Description
Sourced from AST PIPES's certified ERW tube manufacturing facility, the AST YST 240 20 NB MS CHS - (26.9 x 2.3 mm) - 6 mtr Length is a Circular Hollow Section in YST 240 steel built to IS 1161:2014 (Steel Tubes for Structural Purposes). The 26.9 mm outside diameter × 2.3 mm wall (20 NB) in 6 m cut lengths is a small-diameter circular section suited to handrails, light frames, and secondary structural members providing superior torsional and equal-axis bending performance with a guaranteed tensile of 360 MPa, ideal for industrial frameworks, mezzanine columns, portal frames, and architectural exposed tubes. Consistent roundness, flush weld seam, and tight dimensional tolerances ensure seamless integration with flanges, end plates, and saddle connections throughout.
Key Features:- IS 1161:2014 compliant CHS in YST 240 — IS-marked for certified structural assurance
- Section: 26.9 mm OD × 2.3 mm wall | 20 NB — suitable for structural and mechanical applications
- Manufactured via ERW process for consistent, strong, and flush weld seam integrity
