Micro Mesh Load Data (8mm)

The load capacity data below shows the performance of GRPGS micro mesh GRP marina decking panels when installed over unsupported spans. Figures are provided for both point load and uniformly distributed load (UDL) scenarios to support accurate specification in marine and high-traffic environments.

Load Capacities

Unsupported Span (unfixed) over a 1m length
Panel Thickness Weight kg/m2 Load Type 300mm 500mm 600mm 750mm 1000mm 1200mm 1500mm
22mm 15kg Point Load 1006kg 362kg 251kg 161kg 91kg 63kg 40kg
UDL 2164kg 1220kg 706kg 361kg 153kg 88kg 45kg
30mm 20kg Point Load 2049kg 972kg 675kg 432kg 243kg 169kg 108kg
UDL 4261kg 2557kg 1896kg 971kg 410kg 237kg 121kg
All values are based on a 1% deflection limit and are intended as guidance only. Final panel selection should be confirmed against project-specific loading and structural requirements.

Features of Micro Mesh GRP
Marina Decking (8mm × 8mm)

  • Anti-slip surface – Gritted finish tested to 1.04 CoF (BS 4592-0) for maximum pedestrian safety in wet, oily, and icy conditions.
  • Electrical insulation – Voltage breakdown of 18kV/mm (ASTM D149), suitable for marine and industrial environments.
  • High structural density – GRP composition with a specific gravity of 2100 kg/m³ (ISO 9001 certified).
  • Thermal stability – Low expansion factor of 13 × 10−6 mm/mm (ISO 9001).
  • Low water absorption – Just 0.45% over 24 hours (ASTM D570), ideal for constant exposure to moisture and saltwater.
  • Wide operating temperature range – Reliable performance from -100°C to +200°C.
  • Fire resistance – Achieves Class 2 flammability rating.
  • Frost & weather resistance – Tested to MOAT 22, suitable for harsh marine environments.

Micro Open Mesh GRP Marina Deck Load Data FAQs

How should GRP marina deck load data be interpreted?

Load data provides guidance on how GRP marina deck panels perform when loads are applied across different unsupported span lengths. It should be used to compare panel thicknesses and assess suitability for specific applications, rather than as a final design approval.

What does 1% deflection mean in load testing?

A 1% deflection means the panel has deflected by 1% of the span length under the applied load. This is a commonly used benchmark to indicate performance at a controlled and acceptable level of movement for pedestrian decking applications.

Yes. Load data should always be confirmed against project-specific requirements by a qualified engineer or specifier, taking into account fixing methods, support conditions, traffic type, and site environment.
