Spark presents the Grade YST 240 MS RHS Spark YST 240 MS RHS - (200 x 150 x 8 mm) - 6 mtr Length, an IS 4923:2017-compliant ERW cold-formed rectangular hollow section with 200 mm depth, 150 mm width, 8 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 directional bending strength and dimensional accuracy. The rectangular hollow profile allows internal service routing while delivering full structural functionality as beams, lintels, and spanning members in steel construction.

• Cold-formed ERW rectangular hollow section to IS 4923:2017 Grade YST 240
• Four flat external faces providing maximum bearing area for connection hardware
• Minimum 240 MPa yield and 360 MPa UTS meeting structural design code requirements
• Precise rectangular geometry enabling flush-face connections without packing plates
