Length 6.0 m +/- 0.05 m Customized length ranging from 6 m to 11 m may be supplied.
Straightness Minimum 1 : 200th of any length measured along the centre line (mill straightened condition) unless
otherwise specifically arranged.
Twist tolerance Maximum 2 mm ± 0.05 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% max, phosphorus content: 0.05% max, equivalent carbon percentage well within specified weldability limits with matching physical properties. For corrosion resistant steel in Cu-bearing variety, refer to the WRS section.
Weldability Tata Structura 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 weight of each bundle is 1.5 Mt (+/-500 kg).
Identification Marking of ‘TATA STRUCTURA’ emblem on surface, punched/stencilled/sticker pasted, on all Steel Hollow Sections. Standard BIS mark is also put on the sections.
Note Tata Structura Hollow Sections in customized size, grade, length, surface finish and end finish may be delivered as per agreed supply conditions.
