High-strength MS rectangular hollow section in YST 355 from Tata Structura, designed as a cold-formed structural tube for modern construction and fabrication. With a nominal size of 50×25 mm and 4 mm wall thickness in about 6 m length, it offers excellent load-carrying efficiency, superior torsional rigidity and clean architectural lines compared to conventional open sections.

The section is manufactured to IS 4923 or equivalent hollow section standards with tight control on dimensions, straightness and weld integrity, delivering dependable performance in long-span and repetitive structural applications.

Key Features
