High-strength MS circular hollow section in YST 210 from Tata Structura, designed as a cold-formed structural tube for modern steel construction, fabrication and general engineering. The 20 NB size with 26.9 mm outside diameter and 2.6 mm wall thickness in approximately 6 m stock length offers an efficient closed section for axial, bending and torsional load conditions.

Manufactured to IS 1161:2014 or equivalent hollow section standards with stringent control on ovality, straightness and weld quality, these circular tubes deliver reliable performance in repetitive and long-span applications.

Key Features

• High-strength YST 210 grade with good combination of strength and ductility
• Nominal 20 NB circular hollow section with about 26.9 mm outside diameter for uniform load distribution
• Wall thickness around 2.6 mm optimised for strength-to-weight efficiency
• Cold-formed, welded tube with controlled ovality, straightness and corner profile at weld
• Closed hollow shape offering better torsional rigidity and buckling resistance than comparable open sections
• Suitable for welding, bolting, bending, cutting and standard fabrication operations

Typical Applications

• Columns, trusses and bracing members in industrial and commercial buildings
• Architectural features, handrails and aesthetic tubular frameworks
• Transmission towers, poles and mast structures
• Support structures for solar, signage and utility installations
• General engineering, furniture and gym equipment fabrication
