At Esha Steel, we proudly supply premium ASTM A606 Type 4 Corten Steel Sheets and Plates to industries across Kolkata and nationwide. Engineered to provide exceptional atmospheric corrosion resistance, these sheets and plates are designed for long-term durability in structural and architectural applications. Manufactured to ASTM standards, Esha Steel ensures precise dimensions, consistent quality, and superior mechanical performance. Trusted in construction, infrastructure, and industrial sectors, Type 4 Corten steel combines strength, low-maintenance weathering, and aesthetic appeal, delivering reliable solutions for bridges, building facades, and outdoor structures exposed to harsh environments.
ASTM A606 Type 4 Corten Steel Sheets and Plates are alloyed with copper, chromium, and nickel, alongside controlled carbon, manganese, phosphorus, sulfur, and silicon content. This composition enhances corrosion resistance, toughness, and mechanical strength. Mechanically, the plates provide a minimum tensile strength of 485 MPa and yield strength of 345 MPa, with good elongation and impact resistance. Over time, the steel forms a protective rust-like patina, improving durability in outdoor and industrial applications. Its uniform microstructure allows for reliable welding, fabrication, and forming without compromising 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 A606 Type 4 Corten Steel Sheets and Plates are widely used in bridges, highways, architectural façades, industrial structures, and outdoor sculptures where long-term weathering resistance is critical. Their combination of high strength and corrosion resistance makes them suitable for building cladding, structural supports, storage tanks, and machinery components exposed to outdoor environments. The naturally forming protective patina reduces maintenance requirements while enhancing aesthetic appeal. Engineers and fabricators choose Type 4 Corten steel for projects that demand both structural reliability and visual appeal, ensuring durable, safe, and low-maintenance performance in harsh weather and industrial conditions.
