What is composite decking?

Manufactured from a combination of recycled plastics, reclaimed wood fibre, resins and ploymers, composite decking not only mimics the grains and colours of traditional timber, its benefits make it a popular alternative to timber decking.

Composite decking has come a long way since it became popular in the 1990s; current offerings closely resemble timber deck materials and offer many additional benefits.

benefits of composite decking:

  • Low maintenance – Compared to a traditional timber, it is very easy to clean and maintain. Not only is it very durable, being able to withstand tough conditions, but the only maintenance it needs is a regular cleaning with soapy water – oiling is not required.

  • Modern design – Our timber decking alternatives take on the appearance of a wide range of wood styles, so you can customise your decking to suit the design of your outdoor space.

  • Less expensive – Composite is less expensive over the lifespan when comparing with traditional timber.

  • Built to last – We are so confident that our decks will last and won’t fade, that we guarantee it with performance warranties ranging from 10 to 25 years.

  • Safe – Does not split or splinter, making it a solid option for bare feet. Many options are also water tolerant and slip-resistant and are perfect to use around a home pool or spa.

  • Eco-friendly – 95% of the materials used to produce composite are either recycled plastic or reclaimed wood. By choosing composite decking, you are preventing hundreds of thousands of tons of waste from entering landfills each year.

  • Easy to install – Boards are manufactured with a groove system with special fixings, making installation a very easy process. No nails are required to install it and most people find installation much easier than timber decking installation.

  • Durable – Composite timber is designed to stand up to the Australia’s harsh conditions. It handles heat, UV exposure, rain, moisture, and pests without staining, fading, or scratching.
