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.
Sub-sectors & building types
Infrastructure sub-sectors and structures
From footbridges to airport terminals, ports and power.
01
02Aviation
Long-span terminals and hangars with large openings.
- Passenger terminals
- Aircraft hangars
- Air cargo terminals
- Fire stations and support buildings
- Airside canopies and walkways
03Rail & metro
Canopies, depots and footbridges built around live railways.
- Station platform canopies
- Station buildings and concourses
- Rolling-stock depots and workshops
- Track-crossing footbridges
- Maintenance sheds
04Roads & bus
Canopies and buildings for traffic that never stops.
- Toll plaza canopies

- Highway service areas
- Maintenance depots
05Ports & marine
Warehouses, terminals and marine steel for salt-air exposure.
- Port warehouses and sheds
- Ferry and passenger terminals
- Jetties, walkways and platforms
- Conveyor galleries and transfer towers
- Ship repair workshops
06Energy & utilities
Plant buildings and support steel for power, water and telecom.

用途
Why infrastructure owners choose steel
01
Long spans
Terminals, canopies and bridges with few supports.
02
Minimal disruption
Modules lifted in during short closures and night possessions.
03
Designed to the owner’s specification
Bridge, transport and utility codes and design lives.
04
Corrosion protection for decades
Paint and galvanising systems to ISO 12944 up to C5 and CX.
05
Precise interfaces
Trial assembly and survey-based detailing for connections to existing structures.
06
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.
| 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 |

IAS AC472FAQ
よくある質問
Do you fabricate steel bridges?
Yes – pedestrian and cycle bridges, skywalks and link bridges, plus conveyor and pipe bridges. Vehicular bridge girders are considered per project.
Can you work to the owner’s specification?
Yes – we review the specification and its referenced standards and agree deviations before fabrication.
How do you minimise disruption?
Spans and modules are trial-assembled in the factory and lifted in during short closures or possessions.
What corrosion protection do you offer?
Paint and galvanising systems to ISO 12944 up to C5 and CX, with full inspection records.
