Facilities

Tarapur Works — built for the super-heavy

A manufacturing complex engineered around one problem: fabricating equipment too large for anyone else to move.

Manufacturing

Three dedicated fabrication bays

Light fabrication, machining and heavy fabrication run as parallel production lines — so a 110 m column never queues behind a tube bundle.

Bay A

Light Fabrication

22 m wide × 140 m long

Bay B

Machining

20 m wide × 140 m long

Bay C

Heavy Fabrication

27 m wide × 160 m long

Transportation & Logistics

By road up to 250 MT. By water, beyond all limits.

The works has direct access to the Western Express Highway. For equipment that cannot move by road, our own jetty lies just 5 km from the manufacturing complex.

Road Movement

Direct access to the Western Express Highway; dimensions limited by route constraints such as flyovers, sign gantries and high-tension lines.

Max Weight
250 MT
Max OD
6,000 mm
Max Length
48,000 mm

Own Jetty — 5 km

Oversized equipment rolls straight from the works to our captive jetty for waterway dispatch — no road ceiling on diameter or weight.

Distance from Works
5 km
Mode
Barge load-out

Multi-Modal / RO-RO

Waterfront fabrication land in West Bengal enabled direct roll-on/roll-off delivery of mounded bullet sections from Kolkata to Mongla, Bangladesh.
