Champak Steel presents the Champak Steel YST 310 MS SHS - (34 x 34 x 1-2 mm) - 6 mtr Length, a premium ERW Square Hollow Section in YST 310 high-strength mild steel produced to IS 4923:2017 (Hollow Steel Sections for Structural Use). The 34 mm × 34 mm × 1.2 mm symmetrical hollow profile in 6 m lengths combines a guaranteed yield of 310 MPa and tensile of 450 MPa with a clean mill-finish surface for direct deployment in heavy-duty structural, high-load, and long-span applications. The equal-sided geometry eliminates orientation-specific detailing, streamlining fabrication, erection, and connection design on site.

• Minimum yield: 310 MPa | Minimum tensile: 450 MPa — per IS 4923:2017
• Equal-sided hollow section 34 mm × 34 mm with 1.2 mm wall for torsional rigidity
• IS 4923:2017 compliance with IS marking — guaranteed structural quality assurance
• Cold-formed process maintaining tight corner radii for both structural and aesthetic benefit
• Standard 6 m lengths compatible with modular structural grid spacings
• Suitable for hot-dip galvanising, electrostatic powder coating, and intumescent fire protection
• Interchangeable as column, strut, or truss chord — no orientation-specific detailing
• Compatible with standard end plates, fin plates, cleated, and gusset connections
• Prime HR coil input ensuring uniform grain structure and consistent mechanical properties
• Batch-identifiable sections for quality traceability throughout the project lifecycle
