Description
ASTM A242 Corten Steel Plate
ASTM A242 Corten Steel Plate is a high-strength, low-alloy structural steel with enhanced atmospheric corrosion resistance. It is designed to form a stable rust-like appearance when exposed to weather, reducing the need for painting and maintenance. This makes it ideal for structural and architectural applications.
- ASTM A242 Type 1 – Commonly used in structural applications due to its excellent strength and corrosion resistance.
- ASTM A242 Type 2 – Less common, primarily used in specific industrial applications requiring enhanced weathering properties.
Key Features:
- Weathering Resistance: Forms a protective oxide layer, preventing further corrosion.
- High Strength: Superior tensile strength for structural applications.
- Low Maintenance: No need for painting, reducing lifecycle costs.
- Aesthetic Appeal: Distinctive rustic appearance for architectural projects.
Dimensions
- Thickness 2–460 mm, 6 mm–200 mm, and 2–500 mm.
- Width 1500–4050 mm, 500–2000 mm, and Up to 4.8 meters.
- Length 3000–15000 mm, 6000–12000 mm, and Up to 12 meters or 40 ft.
