GRP Cabinets, Enclosures & Boxes

What is a GRP Cabinet?

GRP cabinets (also known as GRP boxes and GRP enclosures) are made from Glass-fibre Reinforced Polyester and are strong, durable and shockproof, compact, low maintenance yet light weight. GRP enclosures are corrosion resistant, watertight and UV resistant.

What are GRP Cabinets used for?

GRP cabinets and boxes have high impact protection, they are well insulated and have a high ingress protection rating, this means they are ideal for being used for outdoor watertight enclosures for applications such as electrical, gas, telecoms or meter boxes.

What is a GRP Electrical Cabinet?

A GRP electrical cabinet is an enclosure that protects items such as electrical appliances, power lines and electrical circuits. The use of the GRP material is ideal because it helps insulate from electric shocks and the boxes are UV resistant and watertight.
