GRP Transformer Housings
Our GRP transformer housings provide robust protection for electrical equipment. Designed to UK DNO/IDNO standards, they feature Class 2 fire-retardant resin, explosion relief vents, and secure locking systems. The lightweight yet durable construction ensures long-term outdoor performance with minimal maintenance.
Bespoke GRP Enclosures
We create tailored GRP enclosures to meet specific project requirements. Options include security-rated builds, thermal/acoustic insulation, and custom finishes like brick or stone effects. Our CAD-designed solutions accommodate electrical installations, HVAC systems, and elevated structures with integrated cable management.
GRP Roadside Cabinets
These cabinets protect instrumentation and control equipment in utility and rail sectors. Single-moulded GRP construction with fire-retardant resin ensures durability. Available in standard sizes with configurable locks, ventilation, and mounting options to suit diverse operational needs.
Electrical Fit-Out Services
Our NICEIC-accredited team provides complete electrical integration within GRP enclosures. This includes panel fitting, wiring, and compliance with 17th Edition regulations. Factory-installed systems reduce on-site work, ensuring seamless deployment of operational-ready units.
Nationwide Installation
We manage full installation with risk assessments, traffic control, and craneage support. Services include route surveys, hiab offloading, and road closures. Our team ensures safe, compliant setup of enclosures and associated infrastructure across the UK.
