Fiberglass Reinforced Polymer (FRP) grating—also referred to as composite grating—is a resin-fiberglass composite material used for the surfaces of walkways, stairs, platforms and other load-bearing structures. It is available in pultruded and molded forms, both of which can be customized to meet specific performance and safety requirements.
Pultruded fiberglass gratings are fabricated from corrosion-resistant I- or T- bars that are connected and secured through a unique notch and groove bar system. They are suitable for applications that require high strength and stiffness. Molded fiberglass gratings are molded and cured into the desired shape. They are ideal for structures that need extensive fabrication and cutting as well as applications that involve corrosive compounds or require a large open area.
The fiberglass pultrusion process utilizes a caterpillar-like machine to pull the fiberglass material through the various steps. First, fiberglass strands are guided into parallel bundles that run across the length of the component. Then, fiberglass mat is added to provide multidirectional reinforcement. Next, resin is applied to the fiberglass materials, and a surface veil is wrapped around the entire assembly. Afterward, the composite is pulled through a heated die, which cures it. Finally, the cured material is cut to the desired lengths with a cut-off saw, and the individual bars are assembled to form grating panels.
FRP gratings are well-suited for highly corrosive environments or applications involving commercial and architectural applications. Typical uses include:
