Combining spanning efficiency with precision dimensional accuracy, the Champak Steel YST 310 MS RHS - (120 x 40 x 4 mm) - 6 mtr Length from Champak Steel is a cold-formed ERW RHS in YST 310 structural steel conforming to IS 4923:2017 (Hollow Steel Sections for Structural Use). The 120 mm × 40 mm × 4 mm cross-section in 6 m lengths achieves an optimal balance of major-axis bending capacity, torsional resistance, and fabrication ease for heavy industrial frames, portal beams, truss chord members, and mezzanine girders. With minimum yield of 310 MPa and tensile of 450 MPa, this RHS meets the demands of heavy-duty structural, high-load, and long-span applications with traceable, certified quality.
