SAIL becomes the first Indian steel maker to roll NPB – 750

16 October 2018

Continuing its efforts to strengthen country’s infrastructure and provide cost effective solutions to construction sector, Steel Authority of India Ltd. (SAIL) has become the first domestic steel maker to successfully roll NPB–750 (NPP-750) Narrow Parallel Flange Beams. The depth of NPB-750 will be 750 millimetre with three different sectional weights as per the standards of BIS. NPB–750 has been successfully rolled by the new and state-of-the-art Universal Structural Mill (USM) of SAIL’s IISCO Steel Plant.

Beams with more depth, like in case of NPB–750, have higher load bearing capacity, which makes the construction more cost effective and saves time at the same time. NPB–750 can be used in infrastructure projects such as bridges, flyovers, railway bridges, frames for various factories, multi stories etc. The load bearing capacity of a narrow parallel flange beam is directly proportional to the depth of the beam. So, NPB–750 can provide better solutions for the construction projects in both private and public sectors.

In India, NPB in maximum 600 mm depth either rolled or ready was available so far. To fulfil requirements of NPB with more depth, it had to be fabricated, which resulted in wastage and increase in input cost.  Apart from being cost effective and time efficient, NPB–750 will also provide more strength to the construction.

Production of Structurals from USM started in May, 2017. Since then various Structurals have been added to SAIL’s product basket. The parallel flange beams of IISCO Steel Plant are certified under BIS: IS 12778 standards.

SAIL Structurals are better in many ways than conventional concrete constructions because they are helpful in erecting both light and heavy structures/frames, they are easier in fabrication, they reduce the time of construction, and they allow inclusion of more aesthetic elements. Also, with improved life cycle cost using these structurals, the need to re-invest in the project repeatedly also reduces. Owing to the strong properties of these Structurals, they are better placed to absorb effects of earthquake. Structurals also allow the replacement of a part of the structure during any maintenance thus reducing inconvenience. Due to these properties, today such steel products are being used in every nation’s most modern projects.

SAIL Chairman Shri Anil Kumar Chaudhary has lauded this achievement of IISCO Steel Plant and said “SAIL is continually developing high quality products suited to the requirements of the nation and the market. To fulfil these requirements we are not only working on production front but also focussing equally on the marketing aspect.”

To popularize and give impetus to the use of SAIL Structurals, the Company   has also undertaken a campaign NEX From SAIL – The Future in Steel Design and has launched these in market under the brand name of NEX From SAIL. NPB–750 is the new product in the NEX series, which will not only provide strength to the construction but will also prove to be cost effective.
