Marine dock decking panels are anti-slip FRP grating and solid-top panel systems engineered for docks, marinas, jetties, and offshore platforms exposed to constant saltwater moisture. The panels use fiberglass reinforced plastic (FRP) with isophthalic polyester or vinyl ester resin systems, forming a chemically inert barrier resistant to chloride penetration under ISO 12944 category C5-M conditions.
The gritted anti-slip surface delivers coefficient of friction of 1.04 per BS 4592-0, ensuring safe pedestrian traffic in wet, oily, and icy conditions. Standard mesh sizes include 25×25mm, 38×38mm, and 50×50mm, with mini-mesh at 13×38mm and micro-mesh at 8×8mm for high-traffic areas preventing small objects from falling through the deck.
Standard panel sizes are 1220×3660mm and 1000×2000mm, with depths of 25mm, 38mm, 50mm, and 75mm for varying load requirements. At density of approximately 1.8 g/cm³, FRP decking weighs only 13-26 kg/m² compared to 48 kg/m² for equivalent steel grating, reducing installation labor and structural support demands.
These dock decking panels serve marina walkways, pontoons, access gangways, pedestrian platforms, and offshore accommodation modules. They achieve Class A fire resistance per ASTM E84 with flame spread index of 25 or less, water absorption of 0.45% over 24 hours per ASTM D570, and reliable performance from -100°C to +200°C.

Marine Dock Decking Panel Buying Guide & FAQ
Selecting the right marine dock decking panel requires understanding slip resistance, corrosion performance, load capacity, and fire rating. This guide answers the most common questions from marina operators, port engineers, and offshore contractors evaluating FRP grating and solid-top panels for saltwater infrastructure exposed to constant moisture.
1. What is the difference between molded and pultruded FRP grating?
Molded FRP grating is produced by laying continuous bi-directional E-glass roving in a mold impregnated with resin, creating a monolithic one-piece panel with equal strength in both directions. Pultruded grating uses drawn bars assembled with cross rods, offering higher unidirectional strength for long spans. Molded grating suits irregular cuts, while pultruded grating fits straight walkway runs.
2. What mesh size and depth do I need for my dock?
Standard 38×38mm mesh at 38mm depth suits most marina walkways with pedestrian traffic. High-traffic areas use mini-mesh at 13×38mm to prevent small objects from falling through and allow smooth movement of trolleys and wheelchairs. For vehicle traffic or heavy equipment loads, 50mm depth with 50×50mm mesh provides the necessary load capacity over longer unsupported spans.
3. How does FRP decking outperform steel in saltwater environments?
FRP resists corrosion through its material composition rather than a surface coating, using isophthalic polyester or vinyl ester resin systems that chlorides cannot penetrate. Steel grating in ISO 12944 category C5-M marine environments typically fails within 7 to 10 years, while FRP decking routinely delivers 25+ years of service with zero repainting and near-zero maintenance.
4. What slip resistance do gritted surfaces provide in wet conditions?
Gritted anti-slip surfaces achieve coefficient of friction of 1.04 per BS 4592-0, tested for wet, oily, and icy conditions. This exceeds R11 to R13 ratings per DIN 51130, making FRP dock decking one of the safest surfaces for coastal and lake environments. The grit is integrally bonded during molding to prevent dislodging under heavy foot traffic.
5. Which fire ratings apply to marine dock decking?
FRP grating achieves Class A fire resistance per ASTM E84 with flame spread index of 25 or less for vinyl ester and fire-retardant grades. This meets the fire safety requirements of offshore platforms and marine infrastructure. The material is also electrically non-conductive, eliminating galvanic corrosion at contact points between dissimilar metals in hybrid dock structures.
