Benefits of GRP

Categories: Tags:

GRP (Glass Reinforced Plastic) has numerous benefits that are hugely beneficial in the manufacture of GRP Enclosures.

The primary benefits would be its Lifespan, GRP Enclosures remain operational for well over 25 years, they don’t need any painting or staining, a little light lubricating Oil on the hinges and lock will ensure trouble free service for years to come.


Another such advantage would be the flexibility in Design

GRP Panels can be produced in specified sizes. We often encounter instances whereas a GRP Enclosure is required at roof top level, the Service Lift is very often too small so we resolve the issue by Manufacturing the Wall/Roof Panels to suit the service lift. We then offer a Service whereas an Adept GRP Site Crew will attend Site and erect the Enclosure in the requested location.


Adept GRP Enclosures (also referred to as GRP Kiosks) are Non Conductive and are finished internally with a Fire Retardant Resin.

They are manufactured with the end use in mind, the position of the Doors and any other features dictated by the Customer prior to the commencement of manufacture. Further details are available at



We also produce a range of GRP Electrical Enclosures, these come in set sizes but with 16 options on size you’re almost sure to find something close to what you want. If you’d like to browse our Standard Range of GRP Cabinets you can find Drawings and prices at

GRP tanks


Glass Reinforced Plastic, is a material where a plastic resin has tiny fibres of glass inside. This is where the strength comes from. GRP can and is used for so many things in the industry and the home. Its strength and durability will take on almost anything.

It was developed during the second world war to build part of the planes, so you can imagine how strong it is and it goes from strength to strength all the time. Being used for a lot more things then you realise.

When an industrial engineer has a steel tank that needs replacing, they will replace it with a Glass Reinforced Plastic tank. GRP tanks are replacing steel ones all the time. Steel tanks need repairing all and attention all the time, you won’t get that with a Glass Reinforced Tank. These will not need any maintenance.

Glass Reinforced Plastic can be used for industrial tanks that can hold up to 300 tonnes. If the tank is smaller it can be made out of chopped strand mat cast over a thermo inner tank which acts as a preform during construction. More and more tanks these days are being made using woven mat with fibres. They use Glass Reinforced Plastic for chemical storage because of the strength of it. It can take that kind of punishment.

Glass Reinforced Plastic can be used for so many things. Storage tanks are only one of the things it can be used for. It is a very versatile material.

Piping is a popular one too along with windows, doors and all other household and industrial things.
