We recently designed, manufactured, and delivered a bespoke GRP substation with a C5 Corrosion Resistant painted steel base.


Engineered for durability, safety, and operational efficiency, this unit demonstrates our capability to combine GRP technology with structural steel elements to meet complex site requirements.


Key Features:


  • Weatherproof GRP Construction – protects critical electrical equipment from the elements.

  • C5 Corrosion Resistant painted steel base - Ensures maximum durability and long-term protection in the harshest coastal, industrial, and high-humidity environments.

  • Customised Layout – designed specifically for the client’s operational and site requirements.

  • Low-Maintenance & Long-Lasting – corrosion-resistant materials ensure longevity and minimal upkeep.


This substation highlights our expertise in delivering engineered solutions that seamlessly blend function, safety, and resilience.
