01 — Girder types

Plate. Box.
Crane. Gantry.
Bridge.

Every girder type detailed and built under one contract. Camber set at detailing stage, match-marked in erection sequence, NDT records travel with the steel.

G/01

Plate girders

Built-up welded plate girders for spans where standard rolled sections are insufficient. Flange and web plates profiled, welded and stiffened to design.

G/02

Box girders

Closed-section box girders for torsional stiffness on bridges, conveyor galleries and heavy process structures.

G/03

Crane girders

Runway girders for overhead travelling cranes, designed for fatigue loading with rail alignment checked before dispatch.

G/04

Gantry girders

Portal and gantry girders for heavy-lift applications, including surge and lateral bracing connections.

G/05

Bridge girders

Road and foot over-bridge girders, detailed for site splicing and cambered to specification.

G/06

Conveyor galleries

Gallery structures for mining and process plants, supplied as match-marked assemblies for bolt-up erection on site.

02 — Capability

Detailing to
dispatch.

Every stage from analysis to match-marking is controlled under one contract, whether the work is done on our own floor or placed with a qualified shop.

C/01

Detailing & analysis

Detailed to IS 800 or AISC 360. Camber, stiffener spacing and splice locations set at drawing stage so site fit-up is predictable.

C/02

SAW, FCAW & MMAW welding

Submerged arc for long web-to-flange seams, flux-cored and manual metal arc for stiffeners, splices and attachments.

C/03

Web profiling to 40 mm

Full-length plate in one setup up to 3 m × 14 m, eliminating unnecessary splices and reducing site work.

C/04

NDT & inspection

Ultrasonic, magnetic particle or radiographic testing to your specification. Reports and records travel with the steel.

C/05

Match-marking

Every piece marked in erection sequence so your site crew can bolt up without re-measuring.

C/06

Surface treatment

Blast cleaning and primer applied before dispatch where required, with DFT records included.

05 — Straight answers

What clients
ask us.

Can you supply girders?

Yes — plate, box, crane and gantry girders, and bridge girders. Detailed by us, camber and stiffeners set at drawing stage, webs profiled to 40 mm and 14 m so there are no unnecessary splices. Match-marked, NDT to spec, records travel with the steel.

Do you own the fabrication facility?

Our own works at Liluah cover stocking, bandsaw cutting, welding, handling, cranage and dispatch. Profile cutting, girder build-up and erection are placed with shops we qualify and supervise under the same quality procedures.

What welding processes do you use?

SAW (submerged arc) for long web-to-flange seams, FCAW (flux-cored arc) and MMAW (manual metal arc) for stiffeners, splices and attachments.

What NDT is available?

Ultrasonic, magnetic particle and radiographic testing to your specification. NDT reports and records travel with the steel.

Do you deliver outside West Bengal?

Yes. Pan-India dispatch, including part loads and scheduled consignments. Freight is quoted separately so you can compare it.
