Advantages of FRP Grating
High corrosion resistance
FRP grating lasts several times longer than steel or galvanised steel grating. In highly corrosive applications, metal products usually deteriorate within a few years, whereas FRP grating panels have a much longer service life, often in excess of 25 years.
High strength, light weight
FRP grating systems offer the strength of steel and weigh only ¼ of steel.
Easy to install
Due to its light weight and simple construction, FRP grating does not require heavy machinery for installation and can be easily assembled with very few people.
Easy to maintain
The durability and corrosion resistance of FRP grating means that there is virtually no maintenance after installation, saving you money year after year!
Slip and wear resistant
Slips and falls are the second leading cause of industrial accidents. While steel can become slippery when it is oiled or wet, FRP grating remains safe even when wet.
Flame retardants
Because its structural glass fibres are manufactured using flame retardant phenolic resins, FRP grating can withstand prolonged direct exposure to fire without compromising its primary structural integrity.
Versatile
FRP grating systems are used to construct raised green roofs, synthetic turf roof decks, raised stone decks, timber boardwalks and other commercial access points such as jetties and breakwater decks.

Composition of FRP Grating
Resin
The resin used in FRP grating can be either polyester, vinyl ester, or epoxy. Each type of resin offers different properties, such as chemical resistance, UV stability, and thermal performance.
Reinforcing Fibers
Glass fibers are the most common type of reinforcing fiber used in FRP grating. They are lightweight, strong, and have excellent tensile strength. Carbon fibers and aramid fibers are also used in specialized applications where higher strength or specific properties are required.
Manufacturing Process of FRP Grating
Pultrusion
This is the most common method for producing FRP grating. In this process, continuous strands of reinforcing fibers are impregnated with resin and pulled through a heated die. The heat causes the resin to cure, forming a solid, continuous profile. The resulting product is a strong, lightweight, and durable grating.
Molding
For more complex shapes or custom designs, FRP grating can be manufactured using a molding process. In this method, the resin and reinforcing fibers are placed in a mold, which is then subjected to heat and pressure to form the desired shape.
Curing
After the resin and fibers are shaped, the material undergoes a curing process. Curing can be done at room temperature or under controlled heat, depending on the type of resin used. This process ensures that the resin fully hardens, providing the final mechanical and chemical properties.
Load Distribution:
FRP grating is designed to distribute loads evenly across its surface. The reinforcing fibers, embedded in the resin matrix, provide the necessary strength and stiffness to support heavy loads.
Corrosion Resistance:
One of the key advantages of FRP grating is its excellent resistance to corrosion. Unlike metal gratings, which can corrode when exposed to moisture, chemicals, or salt, FRP grating remains unaffected.
Non-Conductive Properties:
FRP grating is non-conductive, making it suitable for use in electrical installations and other applications where electrical conductivity is a concern.
Lightweight and Durable:
FRP grating is significantly lighter than traditional metal gratings, making it easier to handle and install. Despite its lightweight nature, it is highly durable and can withstand heavy loads and harsh environmental conditions.
Slip Resistance:
Many FRP gratings are designed with slip-resistant surfaces, which are essential for safety in wet or oily environments. These surfaces can be achieved through the addition of grit or by using a textured surface during the manufacturing process.
Application of FRP Grating
Ship and Off-Shore Rig Plants
FRPs are tough and durable and can withstand any weather condition. Moreover, they are convenient and easy to transport.
Oil and Gas Industry
FRPs can handle high temperatures and has excellent non-conductive and non-corrosive features.
Chemical Plants
FRPs are safe to use in harsh environments because of their non-corrosive properties.
Electrically Hazardous Environment
FRPs are non-conductive. They reduce the risk of injuries from electric shock or fire hazards in power plants.
Complex Construction Sites
FRPs are easy to transport, flexible and easy to store and install, making them ideal for complex construction sites.
Food Industries
FRPs are durable, corrosion resistant and easy to maintain and hence are safe to use in food and barge industries.
