Hot-rolled Q460NH Corten Steel Plate is a high-strength, weather-resistant steel commonly used for structural applications due to its excellent combination of strength, corrosion resistance, and aesthetic appeal.
Dimensional Specifications:
Thickness: 6mm – 60mm (can vary depending on the manufacturer)
Self-Protecting Rust Layer: Q460NH develops a protective patina in response to environmental conditions, which minimizes further corrosion. This makes it suitable for use in outdoor applications without the need for painting or coating.
Advantages of Hot-Rolled Q460NH Plates:
Higher Strength: Q460NH provides higher yield and tensile strength compared to regular steel, making it suitable for load-bearing structures.
Enhanced Corrosion Resistance: The steel’s alloy composition, including copper and chromium, provides it with superior resistance to atmospheric corrosion.
Cost-Effective: Over its lifecycle, it requires less maintenance and upkeep due to its self-protective rust layer.
