Length 6.0m +/- 0.05 m. Customized length ranging from 6 m to 11 m may be supplied

Straightness Minimum 1:200* of any length measured along the centre line (mill straightened condition) unless otherwise specifically arrnaged

Twist Tolerance Maximum 2 mm +/- mm/m length measured relative vertical shift of any adjacent corner of the section measured by keeping one side on flat surface

End Finish Plain ended – mechanically sheared, mill-cut finish without further machining

Surface Finish/ Chemical properties Black without any surface treatment of oiling or varnishing

Raw Material Sulphur content : 0.05% m ax, Phosphorus content : 0.05% m ax, equiv alent carbon percentage well withinspecied weldability limits with matching physical properties. For corrosion resistant steel in Cu-bearing variety.

Weldability Steel Hollow Sections are weldable with standard M.S, Electrodes without any pre-heating

Packing Bundled by sealing metal strap and each bundle is labelled for size, measurement, lot number etc., Approximate w eight of each bundle is 1.5 Mt (+/- 500kg)

Identification Marking of ‘Manufacturer’ emblem on surface, punched/stenciled/sticker pasted on all Steel Hollow Sections. Standard BIS mark is alos put on the sections.

Note Hollow Sections in customized size, grade, length, surface finish and end finish may be delivered as per agreed supply conditions.

BENEFITS ARCHITECTURAL

Smooth profile of hollow sections is much better than open sections.
Best suited for architecturally exposed steel.
Provides sleek and slender members for skylights and facades maximizing visibility
Easy to bend into various forms and shapes.
Clutter-free fabrication for visually appealing look.

STRUCTURAL

Superior sectional properties allow better use of material, resulting in material savings.
Up to 40% superior compared to conventional angles or channels sections.
Up to 20% superior compared to local steel hollow sections.
High grade steel with better ductility ensures the lighter weight of the structural system.
Encourages the use of long unsupported lengths for columns and beams.
High torsional rigidity.

FABRICATION AND MAINTENANCE

Material savings due to a higher grade (Yst 355) resulting in a lesser cost for fabrication and erection.
Elimination of gusset plates and direct member-to-member connections.
Well-rounded corners that ensure uniform coating thickness.
No dust accumulation, unlike open sections which have exposed internal surfaces
