What is GRP? GRP stands for Glass Reinforced Plastic. It is also called fibreglass, composite plastic or FRP. It is strong, extremely light and highly versatile. GRP behaves differently to the conventional thermoplastics that are used in everyday items.

Glass(fiber) Reinforced Plastic (GRP) is a composite material that consists of a polymer matrix and glass fibers. The polymer matrix is usually an epoxy, vinylester, or polyester thermosetting resin.

It has many desirable properties which include:

  • High strength to weight ratio.
  • Excellent durability.
  • Lightweight.
  • Electrically non-conductive.
  • Radar/radio wave transparent.
  • Non-corroding
