Fiberglass Hollow Core Panel Overview
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.
Product Definition
Fiberglass hollow core panel is a composite panel composed of fiberglass reinforced plastic (FRP/GRP), featuring 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 project-specified dimensions for use in flooring, cladding, platforms, and modular systems.
Key Product Facts
- Material: glass fiber reinforcement with thermosetting resin matrix
- Panel structure: internal hollow core cross-section that reduces weight while maintaining rigidity
- Surface finish: smooth or textured, depending on application requirements
- All panel dimensions, resin systems, and core configurations are project-specified; no default configuration applies
- FRP is generally non-conductive; actual electrical properties vary with resin system and additives
Material & Construction
The panel is composed of glass fiber reinforcement embedded in 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. Resin options commonly include polyester and vinyl ester, depending on project requirements. Flame-retardant resin formulations may be supplied for applications requiring specific fire performance. If fire performance is a project requirement, indicate the relevant standard during inquiry so that the appropriate resin system can be selected.
The panel surface can be supplied with a smooth or textured finish, depending on application requirements. Custom dimensions and cross-sections may be available subject to production capabilities.
Field cutting or drilling of FRP panels may expose glass fibers and affect corrosion resistance. Any field modifications should be sealed with a compatible resin to maintain protective properties. Performance in mixed chemical environments or cycling temperatures should be evaluated based on actual project conditions.
Applications
FRP hollow core panels are commonly used in environments where lightweight construction and corrosion resistance are priorities. Typical application areas include:
- Industrial flooring and platform systems
- Building cladding and modular construction
- Marine and offshore structures
- Chemical processing facilities
- Transportation and infrastructure components
These applications represent common industry uses of FRP composite panels. Actual suitability depends on load requirements, environmental exposure, and applicable building codes.
Load Capacity
No standard or published load capacity values are provided for this product. The allowable load for any given panel configuration depends on:
- Panel thickness and wall dimensions
- Hollow core configuration and internal channel geometry
- Span between supports and support conditions
- Resin system and temperature effects
- Fastening method and edge support details
Any load values presented in project documentation apply only to the analyzed configuration and the governing design conditions. Results from one project should not be extrapolated to different spans, panel thicknesses, or core configurations.
Selection Considerations
Several variables should be evaluated when specifying a fiberglass hollow core panel:
- Panel dimensions and span: Selected based on expected load and support spacing.
- Hollow core configuration: Internal channel size and wall thickness affect panel weight, stiffness, and insulation properties.
- Resin system: Determines chemical resistance, UV stability, and service temperature range.
- Surface finish: Smooth or textured surface selected for slip resistance, cleanability, or aesthetic requirements.
- Edge details: Panel edges may require sealing or framing depending on the application and exposure conditions.
Mechanical properties and load ratings are configuration dependent and must be verified for the selected panel specification. Structural calculations are required for specific applications.

Frequently Asked Questions
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 may be customizable based on project requirements. Custom configurations are subject to order review and production 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.
