Engineered for dependable structural and fluid conveyance performance, the Nezone YST 310 Heavy Duty 20 NB MS Round Pipe - (3.2 x 26.5 mm) - 6 mtr Length by Nezone is a certified Heavy Duty ERW round pipe in YST 310 structural steel aligned with IS 1239:2004 (Mild Steel Tubes, Tubulars, and Other Wrought Steel Fittings). The 26.5 mm × 3.2 mm (20 NB) cross-section in 6 m lengths delivers thicker wall construction for maximum pressure rating and mechanical strength, consistent bore diameter, and reliable suitable for high-pressure fluid conveyance and heavy structural loading — essential for high-pressure pipelines, heavy structural columns, and critical engineering applications. Every section is IS-marked with certified mechanical properties, ensuring design confidence from specification through to site installation.
