Description
Precision-formed and IS-certified, the Nezone YST 240 350 NB MS CHS (139.7 x 4.5 mm) - 6 mtr Length from Nezone is a cold-rolled ERW CHS in YST 240 structural steel conforming to IS 1161:2014 (Steel Tubes for Structural Purposes). The 139.7 mm OD × 4.5 mm wall circular section (125 mm NB) in 6 m lengths delivers the elevated yield strength suited to demanding columns, frames, and medium-span trusses demanded by medium-duty structural, industrial, and architectural fabrication, with tight wall-thickness tolerance, consistent roundness, and smooth internal bore. The circular form provides equal stiffness in all transverse directions, simplifying connection design and structural analysis for columns, struts, and curved architectural elements.
Key Features:- Grade YST 240 steel: minimum yield strength 240 MPa, tensile strength 360 MPa
- Circular hollow profile 139.7 mm OD × 4.5 mm wall — equal stiffness and bending resistance in all directions
- Uniform wall thickness of 4.5 mm throughout the full 6 m length for consistent performance
- Cold-formed ERW manufacturing ensuring high-integrity, flush weld seam quality
- Conforms to IS 1161:2014 — IS-marked with full batch mill certification
- High strength-to-weight ratio enabling slender, efficient structural sections
- Excellent weldability — compatible with MIG, TIG, SMAW, and orbital welding processes
- Nominal bore 125 mm: compatible with standard flanges, couplings, and threaded fittings
- Square-cut ends for precise measurement and clean joint preparation on site
- Smooth mill-finish external surface suitable for painting, galvanising, or powder coating
- Structural columns, posts, and compression struts in industrial and commercial buildings
- Pre-Engineered Building (PEB) columns, bracing members, and diagonal struts
- Circular truss chord members and web diagonals in roof and bridge trusses
- Handrails, balustrades, stair stringers, and safety guardrail systems
- Gate posts, fencing columns, bollards, and perimeter security structures
- Flagpoles, lighting columns, signage poles, and street furniture supports
- Scaffolding standards, shoring frames, and temporary support structures
