The Champak Steel YST 310 MS SHS - (25 x 25 x 3 mm) - 6 mtr Length is a structurally certified Square Hollow Section from Champak Steel in YST 310 mild steel, manufactured to the exacting requirements of IS 4923:2017 (Hollow Steel Sections for Structural Use). This 25 mm × 25 mm × 3 mm section in 6 m standard lengths delivers equal performance under axial compression, bending, and torsion — perfectly suited for heavy-duty structural, high-load, and long-span applications. With a minimum yield of 310 MPa and tensile of 450 MPa, it supports efficient structural design with reduced member sizes and optimised material usage.
