Sourced from Champak Steel's certified ERW manufacturing facility, the Champak Steel YST 310 MS RHS - (120 x 40 x 3 mm) - 6 mtr Length is a Rectangular Hollow Section in YST 310 steel built to IS 4923:2017 (Hollow Steel Sections for Structural Use). The 120 mm × 40 mm × 3 mm hollow section in 6 m cut lengths provides superior major-axis stiffness and a tensile strength of 450 MPa, making it the preferred structural element for heavy industrial frames, portal beams, truss chord members, and mezzanine girders. Consistent mechanical properties, clean weld seams, and tight dimensional tolerances ensure reliable integration in welded, bolted, and purlin-clip connections.

• IS 4923:2017 compliant RHS in YST 310 — IS-marked for structural assurance
• Section: 120 mm × 40 mm × 3 mm wall thickness — optimised for spanning and bending applications
• Manufactured via ERW process for strong, consistent weld seam integrity
• High yield strength 310 MPa enables reduced section sizes and lighter structures
• Standard 6 m lengths ready for immediate workshop fabrication or site use
• Excellent formability — cold-bending possible without cracking within standard radii
• Uniform external surface finish for consistency in architecturally exposed structural use
• Compatible with standard end plates, splice connections, and grout-filled column details
• Passes hydrostatic test requirements as per applicable IS norms where specified
• Bundled and clearly labelled by grade and size for easy site identification and handling

• Scaffolding ledgers, horizontal beams, and transom members on construction sites
• Architectural exposed structural beams, pergola cross-members, and screen frames
• Railway platform beam spans, bridge deck members, and footbridge girders
• Water treatment and sewage plant spanning beams and equipment support members
• Airport terminal, shopping mall, and commercial building structural spanning members
• Crane bridge girders, hoist runway beams, and monorail hanging beam sections
• Modular construction floor beams, cassette floor sections, and room module spans
