Fiberglass Hollow Core Panel
Fiberglass hollow core panel is a lightweight composite panel made from fiberglass reinforced plastic (FRP/GRP) with an internal hollow core cross-section. It is used in industrial, marine, and construction applications where weight reduction and corrosion resistance are required. Performance depends on panel dimensions, core configuration, resin system, and support conditions.
Fiberglass hollow core panel is a composite panel produced from fiberglass reinforced plastic (FRP/GRP) and formed with an internal hollow core cross-section. The hollow core reduces overall panel weight while maintaining a rigid, flat surface for structural and non-structural applications. The panel is supplied in standard and custom dimensions for use in flooring, cladding, platforms, and modular systems.
The panel is made from fiberglass reinforced plastic, combining glass fiber reinforcement with a thermosetting resin matrix. The hollow core cross-section is integrated into the panel design to reduce weight while contributing to stiffness. Panel dimensions and wall thickness are determined by expected loads and support conditions.
Resin system selection depends on chemical exposure, service temperature, and UV conditions. Standard resin options may include isophthalic polyester and vinyl ester, depending on project requirements. Flame-retardant resin formulations may be supplied for applications requiring specific fire performance.
The panel surface can be supplied with a smooth or textured finish, depending on application requirements. Custom dimensions and cross-sections are available subject to manufacturing capabilities.
FRP hollow core panels are commonly used in environments where lightweight construction and corrosion resistance are priorities. Typical application areas include:
These applications represent common industry uses of FRP composite panels. Actual suitability depends on load requirements, environmental exposure, and applicable building codes.
Several variables should be evaluated when specifying a fiberglass hollow core panel:
Mechanical properties and load ratings are configuration dependent and must be verified for the selected panel specification.
The table below lists general product attributes. Specific values, dimensions, and performance characteristics are configuration dependent and should be confirmed for the intended application.

What is the weight of fiberglass hollow core panels compared to solid FRP panels?
Hollow core panels are generally lighter than solid FRP panels of equivalent thickness. Actual weight depends on cross-section design, wall thickness, and panel dimensions. Weight per unit area should be confirmed for the selected specification.
Can these panels be used for outdoor applications?
FRP panels can be used outdoors when the resin system and surface treatment are selected for UV exposure. Weathering performance depends on the specific resin formulation and protective coatings applied.
Are custom sizes and cross-sections available?
Panel dimensions and cross-section configurations can be customized based on project requirements. Custom configurations are subject to order review and manufacturing feasibility.
How are the panels installed?
Installation methods depend on the application and supporting structure. Panels may be mechanically fastened, set into framing systems, or joined using compatible adhesives. Edge sealing may be required in certain environments. Installation details should be confirmed for the specific project.
Are fiberglass hollow core panels fire resistant?
Fire performance depends on the resin system and panel construction. Flame-retardant resin formulations may be available for projects with specific fire rating requirements. Compliance with fire safety standards should be evaluated for the intended application.
