Adept GRP increase production levels


Adept GRP Ltd have recently taken on additional premises with a view to increasing production levels of our ever popular GRP Electrical Cabinets. The Outdoor Weatherproof Cabinets are part of our Standard GRP Enclosure Range, are in continual high demand.

The VR Roadside Range offer Small, Medium and Large walk in GRP Enclosures, all Adept GRP products come with an expected lifespan in excess of 25 years making our GRP Enclosures a very cost effective option when lifespan is considered against initial outlay.

We also produce tailor made, Bespoke GRP Enclosures for situations where a standard GRP Kiosk doesn’t quite meet requirements. Bespoke Enclosures can be small or large, we are normally provided with a brief on what’s required which we then, given our extensive experience, use to produce an Autocad Drawing which we provide for approval prior to commencing manufacture. Delivery of the smaller GRP Cabinets are normally by National Carrier whilst the Larger GRP Housings are delivered on a dedicated vehicle and offloaded/positioned by Hiab.

In addition to being Audited by an external Consultancy Company on a monthly basis, Adept GRP is also Audited on an Annual basis by SGS with a view to meeting IS0 9001:2008 Standards, a standard we gained and have continually met for a number of years.

If you’re looking for assistance with an upcoming Project which requires an Industrial GRP Product  we are the people to speak to, we offer a very personalised service supported by extensive experience within the GRP Industry. Just visit or call 01269 843355 and we’ll guide you through the entire process.

Rooftop GRP Enclosures


A large number of GRP Plant Rooms etc are required to be positioned on existing rooftops, possibly a number of storeys above ground level. Cranage on to roof level as a Ready Built GRP Enclosure is not always an option due to the Site layout or a number of other reasons. One option to overcome such a problem is to consider the possibility of a Service/Goods lift, assuming availability and providing it is of a reasonable size, we can manufacture GRP Enclosures in narrow, smaller panels which will allow them to be transported to roof level with relative ease. The multiple Panels can then be transported across the roof to where they’re to be sited and erected by one of our experienced Site Crews.

In instances where conditions allow the GRP Enclosure to be craned up as a Ready Built, one piece component we would fit Certified Lifting Plates to the Enclosure prior to dispatch, the Slinger/Banksman can then hook the chains up to the lifting plates and commence the lift to the rooftop.

Adept GRP Enclosures are supplied with Risk Assessments/Method Statements on request, we can also provide you with an estimated weight for the GRP Enclosure so as to avoid any potential delays when executing the lift.

Feel free to Contact Us for more information.

GRP vs Steel in Industry


The great Debate over Steel Electrical Feeder Pillars against GRP Electrical Feeder Pillars continues, similar in style and appearance the option of either has been available to Industry for a number of years.

The benefits of Steel Electrical Enclosures

Steel Electrical Enclosures continue to be very popular, they are available in a number of Standard Sizes and are normally available at short notice, smaller units would have a single door normally secured with Triangular Locks, a Ply Backboard to accept Electrical Equipment and the option of a “Root” which can be set in concrete, ensuring a stable base fixing. Adept Steel Cabinets are manufactured from 2mm Zintec Steel Sheet and finished in Green as Standard. The negatives, when compared with a similar Electrical Enclosure manufactured from GRP is the fact that Steel is a conductor of Electricity and its limited lifespan of 8-10 years prior to it showing signs of corrosion.

The benefits of GRP Electrical Enclosures

GRP Electrical Enclosures appear to have the edge when all things are considered. They are also available in a range of Standard Sizes and again, normally available at short notice. Smaller units would come with a Single Lockable Door whilst the larger units would be fitted with Double Doors, they have no central pillar, so full access is provided when both doors are opened. The fact that GRP is maintenance free and has a life expectancy beyond 30 years sees the Doors being hung on Stainless Steel Hinges, secured by Stainless Steel Fixings. GRP Cabinets are designed to provide many decades of trouble free service, they can be manufactured in any Colour from the BS or RAL Range, they can be closed or open based (allowing cables to be fed into the Cabinet from the underside) and accept a range of optional extras such as Viewing Panes in the Doors, Enhanced Locking Systems, Vents but to name a few. GRP is non-conductive and has a Safety edge over Steel Cabinets in that sense.


