ASTM A606 Type 4 Corten Hollow Section Supplier – Conquest Steel & Alloys
Conquest Steel & Alloys is a leading ASTM A606 Type 4 corten hollow section manufacturer, providing hollow steel sections in square (SHS), rectangular (RHS), and round (CHS) shape. The ASTM A606 Type 4 weathering steel has an added amount of copper and phosphorus content for increased corrosion resistance and patina development—making it suitable for highly exposed structural and architectural applications where aesthetics and low maintenance are essential.
Our ASTM A606 Type 4 corten hollow sections vary from 20 mm to 300 mm in outer size with wall thicknesses of 2 mm to 25 mm. The grade has yield strengths of ≥355 MPa with high weldability, formability, and rigidity. For structural frames, outdoor architectural features, bridge fittings, signposts, and landscape fixtures, they provide durability and aesthetic value.
All sections are backed by ASTM A606 Type 4 mill test certificates to meet mechanical and chemical demands (specifically increased copper content for better development of patina). Conquest Steel & Alloys also offers precision cutting, beveling, notching, end-prepping, and optional pre-weathered surface finishes to simplify project delivery and installation.
Being a committed ASTM A606 Type 4 corten hollow section stockist, we provide high-quality, certified, and corrosion-resistant hollow sections—supported by technical assistance and logistics for structural and architectural applications requiring durability and design superiority.
