Grad Deck System – Kebony


Decking system with Kebony timber boards on hidden fixing support rails and height adjustable pedestals.

Features and benefits:

  • Fixings are completely hidden, even between the boards.
  • Includes fast-fit clips, which cannot be dislodged once fitted.
  • Attractive appearance.
  • Support rails have industrial strength.
  • Boards can be removed with no damage (using specific tools - consult manufacturer for details).
  • Space-saving - can be installed to lower heights than traditional decking.
  • A matching cladding system is available - consult manufacturer for details.
  • Boards are free from grooves, with a convex surface – this prevents ‘cupping’ of the timber and eliminates water from pooling.
  • Quick, efficient installation - almost twice as fast as traditional methods.
  • Comes with a 30 year warranty.
  • Pedestal-based build-up height is from 64 mm.
  • Boards are FSC® certified.

Kebonised timber:

Formed via a process which enhances the properties of softwood by injection with a toxin free formula. The wood is subjected to both vacuum and pressure to ensure complete absorption of the treatment - it is then dried, before being cured at high temperature. The process permanently modifies the wood cell walls, giving Kebony hardwood characteristics and a rich brown colour. It is:

  • Environmentally friendly.
  • Sustainable and durable.
  • Easy to maintain (just requires normal cleaning).

May develop a natural silver-grey patina if left to weather in the sun (without UV protectant oils).
