GRP is a strong, durable and lightweight construction material that can be a substitute for steel, wood or plastic. To find out more about GRP, visit our What Is GRP page.
GRP stands for Glass Reinforced Plastic (GRP). It is a composite material, or fibre-reinforce polymer, created using a plastic reinforced by fine fibres made of glass. The composite material is commonly referred to as Fibreglass.
GRP has many desirable properties, including a high strength-to-weight ratio, strong durability, flexibility in shape/colour/texture, easy maintenance, long-life expectancy and total resistance to corrosion. As a result of these qualities, it is an extremely useful material for a wide range of applications in a number of different industries. Applications for composites are rapidly evolving. Reduced mass, corrosion resistance and superior weight-strength ratios offer significant benefits in the built environment. From an initial range of niche uses to industry-wide delivery, the potential for implementation is limited only by creative design and imagination.
GRP is an economical material. Compared to stainless steel, GRP is more affordable and, as a result of its long-life expectancy, it is a worthwhile investment for businesses.
The use of GRP is growing. As more and more industries discover the desirable properties of this material, its use is expanding. GRP is beginning to replace materials including steel and wood. It is a safe material to use where electricity, chemicals, corrosive substances or heavy loads are regularly in the vicinity. These composites have generated exciting results in bridges, buildings, structures and retro fitting protective profiles because they are are lighter, stronger and quicker to build.
Is GRP waterproof?
GRP is waterproof, making it ideal for use on roofs, boats and other outdoor applications.
Is GRP UV resistant?
GRP has a high resistance to ultraviolet light.
Is GRP a thermoplastic?
GRP is made using a thermosetting resin. This means that it can only be heated up and shaped once. This is different to a thermoplastic, which can be heated and shaped repeatedly. By using a thermosetting resin, this prevents any melting/dripping should the product be exposed to high heats.
Is GRP a thermal insulator?
GRP can be made as a thermal insulator. This is achieved by using a special type of glass fibre together with the plastic.
Is GRP flammable/combustible?
Many of the chemicals used in GRP production are harmful and hazardous, and this includes flammable substances. However, GRP can be custom-made to be fire resistant by using different resins which are not flammable. GRP includes non-sparking qualities which means it can be used on sites where combustible gases may be used. View our fire resistance data here.
Is GRP acid resistant?
GRP can be made resistant to different types of acid. It depends on the acid type and the concentration used as to the effect it may have on the product. View our chemical resistance data here.
GRP is an extremely durable material. It is used in a variety of different applications precisely because of this quality, including construction yards, railways and engineering. It can withstand poor weather conditions with minimal suffering and has a long-life expectancy, regardless of wear and tear.
The process of pultrusion creates continuous lengths of GRP. The process is efficient, eco-friendly and low in cost. Pultruded GRP has a high durability and is light and quick to build. Our pultruded profiles are manufactured using the pultrusion process, or the &#;pulled&#; process. The raw material is pulled through a step by step process.
Stage 1: This starts by pulling in two forms of fibreglass reinforcement. Creels of fibreglass roving provide uni-directional strength along the length of the profile, and rolls of woven fibreglass mat provide multi-directional reinforcement.
Stage 2: The fibreglass reinforcements are then pulled through a bath of thermoset resin, typically polyester or vinyl ester.
Stage 3: A surface veil is added to enhance the surface appearance of the final product just before it is pulled into the heated dye.
Stage 4: Wet-Out reinforcements are pulled through the heated dye, which allows the resin to cure and harden. Once it comes away from the dye, a solid, rigid profile is produced in the exact shape of the dye cavity, which has been formed with all the reinforcements laminated inside. It can then be cut to specification.

GRP is a composite material. Sometimes called a fibre-reinforced polymer (FRP), it is made from glass fibres that reinforce the plastic used.
No. GRP stands for Glass Reinforced Plastic, and it is a type of FRP (Fibre-Reinforced Plastic). However, the two terms are often used interchangeably.
GRP stands for Glass Reinforced Plastic, and FRP stands for Fibre Reinforced Polymer. In essence, the key difference is that GRP specifically uses glass fibres combined with plastic and a resin. It is just one type of FRP.
FRP stands for Fibreglass Reinforced Polymer, also known as composites. These are a combination of resin (such as polyester and vinyl ester), reinforcements (such as fibreglass roving and mat) and additives (such as pigments, UV inhibitors, fire retardants and surface veils). Fibreglass has the strength of steel at a fraction of the weight. It will not corrode, rot, warp, attract insect damage or conduct electricity. It can be formed into countless FRP Profiles to fit your specification. The dense fibre core makes the structural shapes hard and strong, and their absolute values of vertical flexible strength and impact strength are higher than those of common steels.
The installation process for GRP saves a considerable amount of time. GRP is easily fitted into a vast range of different environments and is long-lasting, meaning that it doesn&#;t requiring replacing soon after its installation. GRP products save time and money without the need for any heavy lifting gear/cranes or hot works /welding. GRP grating, sheets, stair nosings, tactile pavers and pultruded profiles are not labour-intensive. They can be simply bolted, glued and screwed in place and this drastically saves on the overall time it takes to install GRP.

