Micro Mesh GRP Marina Decking Specification
The 8mm × 8mm Micro Mesh configuration creates a more enclosed grating surface than the 12mm × 12mm Mini Open Mesh range. It is available in 22mm and 30mm panel depths, with panel sizes including 3m × 1m, 4m × 1.2m and 4m × 1.5m.
The gritted surface provides additional slip resistance in wet conditions, while the open construction allows water to pass through the decking. Panel depth should be selected according to the required loading, unsupported span and installation arrangement.
The load data below shows point load and uniformly distributed load (UDL) guidance for 22mm and 30mm Micro Mesh panels across a range of unsupported spans. Values are based on a 1% deflection limit and should be checked against the loading and structural requirements of the project.

Micro Mesh Compared with Mini Open Mesh
Micro Mesh uses an 8mm × 8mm open hole, compared with the 12mm × 12mm opening used on Mini Open Mesh. The smaller aperture creates a more enclosed grating surface. Panel depth should still be selected according to the required unsupported span, loading, supporting structure and installation requirements.
Micro Mesh GRP Marina Decking (8mm × 8mm) FAQs
Provide the required panel dimensions, support centres and anticipated loading, together with details of the supporting structure. Any cut-outs, openings or other fabrication requirements should also be identified before the panels are prepared.
Yes. Micro Mesh panels can be cut and fabricated to suit project dimensions, including requirements around existing structures and openings. Accurate dimensions should be provided before fabrication so the panels can be prepared for the installation.
It can be installed onto a suitable existing structure, subject to the condition and arrangement of the supports. Support centres, anticipated loading and the proposed fixing arrangement should be checked before the panels are specified.
The fixing arrangement depends on the supporting structure and installation requirements. Stainless steel fixings are available for GRP decking in marine applications, with the appropriate fixing selected according to the panel and supporting structure.
Cut panels still need to be adequately supported and fixed as part of the completed installation. The final panel dimensions, cut edges, support positions and any openings should therefore be considered when planning the fabrication and supporting structure.
Yes. Panels can be fabricated with openings and cut-outs where required by the installation. Their position and dimensions should be established before fabrication, with the surrounding support arrangement considered where necessary.
