    Case Study on Stainless Steel Foot Over Bridge in
    Bhayandar Railway Station, Mumbai division, Western Railway, INDIA

    Introduction

    Stainless steel foot over bridges have become essential for pedestrian safety in congested urban areas. In India, where the population density is high, stainless foot over bridges have become a popular solution due to their durability, strength, and resistance to corrosion. This case study examines the benefits and drawbacks of using stainless steel foot over bridges in India, focusing on constructing one such bridge at Bhayandar Railway Station in Mumbai.

    Bhayandar Railway Station

    Bhayandar Railway Station is an important transit hub located in the Mumbai Division of the Western Railway. It serves the rapidly growing residential and commercial hub of Bhayandar in the Thane district of Maharashtra. Its well-connected transport network makes the station crucial for thousands of daily commuters and travellers.

    Stainless steel: optimal for railway station foot over bridges (FOBs)

    Stainless steel is the ideal material for foot over bridges (FOBs) in railway stations in India for several reasons:

    Durability

    Durability: Stainless steel is strong and can withstand harsh weather conditions and heavy foot traffic.

    Corrosion resistance

    Corrosion resistance: Stainless steel is highly resistant to corrosion, even in humid and polluted environments.

    Low maintenance

    Low maintenance: Stainless steel FOBs require little to no upkeep, saving time and money in the long run.

    Aesthetics

    Aesthetics: Stainless steel's sleek and modern appearance enhances the look of railway stations and creates a positive impression for travellers and commuters.

    Cost-effective

    Cost-effective: Stainless Steel is a cost-effective option compared to other materials, despite its long-lasting benefits.

    The stainless steel used in the project

    The Bhayandar foot over bridge project utilized high-quality stainless steel, specifically IRS350CR grade, known for its excellent corrosion resistance and durability. The project used HRAP plates and sheets ranging from 60mm to 40mm thickness applied to the girders, columns, and hollow sections of the bridge. A total of 170 metric tonnes of stainless steel ensures the strength and stability of the bridge for years to come.

    IRS350CR HRAP Plates/Sheets (6mm to 40mm thickness) Griders/Columns/Hollow Sections 170

    Working with Research Designs and Standards Organisation (RDSO) to create a customized grade of stainless steel for bridge application:

    Jindal Stainless set up a war room to solve challenges posed by Indian Railways. The challenges were to find or create the right grade of stainless steel for this application, incorporate this grade into the Policy Manual of RDSO for a pilot study, and finalize specifications and drawings as a benchmark for other bridge constructions. The project used the IRS350CR grade of stainless steel adhering to Design Life and Techno-Economics criteria stated by Indian Railways for bridges with a lifespan of over 100 years.

    Jindal Stainless worked closely with RDSO and other reputed institutes to create and validate the IRS350CR grade of stainless steel for bridge application, ensuring that it met the safety and durability requirements of Indian Railways. The Jindal Stainless team also provided on-ground training and support to the workforce involved in constructing the bridge and developed vendor partners who could supply welding consumables and fasteners that met the project's technical requirements.

    Through these efforts, the Bhayandar foot over bridge project was successfully completed using high-quality stainless steel, ensuring the safety and comfort of thousands of commuters who use the bridge daily.

    Partner Testimonials

    “I am proud to be handling the first stainless steel bridge project in India. It is not only a milestone for Sai projects but for the entire construction industry. In the course of the construction of this bridge, we realized that stainless steel is much easier than we had anticipated initially. Thanks to the hand-holding of Jindal Stainless, our team is much better equipped to manage modern materials and equipment.“

    - Mr Sunil Kodani, Managing Director, Sai Projects

    “The requirement of this stainless steel FOB at Bhayandar Station has been very stringent. Keeping this in mind, we had to customize and process it at our Palghar workshop under the guidance of Jindal Stainless. We abided by the quality procedures mentioned and defined by Jindal Stainless which mainly included storage, handling and fabrication of the girders. Looking at the bridge standing tall today makes me proud and I can easily say all the efforts were worth its while.”

    More details about IRS350CR grade of Stainless Steel

    IRS350CR is a highly prized grade of stainless steel known for its excellent corrosion resistance, durability, toughness, strength, and elasticity. It's a high-chromium, low-nickel austenitic stainless steel that is cost-effective compared to other high-nickel grades. It's non-magnetic, resistant to stress corrosion cracking, and ideal for use in harsh environments where corrosion is a concern. Its high chromium content provides excellent resistance to corrosion and oxidation, while its good mechanical properties make it an ideal choice for girders, columns, and hollow sections. Its cost-effectiveness compared to other high-nickel grades adds to its popularity. With similar chemical composition as shown in below table, Jindal Stainless has also developed IRS450CR with yield strength of 450 MPa, which can result in higher weight savings in infrastructure applications.
