The RR MetalMakers YST 310 MS RHS - (70 x 30 x 3.6 mm) - 6 mtr Length is a structurally optimised Rectangular Hollow Section from RR MetalMakers, manufactured in YST 310 mild steel to comply with IS 4923:2017 (Hollow Steel Sections for Structural Use). Produced with a 70 mm × 30 mm × 3.6 mm cross-section and 6 m standard cut lengths, this RHS delivers the high yield strength for critical load-bearing structures and reliable ductility required for heavy engineering, crane structures, and high-load frameworks. The ERW process ensures a consistent weld seam, tight ovality, and predictable bending behaviour across each section.

• IS 4923:2017 compliant RHS in YST 310 — IS-marked for structural assurance
• Section dimensions: 70 mm (depth) × 30 mm (width) × 3.6 mm (wall thickness)
• Manufactured via ERW process for a consistent, high-integrity seam weld
• High yield strength 310 MPa minimises section size for lighter structures
• Standard 6 m lengths ready for immediate use on site or workshop fabrication
• Excellent formability — can be cold-bent and shaped without cracking
• Uniform external surface finish for consistent aesthetic in exposed structural applications
• Compatible with standard RHS end plates, splice plates, and gusset connections
• Passes hydrostatic test requirements as per applicable IS norms
• Bundled and clearly labelled for easy site identification and handling

• High-rise building core bracing and perimeter frame members
• Modular construction and containerised building structural components
• Railway station canopies, bus shelters, and platform roofing structures
• Cold storage and refrigerated warehouse structural frames
• Crane boom arms, lifting equipment, and material handling booms
• Airport terminal, mall, and large-span commercial building structures
• Military and defence fabrication: shelters, vehicle parts, and support structures
