MS rectangular hollow section in YST 355 from Jindal Hissar, produced as a cold-formed structural tube for versatile use in industrial, infrastructure and commercial projects. The 66×33 mm outside dimensions with 4.5 mm wall thickness and approximately 6 m stock length provide a robust yet economical box section where rectangular profiles are preferred for orientation and cladding requirements.

Consistently rolled and welded from quality steel, the section offers reliable mechanical properties and uniform geometry that simplify fabrication and erection at site.

Key Features

• High-strength YST grade providing a good balance of strength and ductility
• Rectangular hollow profile 66×33 mm for efficient use in oriented framing and architectural members
• Wall thickness around 4.5 mm optimised for strength-to-weight performance
• Cold-formed, welded tube with controlled dimensions, straightness and corner radii
• Closed box shape with better resistance to buckling and torsion than comparable open sections
• Suitable for welding, bolting, cutting and standard fabrication processes

Typical Applications

• Columns, rafters and portal frames in industrial and warehouse buildings
• Beams, lintels and edge members in commercial and institutional structures
• Space frames, canopies and façade support systems
• Railing, handrail and boundary frameworks
• Support structures for solar plants, signage and utility platforms
