What is FRP (Fiber Reinforced Plastic) ?

FRP is a composite material consisting of polyester or vinyl ester resin, which is reinforced with glass fiber and increased physical and chemical strength values. FRP metal, wood, glass, concrete and so on. It is superior to other production materials with its ability to easily gain different features suitable for the purpose of use.

  • GRP  (Glass Fiber Reinforced Plastic) in America
  • FRP  (Fiber Glass Reinforced Plastic) in the UK
  • PRFV in France   (Plastique Renforce de Fibers de Verre)
  • GFK  (Glasfaser Kunstsoffe) in Germany
  • PRFV  (Plastici Rinforzati di Fibro di Vetro) in Italy

 

What is FRP (Fiber Reinforced Plastic) Cover ?

Composite (FRP) covers is available at many locations, such as factories, industrial plants, petrol stations, houses, apartments, streets. Manhole or drainage is generally known as the place where sewage or water network connects to the main system. Manholes and drainage are an important place in the flow of life, this is the main reason for the use of composite (FRP) covers in many points in our country and in the world.

Firstly, cast-iron or metal covers are at the risk of being stolen every day because of scrap value, but composite (FRP) covers no risk to be stolen because composite (FRP) cannot recycle so that there isn’t any scrap value. Theft of cast-iron or metal covers is also affect people’s life because of falling in an open manhole, people can cause serious injury and even death.

At first, the metal and cast-iron covers, which look cheap, but they have so many disadvantages. Cast-iron and metal covers are very heavy in their structure and difficult to carry, but composite (FRP) covers are about 75% lighter than competitors. This provides labor advantage at the time of transport, assembly and replacement.

In addition, because they are lightweight, the process is accelerated thanks to easy removal. It saves you both time and money. Cast-iron and metal covers transmit electricity and heat if no extra treatment is required due to their structure, but composite (FRP) covers do not conduct electricity also their thermal conductivity is very low, so it can be used easily in all areas where work-safety is important.

Composite (FRP) covers do not interrupt radar radiation, so they are preferred in areas where radar and signaling are important, such as airports and military facilities.
