Description
Champak Steel YST 310 MS RHS - (80 x 40 x 5 mm) - 6 mtr Length is a cold-formed ERW Rectangular Hollow Section manufactured from YST 310 high-strength mild steel fully conforming to IS 4923:2017 (Hollow Steel Sections for Structural Use), delivering a minimum yield strength of 310 MPa and tensile of 450 MPa for heavy-duty structural, high-load, and long-span applications. The precise 80 mm × 40 mm × 5 mm asymmetric cross-section across 6 m standard lengths provides superior bending resistance in the major axis, making it ideal for heavy industrial frames, portal beams, truss chord members, and mezzanine girders. Produced by Champak Steel from prime HR coil, each IS-certified section offers full batch traceability and consistent mechanical properties throughout.
