Hill Grwp has successfully designed, manufactured, and delivered another bespoke GRP substation enclosure, fully pre-fabricated in-house to meet our client’s precise specifications. This solution demonstrates our commitment to delivering safe, reliable, and high-quality enclosure solutions for industrial and infrastructure projects:

In modern industrial and commercial construction, roof entry enclosures are a critical but often underestimated requirement. Whether it is for ductwork, pipework, or cable entry systems, the way services are routed through a building envelope has a direct impact on safety, compliance, and long-term operational performance. 

This latest build was designed, manufactured, and fully fitted out in-house to meet our client’s exact requirements. Constructed from GRP (Glass Reinforced Plastic) for maximum durability, weather resistance, and low maintenance. Fully equipped with internal electrics, lighting, and access points for easy installation and long-term reliability.

GRP (Glass Reinforced Plastic) enclosures are commonly used across utilities, energy, and industrial infrastructure projects. At Hill Grwp, we’ve delivered countless GRP housing solutions for applications like pump stations, electrical equipment, and metering.  Here are some insights we’ve gathered from working with GRP housings on a day-to-day basis

Behind every ⚡ “Danger of Death – Keep Out” sign is a responsibility:  - To protect the public  - To secure critical assets  - To support the industries that power our everyday lives. At Hill Grwp Ltd, safety isn’t just a feature of our GRP buildings—it's our promise.  

At Hill Grwp, we design and manufacture robust GRP switchgear substations and oil & gas metering housings built to meet the most demanding industry standards.

Our team is currently hard at work delivering multiple switchgear substations for valued clients. Each project is at a different stage of the build, and it’s great to see the progress taking shape day by day.

Our custom galvanised steel staircases provide a reliable, long-lasting access solution for a wide range of industrial and commercial environments — from utility facilities to power and energy infrastructure.  Each staircase is built to integrate seamlessly with GRP enclosures, prefabricated pump rooms, switchgear housings, and other modular building systems supplied by Hill Grwp. 

This particular unit was built for a client with year-round exposure to harsh conditions — and with a GRP outer shell and a galvanised steel base, it’s engineered for reliable, low-maintenance protection. 

Here’s a look behind the scenes at Hill Grwp Ltd — this steel base frame is now on its way to the galvanising plant, a key step in the fabrication of our pre-packaged GRP enclosures and sprinkler pump houses.
