Description
The AST YST 210 20 NB MS CHS - (26.9 x 3.2 mm) - 6 mtr Length manufactured by AST PIPES is a prime-grade ERW Circular Hollow Section in YST 210 mild steel aligned with IS 1161:2014 (Steel Tubes for Structural Purposes). Offering a 26.9 mm OD × 3.2 mm wall profile (20 NB) in 6 m standard lengths, this CHS is a small-diameter circular section suited to handrails, light frames, and secondary structural members delivering minimum yield of 210 MPa, excellent ductility, and a smooth external finish — making it a preferred structural and architectural tube for light-to-medium structural, architectural, and utility applications. The circular profile's inherent torsional efficiency and equal bending capacity make it a go-to section for exposed structural columns and architectural applications.
Key Features:- Minimum yield: 210 MPa | Minimum tensile: 330 MPa — as per IS 1161:2014
- Circular cross-section 26.9 mm OD with 3.2 mm wall: cost-effective strength for everyday structural and plumbing service
- IS 1161:2014 compliance with IS marking — guaranteed structural quality assurance
- Cold-formed process for tight dimensional tolerances and superior roundness control
- Standard 6 m lengths compatible with modular structural and architectural grid spacings
- Suitable for hot-dip galvanising, electrostatic powder coating, and intumescent fire treatment
- Equal bending resistance in all planes — no orientation-specific design or detailing required
- Compatible with standard weld-on flanges, end caps, saddle clamps, and rosette connections
- Prime HR coil input ensuring uniform grain structure and consistent mechanical properties
- Batch-identifiable tubes for quality traceability throughout the project lifecycle
- Industrial plant pipe racks, equipment skid frames, and reactor support structures
- Mining equipment frames, conveyor gantry columns, and ore-handling structure legs
- Crane runway columns, gantry uprights, and jib crane mast sections
- Shipbuilding and marine structural tubulars for hull and above-deck structures
- Overhead electrical transmission tower leg members and bracing tubulars
- Workshop jigs, fixture frames, and custom fabrication support structures
- Cold-storage and refrigerated warehouse structural frames and column supports
