High-strength MS square hollow section in YST 355 from Tata Structura, designed as a cold-formed structural tube for modern steel construction. With a nominal size of 100×100 mm and 6 mm wall thickness in approximately 6 m length, it offers an efficient balance of load-carrying capacity, torsional rigidity and aesthetic appearance for architectural and industrial projects.

The section is manufactured to IS 4923 specifications with stringent control on dimensions, straightness and weld integrity, making it suitable for long-term, low-maintenance structures.

Key Features

• High-strength YST grade with good combination of strength and ductility
• Square hollow profile 100×100 mm providing excellent torsional rigidity and clean visual lines
• Wall thickness around 6 mm for optimised weight and structural efficiency
• Cold-formed, welded hollow section with controlled dimensions and straightness
• Closed box shape offering better resistance to buckling compared to equivalent open sections
• Suitable for welding, bolting and standard fabrication operations

Typical Applications

• Industrial sheds, warehouses and factory buildings
• Architectural columns, frames and space frames
• Trusses, purlins and bracing members
