Corten Steel Plate: What Is It, and Why Is It Called 'Corten'?
Corten steel, or weathering steel, is a distinct type of steel alloy. Corten is mostly for outdoor structures where strength is needed and a unique architectural look is wanted. Part of the appeal of Corten steel is its capacity, when placed outside, to develop a stable rust-like protective layer (often referred to as patina), which when exposed, protects steel from additional atmospheric corrosion. Unlike regular steel, Corten steel does not require further surface treatments, like painting. Corten steel is a highly cost-effective and low maintenance product and is used in demanding applications (from heavy-duty coal wagons made of railroad tracks to architectural designs). The name “Corten” originates from combining its two unique properties; Corrosion resistance and Tensile strength.
What is a Corten Steel Sheet?
Corten steel sheet is also known as weathering steel sheet or Cor-Ten steel sheet, and are well-known for their great ability to weather and beautiful rust coloration. The protective patina produced by this self-weathering steel alloy will increase durability and do away with the need for painting. Perfect for architectural and structural applications that require a combination of both strength and beauty.
What Indian Standard Governs Corten Steel Plates?
For applications within Indian Railways, the prevalent standard for Corten steel plates is IRSM 41-97. Corten Steel Tube ensures its Corten products can meet such stringent requirements.

Corten Steel Sheet: Is It Expensive? Understanding Why and Its Price in India.
Generally, Corten steel sheets command a higher price point compared to standard carbon steel sheets. Several factors contribute to the cost of Corten steel sheets:
- Alloying Elements & Manufacturing: The specific chemical composition, including elements like copper, chromium, nickel, and phosphorus, along with the specialized manufacturing process, adds to the base cost.
- Superior Mechanical Properties: The enhanced tensile strength and corrosion resistance offered by Cor-ten steel sheets provide long-term value, justifying the initial investment.
- Aesthetic Appeal & Demand: The unique, evolving rusty appearance is highly sought after in modern architecture and landscaping, driving demand.
- Market Variables: The price of Corten steel plates from suppliers like Corten Steel Tube can fluctuate based on:
- Our internal production and procurement costs.
- Prevailing market conditions for raw materials.
- The volume of your order.
- Any custom cutting, forming, or finishing requirements.
- Logistics and delivery location within India or internationally.

- Low Maintenance: Saves time and resources on upkeep.
- Sustainability: Corten steel is an environmentally friendly and recyclable material.
The longevity of Corten roof sheets from Corten Steel Tube is influenced by environmental factors (humidity, salinity, pollutants), maintenance efforts, and the sheet’s thickness. Corten steel is known for its excellent long-term performance, often outlasting other roofing materials. On average, you can expect Corten roof sheets to last anywhere from 30 to 50 years, or even longer, especially under favorable conditions and with appropriate design considerations.
Corten steel is typically more expensive than regular carbon steel due to its unique properties like corrosion resistance and aesthetic appeal. However, it is cost-effective in the long term because it eliminates the need for painting or coating, reducing maintenance costs. Corten Steel Tube offers competitively priced Corten steel sheets and plates with premium quality and durability.
A Corten steel sheet is a weathering steel designed to develop a protective rust layer (patina) when exposed to atmospheric conditions. This patina enhances corrosion resistance, making it ideal for outdoor applications like architectural facades, garden designs, and roofing. Corten Steel Tube supplies high-quality Corten steel sheets in various grades, thicknesses, and custom sizes.
While Corten steel is highly durable and corrosion-resistant, it can be prone to rusting in environments with constant water exposure or high humidity, such as marine areas. Additionally, improper drainage can lead to water pooling, accelerating corrosion. At Corten Steel Tube, we provide expert guidance on using Corten steel effectively to maximize its lifespan.
A 2mm Corten steel sheet can last anywhere from 30 to 50 years, depending on environmental factors and maintenance. Its lifespan is extended in dry climates where the patina forms evenly. Corten Steel Tube ensures the highest-quality Corten steel sheets to withstand diverse conditions and provide long-lasting performance.
