FRP gratings, also known as fiberglass reinforced plastic (FRP) gratings or fiber-reinforced polymer (FRP) gratings, are a type of structural grating or walkway surface made from a combination of fiberglass reinforcement and a thermoset polymer resin matrix.
FRP gratings are designed to provide a durable, corrosion-resistant, and high-strength walking surface or platform in various industrial and commercial applications. FRP gratings are typically made by molding a thermoset resin, such as polyester, vinyl ester, or phenolic, reinforced with glass fiber reinforcements (rovings, mat, or woven roving) in a specific pattern or grid structure.
Types:
High resin content provides resistance to a wide range of chemicals
The coarse quartz grit finish where applied to the walking surface, provides excellent anti-slip performance
Flame retardants are added to the resins to improve the fire resistance
UV inhibitors are incorporated into the resin to reduce the effects of ultraviolet radiation. However, some loss of colour will occur on long exposure
FRP grating resists the effects of high impact loading which may superficially damage the surface but does not allow penetration.
High strength, with E-glass rovings moulded into a square grid grating pattern, provides a stiff and light flooring panel suitable for foot traffic over a wide range of spans. See span/load/deflection tables for each grating pattern.
Due to the box pattern arrangement, FRP grating has load bar strength in both directions.
The lightweight nature of FRP grating allows for ease of
handling compared with other materials.
The non-metallic properties of FRP grating makes it ideal for electrically hazardous locations.
FRP grating does not cause any interference and is transparent to radio frequency transmissions.
FRP grating with plain and concave upper surfaces will not cause sparking when impacted by metallic objects.
Compared to other materials, the use of FRP grating results in a long life product with low installation costs.
