Anti-Slip GRP Encapsulated Plywood Panels
GRP encapsulated plywood panels combine the structural strength of WPB plywood with the durability, moisture resistance and slip resistance of a fully bonded GRP outer layer. The encapsulation process seals all faces and edges of the panel, helping to prevent water ingress, swelling and deterioration that can occur with untreated plywood products.
The panels are widely used for access walkways, platforms, ramps, service areas, transport infrastructure and industrial flooring applications where a lightweight, rigid and anti-slip panel system is required.
Available in a range of thicknesses, colours and grit finishes, panels can be supplied in standard sheet sizes or fabricated to project-specific dimensions with cut-outs, penetrations and fixing details where required.

| Weight | Up to 40% lighter than equivalent solid GRP sheet constructions |
| Moisture Resistance | Fully sealed faces and edges help prevent water ingress |
| Colours | Standard and BS/RAL colours available |
| Fire Performance | Fire-retardant options available |
| Fabrication | Cut-outs, penetrations and fixing holes available |
| Typical Thicknesses | From 9mm plywood core upwards |
| Typical Applications | Walkways, ramps, platforms, service areas and industrial flooring |
Moisture Resistance & Lightweight Construction
Unlike untreated plywood, GRP encapsulated panels are sealed on all faces and edges to help prevent moisture ingress and long-term deterioration. The combination of a plywood core and GRP outer skin provides a lightweight but rigid panel that is easier to handle and install than many solid GRP alternatives.
The anti-slip gritted surface improves underfoot traction while maintaining the structural performance required for access systems, platforms and industrial flooring applications.

Typical Applications Of Gritted Encapsulated Plywood Panels
GRP encapsulated plywood panels are commonly used for access walkways, service platforms, ramps, transport infrastructure, industrial flooring systems and maintenance access routes. Their lightweight construction, moisture resistance and anti-slip surface make them particularly suitable for external environments and refurbishment projects where traditional plywood products may be vulnerable to water ingress or premature deterioration.
The panels are also frequently specified where custom fabrication, cut-outs and project-specific dimensions are required.
Gritted Encapsulated Plywood Panels — FAQs
Encapsulated plywood panels are WPB plywood sheets fully coated in GRP, including all edges, to create a waterproof, anti-slip and highly durable composite panel.
Yes. Every face and edge is sealed with GRP, preventing moisture penetration, rot and swelling.
They are typically up to 40% lighter than solid GRP sheets of equivalent thickness.
Fine and Medium grit finishes are available depending on the slip-resistance required.
Absolutely — they are specifically designed for wet, harsh, corrosive or high-traffic environments.
Yes. We can supply cut-outs, penetrations, drilled holes, rakes or notches to match your installation layout.
Yes. Any BS or RAL colour can be supplied, including high-vis or safety-zone colours.
Yes — fire-retardant encapsulated plywood panels can be manufactured on request.