To summarise, the general trend sees Industry switching from Steel Cabinets to GRP Cabinets, this primarily based on two factors mentioned above, GRP has a far superior lifespan and is a non-conductive material, two very important factors when looking to house Electrical Equipment safely with longevity in mind.

Outdoor GRP Housings


When GRP is mentioned for outdoor grp housings, the acronym used is in reference to Glass Reinforced Plastic. GRP Products are used as a solution to ensure what is inside is secure and kept out of view. The size and scope of products can vary, from GRP Glass Reinforced Cabinets to Housing. Glass Reinforced Plastic (GRP) is an efficient, cost effective and durable way of protecting equipment such as water, telecommunications and industrial equipment.

The advantage of using GRP Housing is that its size and shape can be tailored to a client’s requirements, while the material used keeps the housing low in cost and can provide an attractive, durable building which looks appropriate to the surrounding environment.

GRP Housings are widespread commercial and industrial used, and can be found in places where a company or person requires an enclosed environment to house devices such as a control panel, gas equipment or security features which should not be accessible to the general public. This means GRP Products should be flexible enough to be used in a variety of landscapes, yet secure and long-wearing enough to protect what is inside from the elements and from any outside interference.

GRP Cabinets range


GRP cabinets are widely used in many of our industries that supply us with water, petrol, electricity, gas and much more. These global industries also have the need to use many other GRP products.

Many years ago these global industries used steel and iron that are subject to corrosion and need a lot of maintenance but now they recognise the qualities in GRP so when the cabinets and housings needed renewing they replaced them with GRP.

Due to the locations of some of these cabinets, and the products and contents they house; the GRP cabinets have to be water tight as well as well as having to be securely locked. The versatility of the GRP material and the cost effectiveness has almost replaced the use of traditional metals across the globe.

There are companies operating today that specialise in the production of GRP cabinets and can supply all the extra options that the cabinets may need. Because of the popularity and heavy demand for GRP cabinets many companies stock a wide range of them so that if a customer orders one and they are in stock delivery can be made the next day. This is a big plus for industries that are operating on a time schedule.

Companies who stock GRP cabinets are aware of the customer’s requirements for cabinets and other products in chosen colours and specific styles so the manufacturers are constantly developing the range of these products to meet the customer’s demand.

GRP AKA Fibreglass


Glass Reinforced Plastic is what some people call fibreglass. It can be moulded into any product you can imagine. It has so many uses around the industry and the home, on the street.

Glass reinforced plastic (GRP) opens so many doors to the industry around us. GRP consists of strands of glass that are in resin so that makes it able to withstand compressive and tensile loads.

GRP is a very modern material that allows itself to be moulded into any shape that it needs to be. It can moulded into any shape, size or colour. That is the great thing about it. The industry that work with this material find it very versatile. It light weight and very low maintenance. Whilst its being produced it can be made into a fire retardant product and also a chemical resistant product too.

GRP has great potential for designers and architects. They can push there design ability’s to the limit. More and more people are choosing GRP as there choice of material to use. Every where you look you will find an examples all over the place.

There are lots of examples of what is made out of Glass Reinforced Plastic.

Roofing, theme park rides, water slides, boat hulls, life raft, play equipment GRP Enclosures and the list goes on and on.

It would take an age to write the list of even half of what GRP is used for. Have a good look around you now and see what you can see is GRP, next time you walk down the road have look around you and see what you can see is GRP. You will be surprised at how much you can point out.

It is quickly overtaking steel and other metals. Metal is no comparison. GRP is a lot lighter, it can be moulded into any shape and it can also be any colour that it is needed. It so much more versatile then metal.
