Spark YST 240 Square Hollow Section Spark YST 240 MS SHS - (80 x 80 x 3.2 mm) - 6 mtr Length is produced by ERW cold-forming to IS 4923:2017 with a 80 mm square cross-section and 3.2 mm wall thickness in standard 6 m lengths. Delivering a minimum yield of 240 MPa and tensile strength of 360 MPa, this SHS is engineered for medium-duty structural framing, industrial supports, and PEB secondary steel where equal stiffness on all axes and weld-quality are critical. Its four flat external faces and precise corner geometry simplify connection detailing and allow accurate fit-up in fabricated frames, trusses, and column base assemblies.
