Spark presents the Grade YST 240 MS SHS Spark YST 240 MS SHS - (40 x 40 x 2.0 mm) - 6 mtr Length, an IS 4923:2017-compliant ERW cold-formed square hollow section with 40 mm outer dimension, 2.0 mm wall thickness, and 6 m standard length. Certified to achieve a minimum yield of 240 MPa and UTS of 360 MPa, this section is optimised for medium-duty structural framing, industrial supports, and PEB secondary steel requiring equal biaxial strength and precise dimensional accuracy. The square hollow profile enables internal service routing while delivering full structural functionality as columns, posts, and symmetric framing members in steel construction.
