Description
AST PIPES's AST YST 240 15 NB MS CHS - (21.3 x 2.6 mm) - 6 mtr Length is a high-quality cold-formed ERW Circular Hollow Section in YST 240 structural steel produced to IS 1161:2014 (Steel Tubes for Structural Purposes). The 21.3 mm OD × 2.6 mm wall (15 NB) hollow circular cross-section in 6 m lengths is a small-diameter circular section suited to handrails, light frames, and secondary structural members engineered for outstanding weldability, superior torsional resistance, and elevated yield strength for demanding structural columns and medium-span trusses — all essential for industrial frameworks, mezzanine columns, portal frames, and architectural exposed tubes. Processed from prime HR coil through precision roll-forming and ERW welding, each tube delivers dimensional consistency, certified mechanical properties, and a smooth internal bore throughout.
