Description
Nezone YST 310 350 NB MS CHS (193.7 x 4.8 mm) - 6 mtr Length is a cold-formed ERW Circular Hollow Section manufactured from YST 310 mild steel fully conforming to IS 1161:2014 (Steel Tubes for Structural Purposes), delivering a minimum yield strength of 310 MPa and tensile strength of 450 MPa for heavy-duty structural, high-load, and long-span applications. The precise 193.7 mm OD × 4.8 mm wall section (175 mm nominal bore) in 6 m standard lengths provides uniform hoop strength, excellent torsional rigidity, and consistent wall distribution — the hallmarks of heavy engineering, crane columns, high-rise bracing, and long-span truss chords. Produced by Nezone from prime HR coil inputs, each IS-certified tube carries full batch traceability for assured structural and mechanical performance on site.
