Produced to IS 4923:2017 Grade YST 310 via the ERW cold-forming process, the Spark MS SHS Spark YST 310 MS SHS - (113.5 x 113.5 x 4.8 mm) - 6 mtr Length offers a 113.5 mm square cross-section with 4.8 mm wall thickness and 6 m standard length. This hollow section meets a minimum yield of 310 MPa and tensile strength of 450 MPa as required for heavy structural columns, high-load bearing frames, and primary structural applications. The precisely formed square geometry provides maximum torsional efficiency, allowing engineers to design slender yet rigid structural columns and frames with excellent multi-axis load resistance.
