The Spark YST 240 MS SHS Spark YST 240 MS SHS - (50 x 50 x 2.0 mm) - 6 mtr Length is manufactured through the ERW cold-forming process to comply with IS 4923:2017, featuring a 50 mm square cross-section with 2.0 mm wall thickness in standard 6 m lengths. With a guaranteed yield strength of 240 MPa and tensile strength of 360 MPa, this hollow section provides reliable mechanical performance for medium-duty structural framing, industrial supports, and PEB secondary steel. The biaxially symmetric geometry delivers equal bending resistance on both axes, simplifying structural design and connection detailing in framing and column applications.
