Weathering Steel Corten Steel Sheet 5mm Corten Perforated Sheets Perforated Rust-Resistant Corten Steel Sheet

Products Description

 

Corten Steel, also known as weathering steel, is a high-strength, low-alloy steel that develops a protective, rust-like patina when exposed to weather. This corrosion-resistant layer prevents further deterioration, making it an ideal choice for structures exposed to the elements.

 

Benefits of Corten Steel are as following:

1. Unmatched Durability
Provides superior resistance to atmospheric corrosion, ideal for architectural and industrial structures.

2. Minimal Maintenance
Forms a self-protecting rust layer, eliminating the need for painting and reducing overall maintenance costs.

3. Cost-Efficiency
Higher initial investment but reduced maintenance and longer lifespan make it cost-effective in the long run.

4. Aesthetic Flexibility
Offers a distinctive, evolving appearance that adds rugged character to modern construction.

5. Environmental Sustainability
Longevity means fewer replacements, and its production has less environmental impact compared to other materials.

 

Applications of Corten Steel

  • Corten Steel is incredibly versatile and used across various sectors:
  • Infrastructure: Bridges, guardrails, and railway tracks
  • Architecture: Building facades, roofing, and canopies
  • Industrial: Storage tanks, shipping containers, and silos
  • Landscape Design: Retaining walls, sculptures, and fencing

FAQ

 

Q: Is weathering steel the same as Corten steel?

A: Corten Steel, sometimes referred to as Weathering Steel is a high-strength, low alloy Carbon Steel. Corten Steel was patented in 1933 by the United States Steel Corporation. Typically, it contains 0.2-0.5% copper, 0.5-1.5% chromium, and 0.1-0.2% phosphorus.

 

Q: How long does weathering steel last?

A: Under ideal circumstances, weathering steel can last for decades. In fact, properly designed weathering steel bridges have achieved lifespans up to 120 years with minimal maintenance.

 

Q: How to tell if steel is COR-TEN?

A: Corten Steel undergoes a gradual weathering process so that you may notice signs of ageing, such as rust accumulation and colour changes over time. These visual cues indicate that the steel is indeed Corten and not a standard steel with surface rust.

 

Q: What grade of steel is weathering steel?

A: Weathering steels, such as ASTM A588, A242, A606 and COR-TEN® exhibit superior corrosion resistance over regular carbon steel as a result of the development of a protective oxide film on the metals surface which slows down further corrosion.

 

Q: Can you paint corten steel?

A: Painting Corten steel offers some clear advantages, such as added protection, customization options, and a clean look.
