Railway OHE Structures & Steel Channel Sleepers | RDSO

Name: Railway OHE Structures & Steel Channel Sleepers
Brand: Indo East Corporation

Indo East manufactures steel channel sleepers and overhead equipment structures for Indian Railways, to RDSO approved drawings and Railway Board specifications, and has done so continuously since 2001. Sleepers are held to ±0.5 mm across thousands of identical pieces, robotically welded, and dimensionally inspected before galvanizing.

Worth saying plainly to an overseas reader: RDSO approval is an approval of Indian Railways and carries no weight with another country's rail authority. The fabrication capability travels; the approval does not.

Railway OHE & Electrification Structures

Indo East Corporation manufactures Overhead Electrification (OHE) masts, portal structures, and gantries for Indian Railways electrification projects. Our structures are built to RDSO approved specifications and are supplied to major EPC contractors involved in Indian Railways' 100% electrification mission.

Railway structures demand extreme precision and repeatability — requirements we meet through CNC plasma cutting, robotic welding, and stringent dimensional inspection prior to galvanizing.

Everything for Indian Railways

The whole railway range, in one place

Structures, sleepers, towers and fittings — all of it fabricated and hot-dip galvanized on one floor at Jangalpur, Howrah. That is why the coating on the fitting matches the coating on the mast it bolts to, and why the fabrication record and the coating record come from the same works and the same set of documents. Indo East is RDSO approved for railway structures.

Railway Structure FAQ

Frequently Asked Questions

What railway structures does Indo East manufacture?

Overhead electrification (OHE) masts, portal structures, registration and cantilever arms, stay sets, overlap structures and gantries, plus steel channel sleepers for Indian Railways.

Is Indo East an RDSO approved manufacturer?

Yes. Indo East Corporation is an RDSO approved manufacturer. Railway structures and steel channel sleepers are made to RDSO approved drawings and Railway Board specifications.

Which traction systems are covered?

25 kV AC traction for broad gauge Indian Railways, and 1500 V DC for metro rail systems.

What mast heights are available?

Standard 9 m and 12 m OHE masts, with custom heights fabricated to the approved drawing.

What material and coating specification are railway structures built to?

IS 2062 structural steel and tubular sections per RDSO drawings, hot-dip galvanized to IS 2629 with a minimum coating of 75 microns.

How is dimensional accuracy controlled on repeat railway orders?

Members are CNC plasma cut and robotically welded, and every batch goes through dimensional inspection before galvanizing - railway work demands repeatability across thousands of identical pieces.

Do you supply metro rail projects as well as Indian Railways?

Yes. Precision fabricated traction electrification structures are supplied for metro rail and for industrial sidings, in addition to Indian Railways electrification projects.

Who are the typical buyers?

EPC contractors executing Indian Railways electrification packages, metro rail contractors, and railway divisions procuring OHE structures and channel sleepers directly.
