Home > Hollow Sections > Stainless Steel Hollow Sections
Inox Steel India is a trusted manufacturer and global supplier of Stainless Steel Hollow Sections (SS HS) engineered for architectural, decorative, structural, and corrosion-resistant applications. Available in Square (SHS), Rectangular (RHS), and Circular (CHS) forms, our hollow sections are manufactured as per ASTM A554, ASTM A312, and EN 10296 standards. These products are widely used in environments where long-term durability, premium aesthetics, hygiene, and corrosion resistance are essential—such as architectural infrastructure, marine environments, food processing, pharmaceuticals, railings, façade systems, and design frameworks.
Stainless Steel Hollow Sections are preferred for their smooth finish, excellent mechanical properties, weldability, and resistance to rust, chemicals, humidity, and atmospheric corrosion. With high levels of chromium and nickel, grades such as 304/304L deliver outstanding performance in indoor and moderately corrosive environments, while 316/316L offers superior resistance for coastal, marine, and chloride-heavy applications.
Inox Steel India supplies SS Hollow Sections in sizes ranging from 12×12 mm to 250×250 mm (SHS), 20×10 mm to 300×150 mm (RHS), and 12.7 mm to 508 mm OD (CHS). These sections are available in mirror, satin, brushed, matte, and pickled finish, making them ideal for visible architectural elements and corrosion-critical structures. Our quality-conscious manufacturing process, advanced polishing lines, and certified testing ensure consistent product performance for both domestic and international markets.
With a strong presence across India, the Middle East, Southeast Asia, Europe, and North America, Inox Steel India is a preferred supplier for aesthetic architecture, marine projects, cleanroom applications, and corrosive industrial environments
Stainless Steel Hollow Sections are produced using stringent manufacturing processes to achieve premium surface quality, dimensional accuracy, and corrosion resistance.
This manufacturing sequence ensures premium appearance, high corrosion resistance, and long-term structural stability.
These features make SS Hollow Sections ideal for aesthetic, architectural, hygienic, and corrosive environments.
