Properties of GRP


Glass-reinforced plastic (GRP), also known as fibre-reinforced plastic (FRP) is a lightweight, extremely strong and robust material.


The advantages of using GRP over other materials include:


Versatility and Affordability


The lightweight strength of GRP makes it a popular choice for manufacturing. GRP reduces weight and requires less maintenance making it highly attractive over more traditional materials like timber, metal or brick.


The flexibility of GRP and the cost effectiveness of its composite materials also make it an extremely affordable solution and an economical alternative. By using GRP industry can manufacture virtually any component or finished product in any quantity.


Strength and Durability


GRP has a high strength to weight ratio and high flexural strength making it an attractive lightweight material that builds strength into almost any finished product or component. Pound for pound GRP can be stronger than steel and sheet metals.


GRP also has high resistance to environmental extremes and requires very little maintenance - no rust, no painting, no wood rot, plus GRP is non-corrosive and has a much longer life expectancy when compared to a variety of constriction materials.


In highly corrosive environments GRP is the preferred choice over metal, wood or plastic. GRP provides resistance to ultra violet light, extreme temperatures, salt air, and a variety of chemicals including most acids. As GRP is chemically inert and corrosion-resistant, it offers an economical alternative to stainless steel.




GRP products can be manufactured in numerous finishes, textures and colours.  With sheet metal, you get a plain box. GRP products have sleek contours and a superior moulded appearance.




GRP is non-conductive, and can be optimised for operating frequencies using various core materials, making GRP the obvious choice for Radome construction.
