MS square hollow section in YST 355 from Jindal Hissar, produced as a cold-formed structural tube for versatile use in infrastructure, fabrication and industrial frameworks. The 150×150 mm size with 4 mm wall thickness and around 6 m stock length provides a robust yet economical solution wherever closed box sections are preferred over open sections.

The tube is made from high-quality steel with consistent weld quality and section geometry, helping fabricators achieve accurate fit-up and reliable performance in service.
