GRP Material

GRP Material, known as Glass Reinforced Plastic is an extremely common material which is suitable for the manufacturing of many products. GRP normally consists of a Polyester Resin and Glass Reinforcement such as a Chopped Strand Mat.

Brief History of GRP Material

GRP laminates have been produced since the 1940’s with its origins stemming from the boat building industry. In World War II, GRP was also used to protect radar equipment and ducting for aeroplane engine nacelles. Shortages of metal during the war drove manufacturers to source alternative materials, GRP was one of the materials which could be used.

  • Low technology requirements
  • Durability

GRP Industries

Boating and Marine

GRP Boat Building and Restoration has come a long way since its inception in the 1940’s. GRP is now a convenient and often more affordable way to create a boat using the hand lay-up method or from a mould for smaller boats. Epoxy ResinLloyd’s Approved Resin & Vinylester Resin are all popular resins used in this industry.

Wind Energy

The demand for renewable energy is increasing as countries across the globe look to reduce the consumption of fossil fuels and comply with global regulations. GRP is a rising star for this industry. As a lightweight, composite material that is extremely strong and resistant to corrosion it is perfect for the elongated blades which form part of the wind turbines.


Campervans, custom car kits, bumpers and replacement car body parts can all be manufactured from and repaired with GRP. Read more on repairing a camper van with GRP to find out how easy it is to work with GRP in the automotive industry.

Home Improvements

GRP at home is not something that automatically comes to mind but its popularity is certainly on the rise in the flat roofing industry. Felt and Rubber have traditionally been the materials of choice for flat roofing. This is changing as requirements for a cold pour system to aid safety on site, as well as a material which will not corrode under harsh weather conditions. GRP Roofs are also very easy to clean and maintain. All in one GRP Roofing Kits and GRP Roof Trims are the most popular materials for this type of project.

Leisure Industry

GRP is used across the Leisure industry from water slides to rides, towers and castles. It can also be used in the manufacture of Health and Leisure facilities for Jacuzzis and Spa Tubs.
