Produced to IS 1161:2014 Grade YST 240 by the ERW manufacturing process, the Hi-Tech Pipes MS CHS Hi-Tech YST 240 25 NB MS CHS (33.7 x 1.6 mm) - 6 mtr Length offers a 33.7 mm outer diameter, 25 NB nominal bore, and 1.6 mm wall thickness in standard 6 m lengths. This circular hollow section meets minimum yield of 240 MPa and tensile strength of 360 MPa for reliable use in general structural framing, furniture, light industrial supports, and ERW pipe applications. The round closed profile eliminates stress concentration at corners and provides a consistent section modulus in all planes, making this tube an efficient and aesthetically preferred choice for structural columns and exposed steel frames.
