The Spark YST 310 Square Hollow Section Spark YST 310 MS SHS - (38 x 38 x 5.0 mm) - 6 mtr Length is cold-formed and ERW-welded to IS 4923:2017 specifications, presenting 38 mm outer dimensions with 5.0 mm wall thickness in standard 6 m lengths. With guaranteed mechanical properties of 310 MPa yield and 450 MPa tensile strength, this SHS serves as a reliable structural component for heavy structural columns, high-load bearing frames, and primary structural applications. The closed square cross-section imparts excellent torsional rigidity and equal bending stiffness on all axes, enabling efficient column and multi-directional frame designs with predictable structural performance.
