This section provides overview, applications, and principles of fiberglass reinforced plastic (frp) gratings. Also, please take a look at the list of 10 fiberglass reinforced plastic (frp) grating manufacturers and their company rankings.
FRP grating is a type of grating made of fiberglass reinforced plastic, which is what FRP stands for.
FRP is a material that combines plastic resin and glass fiber, and its strength is comparable to that of metal, even though it is plastic.
FRP grating is used in various places as a construction material. In daily life, they can be found in aquarium corridors and drain covers. This is because corrosion by seawater will occur if grating made of metal material is used. In industrial applications, grating is used in flue gas desulfurization plants. It is also sometimes used as flooring material for the second floor of houses, stairwells, etc.
FRP is reinforced by mixing glass fiber with plastic. The strength is increased by mixing glass fiber, which has a high elasticity rate and is strong, with plastic, which has a low elasticity rate and is prone to cracking.
FRP grating is lighter than metal grating. Specifically, its exact gravity is about 25% cast iron and 60% of aluminum, and it has excellent corrosion resistance. Being a mixture of plastic and glass fiber, it is difficult to recycle or dispose of.
FRP grating can be colored either by surface painting or by mixing pigments during the molding process.
FRP grating is a lightweight material with excellent corrosion resistance. Therefore, FRP grating is suitable for flooring in corrosive environments such as chemical plants and ships where load reduction is required. The non-slip shape of FRP grating also contributes to preventing pedestrians from falling.
FRP has high lighting performance and allows daylight to reach the first floor from windows on the second floor of a house. It is also possible to change the impression by changing the color. When used as a flooring material, it may cause pain standing barefoot for long periods of time, to prevent this however, polycarbonate is placed on top of FRP to distribute the weight.
FRP grating is an insulator that allows radio waves to pass through and can be easily colored, so it can be used for bridge floor panels, stairs, etc.
The strength of FRP grating is up to 350 kg per square meter, and the life of FRP grating is estimated to be 20~30 years based on the results of outdoor exposure and accelerated exposure tests. Yellowing of the exterior due to ultraviolet rays will occur after 5~10 years of use.
FRP has grating impact resistance against full surface impact. However, there are limitations on impact resistance due to puncture and falling load, so it is necessary to check the information on the manufacturer.
The heat resistance of general FRP grating is about 65~80℃, which is not as high as that of metal. If FRP grating is to be used under high temperature, FRP grating made of special resin should be used.
FRP has grating high weather resistance, and its strength hardly deteriorates due to temperature changes. Therefore, it can be used outdoors. Examples of outdoor applications include balcony flooring, plant walkways, stair treads, drain covers, and exterior wall partitions.
