Product Description
FRP grating refers to Fiberglass Reinforced Plastic grating, it is a type of firm structure made from fiberglass, cast resin and then molded or pultruded into grating plate. This type of grating has outstanding bi-directional mechanical properties, which is stronger than the other types of gratings.
The hole type of FRP grating can be square or rectangular. FRP grating has various specs with different thickness, opening size and overall sizes. The different specs can be used in different applications.
FRP grating has a wide range of applications, such as stair treads, walkways, drainage cover and other applications. Here are all types of FRP gratings for choice. Just choose them according to your requirements. If you have other requirements, just tell us and we will customize them for you.
