Slip-Resistant Open Mesh GRP Decking for Marine Use
Our Mini and Micro Open Mesh Marina Decking systems provide industry-leading slip resistance and durability for marine and leisure environments. Manufactured from high-quality GRP (Glass Reinforced Plastic) with a gritted anti-slip surface, these panels are engineered to perform in harsh conditions while maintaining pedestrian safety in wet, oily, or icy environments.
The Micro Mesh (8mm × 8mm) option is ideal where very small openings are required for enhanced underfoot comfort and object retention, while the Mini Mesh (12mm × 12mm) offers an excellent strength-to-weight ratio and versatility across a wide range of marina and pontoon applications.
