Antislip Plus®

Anti-slip timber decking available in either a castellated or smooth profile. It has been specifically designed to provide a durable and effective external anti-slip surface to minimize any risk of slipping, even in adverse weather.

It uses a unique formula of resin based aggregate inserts which are injected into the deck board grooves. If smooth boards are required, grooves are specifically machined into the boards to receive the inserts.

Feature and benefits:

  • Strength classes C16 or C24, and CE marked.
  • Exceeds the Health and Safety Laboratory’s (HSL’s) anti-slip testing guidelines.
  • Easy to clean and maintain.
  • Full FSC® and PEFC™ chain of custody.
  • Deckmark+ accredited from TDCA.
  • Manufactured in accordance with BS 5268.


Suitable for all decks where there is public access or where there is an anticipated high level of pedestrian traffic. Antislip Plus® is also recommended for all stairs and ramps.
