RR MetalMakers presents the RR MetalMakers YST 310 MS SHS - (200 x 200 x 3.2 mm) - 6 mtr Length, a premium ERW Square Hollow Section in YST 310 mild steel produced to IS 4923:2017 (Hollow Steel Sections for Structural Use). The 200 mm × 200 mm × 3.2 mm symmetrical profile in 6 m lengths combines high yield strength enabling slender sections under heavy axial loads — with a guaranteed yield of 310 MPa and tensile strength of 450 MPa — with a clean mill-finish surface for direct use in heavy-duty structural, high-load, and long-span applications. The equal-sided geometry simplifies design, detailing, and connection fabrication on site.

• Minimum yield strength: 310 MPa | Minimum tensile strength: 450 MPa
• Equal-sided 200 mm × 200 mm hollow section with 3.2 mm wall — optimum torsional rigidity
• IS 4923:2017 compliance with IS marking for guaranteed structural quality
• Cold-formed process maintaining tight corner radii for aesthetic and structural 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 member — 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
