Structural steelworks for EV charging infrastructure
Bespoke overhead steel gantries and structural installations for high-throughput EV charging depots. Design, fabrication, and installation delivered as one integrated scope
Steel structures for high-throughput EV charging sites
As EV charging infrastructure evolves, many sites require more than ground-mounted chargers. ADDCharge specialises in the design and installation of bespoke structural steel works for complex EV charging environments, including large overhead steel gantries for cable reel and suspended charging systems. These solutions are critical for high-throughput fleet depots, bus facilities, and HGV charging sites where space, vehicle movement, and operational efficiency are key considerations.
Our structural steel capability is fully integrated with our civil and electrical engineering services, allowing us to deliver overhead charging systems from concept through to installation and energisation.

Bespoke overhead steel gantries for cable reel chargers
ADDCharge has extensive experience delivering large, custom-engineered overhead steel gantries designed to support cable reel EV chargers and suspended charging equipment. These structures allow power cables to be positioned safely above vehicle movement areas, reducing ground clutter, improving safety, and increasing depot efficiency.
Each gantry is engineered specifically for the site, taking into account:
- Span lengths and clearances for HGVs, buses, or fleets
- Loadings from cable reels, containment, and electrical equipment
- Wind, impact, and operational loading requirements
- Future expansion and additional charger capacity
These are not off-the-shelf solutions. Every structure is bespoke, ensuring performance, durability, and compliance for demanding EV environments.
Structural design, calculations and compliance
ADDCharge provides a full design-to-installation structural steel service. This includes detailed structural design, engineering calculations, and fabrication drawings produced to relevant UK standards.
Our service covers:
- Structural steel design and calculation packages
- Coordination with electrical layouts and charger locations
- Compliance with planning, building control, and client standards
- Fabrication detailing for efficient and accurate installation
By managing the structural design in-house and in coordination with the wider project, we eliminate design disconnects and ensure steelwork integrates seamlessly with both civil bases and electrical systems.
Civil bases and concrete foundations
Structural steel installations are only as strong as the ground they are built on. ADDCharge delivers large reinforced concrete foundation bases designed to support heavy steel gantries and ongoing operational loads.
Our civil works include:
- Excavation and ground preparation
- Reinforced concrete foundations and pile caps where required
- Holding-down bolt systems and base plates
- Integration with drainage and hardstanding
These foundation works are engineered specifically for overhead charger systems, ensuring long-term stability even under dynamic loading from suspended cables and repeated vehicle movements.
Installation in live and operational environments
Many overhead gantry installations are delivered on live operational sites, such as fleet depots or logistics hubs. ADDCharge’s teams are experienced in managing tight access, restricted working hours, and phased installation to minimise disruption.
Because we self-deliver civil, steel, and electrical works, we can sequence installation efficiently, installing bases, erecting steelwork, and integrating electrical containment without delay or misalignment between contractors.
Standards and credentials
ADDCharge’s structural steel works enable EV charging sites to operate safely, efficiently, and at scale. Whether supporting cable reel chargers, suspended systems, or future high-power charging technologies, our bespoke steel solutions are engineered for today’s demands and tomorrow’s growth.
