Heavy-Duty Micro Mesh GRP Decking for Marine Environments
Micro Mesh GRP Marina Decking features an 8mm × 8mm open mesh design combined with a gritted anti-slip surface, providing enhanced underfoot comfort and maximum slip resistance in demanding marine environments. Designed for applications where smaller apertures are required, micro mesh decking helps prevent small objects from falling through while maintaining excellent drainage and light penetration.
Engineered for strength, durability, and long-term performance, micro mesh GRP decking is ideal for pontoons, marina walkways, access gangways, and pedestrian platforms exposed to constant moisture, saltwater, and heavy foot traffic.
The following load performance data shows the unsupported span capacity of micro mesh GRP marina decking across various thicknesses. Figures are provided for both point load and uniformly distributed load (UDL) scenarios, helping engineers and specifiers select the correct panel depth for pedestrian and heavy-duty marine applications.

Micro Mesh GRP Marina Decking (8mm × 8mm) FAQs
Micro mesh GRP marina decking features an 8mm × 8mm open mesh with a gritted anti-slip surface, designed to provide enhanced underfoot comfort, excellent slip resistance, and long-term durability in marine environments.
It is commonly used on pontoons, marina walkways, access gangways, pedestrian platforms, jetties, and leisure decking where smaller apertures and improved object retention are required.
Yes. The gritted surface is tested to 1.04 CoF (BS 4592-0), offering excellent slip resistance in wet, oily, and icy conditions.
Micro mesh GRP decking is typically available in 22mm and 30mm thicknesses, allowing it to be specified for both standard pedestrian and heavier-duty marine applications.
Micro mesh decking offers an excellent strength-to-weight ratio, with published point load and uniformly distributed load (UDL) data to support accurate specification for unsupported spans.
Yes. The open mesh design allows effective drainage and light penetration, helping to reduce surface water while supporting marine ecosystems below.
Absolutely. GRP decking requires no painting, sealing, or treatment and will not rot, rust, or corrode, even in harsh saltwater environments.
Yes. GRP is non-conductive and offers high electrical resistance, making it suitable for marina environments where electrical safety is important.
