By manufacturing key components in a controlled environment, we reduce installation time on site, improve quality control and accelerate project delivery for our clients.
Our facilities in Amsterdam and Frankfurt produce electrical containment systems, modular assemblies and infrastructure components, ready for deployment to projects across Europe, including the UK, Ireland, Frankfurt, Amsterdam and Paris.
What We Prefabricate
Our prefabrication teams produce electrical containment systems, modular assemblies and infrastructure components offsite, so they arrive on site ready to install.

Working in a controlled workshop environment means every assembly is built, checked and labelled before it leaves the facility, reducing complexity and rework on site.
Offsite capabilities
- Modular electrical containment manufacturing
- Cable tray and cable ladder assemblies
- Modular electrical assemblies
- Infrastructure components built to project specification
- Pre-checked and labelled before delivery
- Coordinated storage and just-in-time delivery
