Built for the long term

Infrastructure is built for decades and used by millions. Its steel has to span far, carry heavy and dynamic loads, resist weather and corrosion, and go up with as little disruption to traffic and operations as possible – often in night shifts and possession windows.

Below are the infrastructure sub-sectors we serve and the structures in each.

Ứng dụng

Why infrastructure owners choose steel

Long spans

Terminals, canopies and bridges with few supports.

Minimal disruption

Modules lifted in during short closures and night possessions.

Designed to the owner’s specification

Bridge, transport and utility codes and design lives.

Corrosion protection for decades

Paint and galvanising systems to ISO 12944 up to C5 and CX.

Precise interfaces

Trial assembly and survey-based detailing for connections to existing structures.

Full documentation

ITP, traceability and quality dossier for the asset owner.

Pedestrian bridges

Spans lifted in overnight

Our steel pedestrian bridges are fabricated and trial-assembled as complete spans, protected to the environment and lifted into place in short road or rail closures – with dynamic analysis for walking comfort.

Design workflow

From proposal drawings to as-built – in every sector

Infrastructure projects follow the same six-step design workflow, with the quality control and MDR the asset owner needs at handover.

Reference

Design drivers by infrastructure type

Indicative design drivers for early planning – confirmed for each project.

Infrastructure structure types
Structure type	Main design drivers	Typical features
Pedestrian bridge	Span, walking comfort, lifting	Truss or box girders, C4–C5 coatings
Airport terminal	Very long spans, architecture	Curved trusses, glazed façades
Station canopy	Train clearances, possessions	Repetitive canopy frames
Toll canopy	Wind uplift, branding	Long cantilevers
Port structure	Corrosion, heavy loads	Duplex coatings, heavy frames
Utility building	Equipment loads, cranes	Crane runways, platforms
