GRP Composite Flat Sheet & Anti Slip Products
DecPlate strips have been developed due to increasing demand for a retro fitted anti-slip product to solve the problem of worn, wet or algae covered wooden decking boards.
These strips are available in a 2 or 3mm option, in any colour and with a fine grit profile.
Supplied in various widths or lengths DecPlate is easily fitted using a grab adhesive or screws.
Anti-Slip Decking
GRP Decking Strips provide a safe, robust solution to minimising the potential for slips on areas covered with moss or algae and on low traction surfaces.
Decking strips are a bespoke product made to required sizes and to any BS or RAL colour. Strips are easily fitted using a simple “glue and screw” method and can be fixed to a wide range of substrates including concrete, timber, asphalt etc.
Strips have excellent U.V. resistance so are not prone to fading after prolonged exposure to sunlight. Strips are easily cleaned using a stiff bristle brush, or for more stubborn markings, can be pressure washed on a low setting.

Installation Guide
Each installation will have its own criteria but there are a number of operations and procedures that are applicable in all circumstances. Therefore we have made available for download as a PDF our “Guide to Installing GritPlate“.

After researching many forms of grit, Smyth Composites elected to use Fused Alumina due to its superior qualities and suitability for the anti-slip applications. Other types such as Bauxite or Quartz are available by special order. The Fused Alumina is available in a variety of grades:
Ultra-Fine (Barefoot), Fine, Medium, Coarse, Ultra-Coarse |
Panel Size and Thickness
Panels can be manufactured to any length but with a width restriction of 1500mm. Standard product range can be manufactured to literally any thickness from 2mm upward. As this is a handmade product, containing various raw materials, tolerances apply to both size and thickness which may vary depending on the specifications ordered. Occasionally we can accommodate “oversized specials” – please contact us for details.

Thermal Conductivity: 0.2w/mKTensile Strength: 123MPaTensile Modulus: 7.1GPaGRP is 7 times stronger than mild steel |
Flexural Strength: 193 MPaAs standard, we used chopped-strand fiberglass… Flexural Strength can be enhanced by the addition of woven reinforcement if required. |
Colour Range
Black, Grey (RAL 7001) and Yellow (08 E 51) colour as a standard. However, panels can be manufactured to any non-metallic coded colour from the following ranges:
A Colour Matching Service is also available.

Thermal Co-Efficient of Expansion: 30 x 10^ (-6)Deg C
Compared with many other plastics GRP has minimal expansion and contraction characteristics and will not bow or warp in extreme temperatures.