The life-expectancy of GRP products can vary from 25 years to 100 years and over. GRP is extremely long-lasting and survives well, even in environments which suffer from constant wear and tear.
You can paint GRP using fibre paint, but first you need to know if you are painting directly onto the gelcoat or onto a previously painted surface. If you are painting onto a gelcoat, then make sure the surface is clean. You can use a brush, roller or spray, depending on the area you need to paint. If you are painting onto a previously painted surface, ensure you have removed the previous paint by sanding the surface carefully. Depending on what you are painting, this will influence the qualities of the paint (such as whether it needs to be waterproof). Make sure you research this carefully before purchasing your paint.
GRP Anti-slip panels are large sheets of flat GRP. They can come in a variety of different colours and finishes, including textured, and can be made to suit specific requirements. Textured panels are often required in areas of high footfall, or in environments in which surfaces have the potential to become wet and slippery. Textured panels offer a safe surface to walk on due to their superior slip-resistance quality. For more information, visit our GRP Sheets and Panels page and discover more about this product.
GRP grating has a number of benefits when compared to other materials, such as steel for example. These include:
When deciding what GRP grating to choose, make sure you fully understand its application. Make a note of the environment it would be fitted into (e.g. wet conditions, slippery, low-lighting) and the size of the area you require the grating for. Also, consider the load the grating would need to bear (e.g. people, heavy trucks or cranes).
Moulded grating is often referred to as GRP or FRP grating.
Moulded grating offers different grating designs but the general structure is the same.
The mould includes a mould cavity, ejector pin de-moulding system, heating system and the base. To produce a GRP grating panel, there is a three-stage process:
Stage 1: The mould cavity is the core part of the whole mould. It is composed of a face-plate, mould block and side close.
Stage 2: The ejector pin de-moulding system is composed of the ejector pin cover and support frame.
Stage 3: The heating system is the essential system of moulded grating. The polyester resin is cured hard after heating. This heating system is composed of electric heating tubes and the connecting system, which connects the inner heating system with the exterior heating system.
GRP handrails have a number of benefits. These include being easy to assemble in a number of environments including stairwells, walkways and ramps. They are very strong, lightweight and easy to maintain. They are safe to use in areas which handle chemicals and corrosive substances. They also do not require painting and, therefore, save on maintenance costs. For further information on our GRP Handrails, visit our page and discover more about the benefits of this product.
GRP is a plastic, and plastics are generally assumed to be unsustainable for the environment. This is true for plastics including PVA and PVC, which are considered to be the worst in terms of sustainability. This is because they break down fast in outdoor environments. Although this sounds beneficial, it means that the product is absorbed into the earth quicker and pollutes the ground faster. However, the resins used in GRP are far stronger than other plastics. This means that they do not break down in the same way as other, more common, types of plastic. Most GRP products have a lifespan of over 50 years, with some over 100 years, which results in the product being better for the environment and better for businesses budgets too.
GRP can be recycled. However, the facilities able to recycle it are not common. There has been a surge in research and the development of technology in order to re-use and recycle GRP, and this is seeing some excellent progress.

Slips, trips and falls are a leading cause of workplace accidents and cost employers billions of dollars each year in lost productivity and business. In fact, the second leading cause of unintentional injury-related death, is falls.
According to the Bureau of Labor Statistics, over 1,000 workers die each year as a result of a slip, trip or fall and countless other mild or serious injuries resulting in days away from work. It is therefore of utmost importance for companies, organisations and institutions to understand the hazards.
If accidents happen due to a lack of safety measures on a walkway or areas in which people walk or work on, a company may be held liable for the injuries and damages suffered by the injured party. This can result in significant legal and financial consequences for the company, organisation or institutions, including:
Slips, Trips & Falls &#; Occupational Health & Safety (ohsonline.com)
Please view our installation and cutting guide for Grating here.
Installing non slip grating is easy. It might also require that the product is cut to size on size. That is easily done by following our installation guide.
Cutting grating is similar to working with wood, with some slight differences. To obtain clean, precise and good quality cuts, it is recommended to use diamond tipped circular blades of the type that is used for bricks.
Non slip gratings are generally considered to be sustainable due to their durability, low maintenance requirements, and resistance to corrosion and degradation. In terms of reuse, these safety gratings can often be removed and reused if they are in good condition. They can also be cut and reshaped to fit different applications.
For recycling, the process for GRP is not yet widely established and the technology for recycling is still developing.
Several factors must be taken into consideration when choosing the right gratings to ensure safety, compliance, durability and cost-effectiveness of the product &#; including:
Fiberglass non slip grating is available with an efficient non-slip surface. That makes them an ideal, value for money alternative to normal steel grates &#; and a perfect walkway grating option.
