Description
Combining equal-axis strength with precision circular geometry, the AST YST 210 80 NB MS CHS - (88.9 x 4.8 mm) - 6 mtr Length from AST PIPES is a cold-formed ERW CHS in YST 210 structural steel conforming to IS 1161:2014 (Steel Tubes for Structural Purposes). The 88.9 mm OD × 4.8 mm wall (80 NB) section in 6 m lengths is a medium-diameter circular section ideal for columns, struts, and architectural structural elements achieving an optimal balance of axial capacity, torsional resistance, and fabrication ease for general construction, light framing, handrails, and utility support structures. With minimum yield of 210 MPa and tensile of 330 MPa, this IS-certified tube meets the performance demands of light-to-medium structural, architectural, and utility applications with full traceability.
Key Features:- Certified YST 210 ERW CHS meeting all structural requirements of IS 1161:2014
- Precise 88.9 mm OD with 4.8 mm wall: consistent roundness and flush seam throughout
- Wall thickness 4.8 mm maintained within tight IS tolerances along the full 6 m length
- Consistent ERW weld quality: clean, flush seam on both internal and external surfaces
