GRP ENCLOSURES
GRP (Glass Reinforced Plastic) enclosures, often referred to as fiberglass housings, are specialized, non-corrosive cabinets used to protect sensitive industrial, electrical, and mechanical equipment in harsh outdoor or indoor environments. They are favoured for their extreme durability, with a typical lifespan exceeding 20–30 years.
Use of GRP Enclosures
Utilities & Energy: Housing electrical switchgear, transformers, and distribution boards.
Gas & Water: Protecting gas governors, water meters, and pump control panels.
Telecoms & Data: Sheltering communication equipment, fibre optic connections, and broadband cabinets.
Transport & Infrastructure: Used for roadside monitoring, railway signalling equipment, and EV charging stations.
Industrial & Chemical: Providing explosion-proof or chemically resistant storage for machinery controls in, for example, wastewater treatment plants.
Public Sector: Housing CCTV, security systems, and street lighting controls.
Welfare Units: Used for security cabins, gatehouses and, in some cases, small walk-in enclosures for site work.
Makeup and Composition
GRP enclosures are manufactured from a composite material combining polymer resin and glass fibre via hand lay-up production within moulds and also covering a wooden or steel framing.
Material Components:
Glass Fibres: Provide high tensile strength and stiffness.
Polyester Resin: Acts as the matrix, holding the fibres together and providing environmental resistance.
Gel Coat: A durable exterior coating that provides UV protection and a smooth finish. Most common colours are Green, Grey or Black although a large variety of colours are available on request.
Construction Details
Reinforcement: Usually fire-retardant (BS476 Part 7, Class 2) to prevent the spread of flame.
Core: Often feature a 12mm or 18mm treated plywood core for added strength.
IP Rating: Generally, these cabinets provide high ingress protection, typically ranging from IP55 (dust/weatherproof) to IP65 or IP66 (dust-tight and water-resistant).
Standard Fittings: High grade 304 grade Stainless steel hinges, locking systems, lock covers & door retainers, fibreglass encapsulated steel bolt-down flanges for securing to the ground.
Key Benefits
Corrosion Resistance: Unlike metal, GRP does not rust, making it ideal for coastal or harsh, corrosive environments.
Non-Conductive: Superior electrical insulation properties make them safer for high-voltage applications.
Lightweight & Strong: High strength-to-weight ratio makes them easier to transport and install than steel.
Low Maintenance: Requires no painting, and resists UV, chemicals, and temperature fluctuations.
