CORTEN COIL - CORTEN B

Corten B Steel Coil – High-Strength Weathering Steel for Industrial Use

Conquest Steel & Alloys is a leading supplier of Corten B Steel Coils, which are renowned for their high mechanical strength and superior atmospheric corrosion resistance. Corten B Steel Coils are engineered to withstanding aggressive climatic conditions and are suitable for heavy-duty and structural industrial use.

Corten B, or ASTM A588 Grade B, develops a stable rust-like coating when weathered, providing long-lasting performance without the application of coatings or paint. The steel contains additional alloying ingredients such as copper, nickel, and chromium that improve its corrosion resistance compared to regular carbon steel.

Major Benefits of Corten B Coils:

  • Complies with ASTM A588 Grade B / EN 10025-5 S355J2W specifications
  • Greater tensile and yield strength than Corten A
  • Good weldability, machinability, and formability
  • Better resistance to industrial pollution and adverse weather
  • Specifically suited for bridges, mining machinery, railway wagons, and construction projects

We offer Corten B coils in sizes of custom thickness, width, and coil length with mill test certification and third-party inspection services.
