The Spark YST 310 MS SHS Spark YST 310 MS SHS - (220 x 220 x 10.0 mm) - 6 mtr Length is manufactured through the ERW cold-forming process to comply with IS 4923:2017, featuring a 220 mm square cross-section with 10.0 mm wall thickness in standard 6 m lengths. With a guaranteed yield strength of 310 MPa and tensile strength of 450 MPa, this hollow section provides reliable mechanical performance for heavy structural columns, high-load bearing frames, and primary structural applications. The biaxially symmetric geometry delivers equal bending resistance on both axes, simplifying structural design and connection detailing in framing and column applications.
