Discover our range of enclosures

We supply a great range of enclosures in a range of materials including PVC, GRP, metal sheet steel and stainless steel and moutning plates to suit.


If you feel your electrical systems are exposed or vulnerable to damage, GRP cabinets are the best way to preserve them. They are the perfect solution to your electrical packaging needs.

GRP enclosures are electrical cabinets designed to protect your wiring from environmental damage. They are strong, durable, waterproof and highly resistant to corrosion and UV damage, making them the ultimate defence against the elements.

GRP stands for glass fibre reinforced plastics in the UK and is referred to as FRP in the US and Canada. By reinforcing the plastic with fibreglass, it helps give the material the robustness of a metal enclosure, all the while remaining lightweight and low-maintenance. This is what makes it such a popular choice of material for electrical cabinets.

GRP, short for Glass Reinforced Plastic, is a super-strong, lightweight plastic that is extremely versatile. GRP is also known as, composite plastics, fibreglass or FRP (Fibre-Reinforced Plastic).

The main benefit of an enclosure made of GRP (Glass Reinforced Plastic) is its extremely effective ability to protect your wiring from environmental damage. They are waterproof, highly resistant to corrosion and UV damage but most of all immune to electrical conduction.

If manufactured correctly and to a high standard, pound for pound GRP can be stronger than steel. GRP also boasts its ability to be maintenance-free and has a safety edge over steel cabinets due to its not conductive properties.
