GRP enclosures are weatherproof housings made from glass reinforced plastic, also called fibreglass, used to protect electrical, control and metering equipment in outdoor and exposed locations. Because GRP does not rust, is electrically non-conductive and is far lighter than steel, it has become the standard choice across the electrical, utilities and construction sectors.
Adept GRP manufactures both a stocked standard range and fully bespoke enclosures from our facility in Burry Port, South Wales, supplying DNOs, utilities contractors, electrical wholesalers and end users throughout the UK.

GRP enclosures are weatherproof housings made from glass reinforced plastic, built to protect electrical equipment, metering and control gear in exposed and outdoor environments. Often called fibreglass enclosures, they are the natural choice wherever a steel housing would corrode, and wherever a lightweight, non-conductive enclosure is needed.
Adept GRP designs and manufactures GRP enclosures from our facility in South Wales, supplying electrical wholesalers, distribution network operators, utilities contractors and the construction sector throughout the UK. From stock sizes ready to dispatch to housings built to an exact specification, every enclosure is engineered for years of reliable outdoor service with very little maintenance.
