What is FRP grating and when should it be used?
Fiberglass reinforced plastic (FRP) grating is an industrial floor used in a wide range of industries. Usually it appears on sidewalks and elevated platforms.

What is the difference between molded and pultruded fiberglass grating?
Molded fiberglass grating is a grid composed of horizontal and vertical layers of liquid resin and continuous fiberglass rovings. As the name suggests, it is made with large metal molds.

How strong is the fiberglass grille?
FRP gratings can be designed to be strong enough to carry vehicle loads while still weighing less than half the weight of steel gratings. Single composite FRP can withstand significant shock with negligible damage. Unicomposite offers extremely durable gratings to meet the most stringent impact requirements.
Compression molding is the primary choice for most high-volume FRP/composite parts made from BMC, SMC, liquid composites (preforms), GMT or LFTP. The high-pressure forming process produces high-strength, complex parts of various sizes.

Is FRP grating waterproof?
FRP grating is absolutely waterproof. Like other building materials, it does have an absorptive rate, but it’s very low compared to wood or something like that.

Is FRP grating corrosion resistant?
Molded fiberglass reinforced plastic (FRP) grating provides corrosion resistance in the harshest environments. Manufactured by combining a thermoset resin with continuous fiberglass rovings in precision molds, each panel contains approximately 65% ​​resin and 35% fiberglass roving. This combination optimizes corrosion resistance, UV protection and structural integrity.

Where is FRP grating used?
Fiberglass gratings are often used in hazardous or harsh environments that may be exposed to the elements or come into contact with hazardous and corrosive chemicals.
On ships and offshore installations: The robust and durable properties of FRP grating make it ideal for ships and oil rigs or other offshore installations. It can be exposed to wind, rain and extreme temperatures, or submerged in water. It’s also lightweight and relatively easy to transport.
Use flammable materials: FRP grating does not emit any sparks, so it is generally considered a safer alternative to steel or other metals surrounding flammable materials. For example, dropping a metal object on it will not create a spark and may cause the atmospheric gases around it to ignite.
In Electrical Hazardous Locations: Fiberglass grating is often used in electrically hazardous locations because it is non-conductive. Therefore, it reduces the risk of electric shock or other injury in the event of an accident involving electricity.
In chemical plants: FRP grating is non-corrosive. This makes it ideal for walkways, platforms and other surfaces in chemical plants where there is a risk of leaks or spills of corrosive materials.
On complex construction sites: The ease of transporting, storing and cutting FRP grating makes it a flexible and cost-effective solution for on-site work. Construction companies are able to adapt FRP gratings to complex and fluid site layouts using standard cutting tools.
