India’s public sector steel giant SAIL emerges as the largest supplier for the strategically vital Zojila Tunnel, delivering over 31,000 tonnes of high-grade steel to support all-weather Himalayan connectivity and national security.
New Delhi (Economy India): India’s leading public sector steel producer, Steel Authority of Steel Authority of India Limited (SAIL), has cemented its position as a key player in India’s infrastructure development by supplying more than 31,000 tonnes of steel for the Zojila Tunnel Project.

Key Highlights:
- 🚧 SAIL is the largest steel supplier for the Zojila Tunnel.
- 🏗️ Supplied over 31,000 tonnes of TMT rebars, structural steel, and steel plates.
- 🛣️ Zojila Tunnel to be India’s longest road tunnel (30+ km), Asia’s longest bi-directional tunnel.
- 🌨️ Will ensure all-weather connectivity between Srinagar and Leh.
- 🇮🇳 Boosts strategic and military logistics in high-altitude zones.
- 🔩 SAIL’s steel was also used in the Chenab Bridge, Atal Tunnel, and Bandra-Worli Sea Link.
A Backbone for Nation-Building
SAIL has played a strategic role in India’s high-priority infrastructure projects, and its contribution to the Zojila Tunnel underlines its reliability as a national asset. The project is part of the government’s broader National Infrastructure Pipeline (NIP) and will strengthen border connectivity in the sensitive Himalayan belt.
The Magnitude of the Project
Located at an altitude of 11,578 feet, the Zojila Tunnel is being constructed in challenging Himalayan terrain and spans over 30 kilometers. Once completed, it will provide uninterrupted year-round road access between Srinagar and Leh, passing through the key regions of Dras and Kargil.

Steel That Binds Mountains
SAIL has supplied a wide range of products including:
- ✅ TMT rebars – to reinforce tunnel walls and lining structures.
- ✅ Structural steel – for tunnel frames and support systems.
- ✅ Steel plates – for load-bearing sections and seismic protection.
This steel has been engineered to withstand extreme weather, seismic activity, and intense load-bearing conditions.
Supporting Military and Civilian Movement
The Zojila Tunnel will dramatically improve mobility for both armed forces and civilians in Jammu & Kashmir and Ladakh, reducing travel time and operational risk during snowbound months. It’s expected to act as a logistics corridor for strategic deployment in sensitive border regions.
Completion Timeline and Continuity of Supply
The project is targeted for completion by 2027, and SAIL continues to supply materials in a phased and timely manner, showcasing its efficiency in handling mega-scale demands.
Economic & Social Impact
- 📈 Promotes regional economic development.
- 🧱 Boosts employment in remote districts.
- 💼 Encourages private investment and trade in border areas.
- 🏨 Improves access to healthcare, tourism, and education.
Trust Forged in Steel
Mega projects like Zojila place enormous trust on material quality. SAIL’s consistency in quality assurance, on-time delivery, and engineering excellence make it a natural choice for such high-impact ventures.
Legacy of Engineering Marvels
SAIL’s involvement in Zojila Tunnel continues its legacy of supporting iconic Indian infrastructure projects, including:
- Chenab Railway Bridge
- Atal Tunnel (Rohtang)
- Bandra-Worli Sea Link
- Bogibeel and Dhola-Sadiya Bridges
Aligning with Atmanirbhar Bharat
As India moves towards self-reliance in infrastructure, SAIL’s indigenous steel production ensures that global-grade quality is available within the country – reducing dependency on imports and cutting costs.
SAIL’s Vision: Infrastructure with Integrity
Speaking on the development, a SAIL spokesperson stated:
“Our mission is not just to supply steel but to strengthen India’s future. Zojila Tunnel is a perfect example of how Indian steel is shaping Indian destiny.”
What Lies Ahead
Once operational, the tunnel is expected to:
- Cut travel time between Srinagar and Leh by hours.
- Ensure all-weather transport, especially during snow seasons.
- Provide alternate emergency routes.
- Reduce reliance on air transport during disruptions.
Steel of the Nation
With more than 31,000 tonnes of steel already supplied and more on the way, SAIL’s role in the Zojila Tunnel is more than just supply—it’s about shaping India’s connectivity, security, and economic potential.
