheric corrosion.
The patina develops naturally when exposed to moisture and oxygen, creating a decorative rust-like appearance that also serves as a protective layer. This eliminates the need for additional painting or coating.
⚙️ Applications
- Architectural facades and cladding
- Bridges, pedestrian crossings, and waterfront structures
- Park furniture and outdoor equipment
- Art installations and sculptures
- Noise barriers and retaining walls
- Technical and transport infrastructure
📈 Advantages
- ✅ High resistance to atmospheric corrosion without painting
- ✅ Develops a decorative patina over time
- ✅ Reduced maintenance and painting costs
- ✅ Eco-friendly and resistant to environmental factors
- ✅ Aesthetic appearance without additional treatment
🧪 Mechanical Properties (example: Indaten® S355W)
- Yield strength: ≥ 355 MPa
- Tensile strength: 470–630 MPa
