Product Overview
Fiberglass decking plank is an FRP/GRP composite decking component produced by the pultrusion process. The top surface and support legs are formed as one integral part. It is made from fiberglass reinforcement and a thermoset resin system. The plank is available with a smooth surface or an anti-slip grit surface. Panels are laid with a male-female connection for tight assembly. Typical applications include pedestrian bridges, cycle bridges, marinas, tank platforms, trench covers, and vehicle trailer decks.
Product Definition
A fiberglass decking plank is a pultruded FRP decking element designed to replace deteriorating wood in industrial and outdoor structures. The plank is produced by pulling continuous glass fiber reinforcement through a thermoset resin bath and heated die, resulting in a profile in which the top surface and legs are formed as one continuous part. It is supplied in project-specified lengths and widths, with color options available upon request.
Key Product Facts

- Color options: commonly available colors; custom colors may be available upon request
Material & Construction
The decking plank is produced by the pultrusion process. Continuous fiberglass rovings and mats are impregnated with a thermoset resin system, then pulled through a heated die to form the plank profile. The top surface and supporting legs are formed as one continuous part, eliminating the need for secondary bonding between surface and support. The edge profile includes a male-female connection, allowing adjacent planks to be laid tightly against each other.
Surface finish is available in two forms: a smooth surface for general use, or an anti-slip grit surface for areas where traction is needed. The anti-slip grit is incorporated into the surface during production, not applied as a separate coating.
Field cutting or drilling of the plank 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
Fiberglass decking planks are commonly used in environments where traditional wood decking deteriorates or where corrosion resistance, electrical insulation, or low maintenance are important. Typical applications include:
- Pedestrian bridges and cycle bridges
- Marinas and waterfront structures
- Tank platforms and access decks
- Trench covers and cable covers
- Vehicle trailer decks
- Cooling tower floors and platforms
- Bridge sidewalks and light-traffic decking
- Agricultural structures and light railcar platforms
These applications reflect general industry usage of FRP decking planks. Actual suitability for a specific project depends on load requirements, span, chemical exposure, and installation conditions.
Load Capacity
No standard or published load capacity values are provided for this product. The allowable load for any given plank configuration depends on:
- Plank width and thickness
- Span between supports
- Resin system and temperature effects
- Type and frequency of traffic
- Support conditions and fastening method
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, plank dimensions, or support arrangements.
Selection Considerations
When selecting a fiberglass decking plank, the following variables should be evaluated based on project-specific conditions:
- Load requirements: Load capacity depends on plank width, thickness, span between supports, and the type of traffic. Provide the expected load and support spacing for accurate sizing.
- Surface finish: Choose smooth finish for general applications or anti-slip grit finish for wet, oily, or high-traffic areas.
- Resin system: The specific thermoset resin can be selected based on the chemical environment. Provide chemical exposure details for resin recommendation.
- Color: Color options may be available depending on resin system and production feasibility. Specify color preference during inquiry.
- Installation and connection: Planks are laid with a male-female connection. Ensure the supporting structure and fastening method match the plank profile.
- Field modification: Cutting or drilling the plank may expose glass fibers and affect corrosion resistance. Any field modifications should be sealed with compatible resin.

Reference to any standard does not imply certification or compliance unless explicitly stated in project documentation. The specific standard edition, test conditions, and acceptance criteria are determined by the project's governing code and specifications.
Frequently Asked Questions
How is the anti-slip surface applied?
The anti-slip grit surface is incorporated during production. It is not a separate coating. The surface texture is formed as part of the manufacturing process.
Can these planks be cut on-site?
Field cutting is possible using appropriate cutting tools. Cutting may expose glass fibers, so the cut edges should be sealed with compatible resin to maintain corrosion resistance.
How are the planks connected to each other?
The planks use a male-female edge connection. Adjacent planks are laid tightly against each other, forming a continuous deck surface.
Are custom sizes and colors available?
Custom dimensions and colors may be available based on project requirements and production feasibility. Provide the required size and color preference during inquiry.
Is the material suitable for electrical or magnetic environments?
FRP is non-conductive and non-magnetic. These properties can be beneficial in electrical installations or areas with magnetic sensitivity. For specific dielectric requirements, confirm with the engineering team.
