At Esha Steel, we proudly supply high-quality ASTM A242 Type 1 Corten Steel Sheets and Plates to industries across Kolkata and nationwide. These sheets and plates are engineered to provide excellent corrosion resistance, durability, and structural strength, making them ideal for outdoor and industrial applications. Manufactured to ASTM standards, Esha Steel ensures precise dimensions, consistent quality, and superior performance. Trusted in construction, infrastructure, and architectural projects, Type 1 Corten steel combines long-term reliability with aesthetic appeal, delivering low-maintenance, weather-resistant solutions for bridges, buildings, facades, and industrial structures.
ASTM A242 Type 1 Corten Steel Sheets and Plates are alloyed with copper, chromium, and nickel, along with controlled carbon, manganese, phosphorus, sulfur, and silicon. This composition enhances corrosion resistance, toughness, and mechanical strength. Mechanically, Type 1 plates provide a minimum tensile strength of 485 MPa and yield strength of 345 MPa, with good elongation and impact resistance. The steel forms a protective patina over time, increasing durability and reducing maintenance needs. Its uniform microstructure allows for reliable welding, fabrication, and forming without compromising mechanical performance or structural integrity.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
ASTM A242 Type 1 Corten Steel Sheets and Plates are widely used in bridges, building facades, outdoor sculptures, industrial structures, and highways due to their exceptional weathering resistance. Their combination of strength and corrosion resistance makes them ideal for architectural projects, structural components, storage tanks, and heavy machinery exposed to outdoor or harsh environments. The naturally forming protective patina eliminates the need for painting or coatings, reducing maintenance costs while offering visual appeal. Engineers and fabricators choose Type 1 Corten steel for long-lasting, durable, and aesthetically pleasing solutions in construction, infrastructure, and decorative industrial applications.
