Our fiberglass decking is made from fiberglass-reinforced plastic (FRP) and offers a durable alternative to traditional decking materials. Each panel combines glass fiber reinforcements with thermoset resins (polyester, vinyl ester, or phenolic), making it suitable for environments where moisture, corrosion, and heavy use are concerns. Unlike wood that rots or traditional composites that degrade, fiberglass decking resists moisture, rot, and insects and can provide long service life in harsh conditions. It requires only occasional cleaning, avoiding the frequent sanding, staining, and sealing that wood often needs. Our fiberglass decking has textured, slip-resistant surfaces that provide good traction when wet. The material resists moisture, insects, and UV degradation, which are common causes of premature deck failure.
| Key Feature | Real-World Benefit |
|---|---|
| Moisture Resistance | Low water absorption helps prevent rot and structural weakening |
| UV Stability | Maintains color and strength well in outdoor use |
| Chemical Resistance | Resists pool chemicals, salt spray, and household cleaners |
| Thermal Stability | Lower expansion and contraction than many PVC composites |
| Lightweight Design | Typically much lighter than concrete and lighter than many hardwoods for equivalent deck thickness |

Common Applications
Residential Uses
- Backyard Decks: Create durable outdoor living spaces
- Pool Surrounds: Slip-resistant surface resists chlorine damage
- Rooftop Terraces: Lightweight construction can reduce structural requirements compared to concrete
Marine & Waterfront
- Docks & Marinas: Maintains integrity despite constant water exposure and salt spray
- Boardwalks: Withstands environmental extremes while providing safe pedestrian surfaces
- Waterfront Properties: Resists the corrosive effects of salt air better than many standard deck materials
Specialized Applications
- Commercial Walkways: Handles heavy foot traffic with minimal wear
- Industrial Platforms: Provides safe working surfaces in challenging environments
- Cooling Tower Decks: Resists the highly corrosive conditions that quickly degrade other materials

Frequently Asked Questions
How does fiberglass decking compare to traditional wood or composite decking?
Fiberglass decking generally offers better durability in wet and corrosive environments than pressure-treated lumber and standard composites. Lifecycle costs depend on maintenance, climate, and project size. Contact us for a project-specific comparison.
What makes fiberglass decking ideal for wet environments?
Unlike wood or wood-plastic composites that absorb moisture, fiberglass decking has low water absorption. This property, combined with its corrosion resistance, makes it suitable for wet environments.
How difficult is fiberglass decking to install?
Most contractors familiar with standard decking can easily install fiberglass decking using common tools. The material can be cut with circular saws fitted with masonry or diamond blades. Our panels come with comprehensive installation guides, and many feature interlocking systems that simplify alignment and attachment to substructures.
What surface options are available for fiberglass decking?
We offer multiple surface textures to meet specific needs:
- Fine-grit surfaces for residential applications (balancing comfort and safety)
- Coarse-grit surfaces for high-traffic or wet areas (maximum slip resistance)
- ADA-compliant textures for commercial and public installations
- Smooth surfaces for specific non-pedestrian applications
How does extreme weather affect fiberglass decking?
With a thermal expansion coefficient of 4.7 × 10⁻⁶ in/in/°F, fiberglass decking experiences less expansion and contraction than many alternative materials. It remains suitable for use from -40°F to 180°F, making it a good choice for locations with temperature variations. It also stays relatively cool in direct sunlight compared with metal decking.
What load capacity can fiberglass decking support?
Our standard residential panels can support concentrated loads up to 300 lbs with a 6× safety factor at 24″ spans. For commercial applications, we offer heavy-duty panels designed for uniform loads up to 150 psf with appropriate joist spacing. Custom high-load panels are available for specialized industrial applications.
