EN10219 Structural Hollow Sections
European norm EN 10219-1 specifies requirements for welded round tubes of unalloyed carbon steel for structural applications. These tubes are available in different thicknesses and are intended for use in the construction of greenhouses, railings and parapets, and general construction.
| 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). |
