MS ERW Rectangular Hollow Section Price Today

MS ERW (Electric Resistance Welded) rectangular hollow sections (RHS) are structural steel tubes with a rectangular cross-section, manufactured by forming HR steel coils into tubular shape and welding the seam using high-frequency electric resistance welding. RHS profiles are one of the most versatile structural steel products, combining high strength-to-weight ratio with clean aesthetics.

India's structural steel tube industry has seen explosive growth, led by APL Apollo Tubes which has become the world's largest structural steel tube manufacturer with capacity exceeding 6 MTPA. Other major producers include Jindal (India), Tata Steel (Tata Structura), Hi-Tech Pipes, and Surya Roshni. The shift from conventional angle/channel construction to hollow section-based construction is driving rapid market growth.

RHS pricing follows HR coil rates plus a conversion premium that covers forming, welding, sizing, testing, and finishing. OfBusiness provides builders, fabricators, and infrastructure companies with competitive RHS pricing from leading brands with full test certification and flexible delivery options.

MS ERW rectangular hollow sections are manufactured to exacting standards:

• IS 4923: Hollow steel sections for structural use. Grades: YSt 210, YSt 240, YSt 310 (yield strength in MPa). This is the primary standard for structural RHS in India.
• IS 1161: Steel tubes for general engineering purposes. Suitable for non-structural applications.
• ASTM A500: International standard for cold-formed welded structural hollow sections. Grades B and C.
• EN 10219: European standard for cold-formed welded structural hollow sections. Grades S235, S275, S355.

Size range: 20x10 mm to 300x200 mm | Thickness: 1.6 mm to 8.0 mm | Length: Standard 6 m (custom lengths available) | Surface: Black (mill finish), galvanized, or pre-painted.

Testing: Hydraulic test (as per IS 1239), flattening test, drift test, bend test, tensile test. All products supplied with mill test certificates covering chemical composition and mechanical properties. ERW weld seam is subjected to online eddy current or ultrasonic testing for weld integrity.
