Trex Composite decking board types and fasteners

Grooved Boards

Trex grooved board

The grooved decking boards are a versatile solution for decking projects, offering a secure and efficient installation process. These boards feature precisely machined grooves along the sides, allowing for a hidden fastening system. This not only enhances the deck’s appearance by concealing screws but also ensures a smooth, splinter-free surface. Grooved boards are particularly popular for their ease of installation. They are an excellent choice for DIY enthusiasts or professionals looking to streamline the deck-building process while maintaining a polished and sleek appearance.

Square Edge Boards

These decking boards lack the grooves found on their counterparts, making them ideal for surface fixing. Square edge boards offer a classic, unembellished appearance, perfect for achieving a clean, timeless deck design.  They can be used as breaker boards,  fascia boards or step treads.. They create a smooth blemish free deck surface with a natural wood grain pattern  when used with countersunk screws and colour-matched plugs.

Fascia Boards

Trex fascia board

The fascia boards serve a crucial role in deck construction by providing a polished finishing touch to the deck’s perimeter. These boards are designed to cover and protect the structural elements of the deck, such as the joists and framing. They offer a clean, seamless appearance, concealing the underlying structure and ensuring a cohesive, professional look. Trex fascia boards are available in various colours, allowing homeowners to coordinate them with their deck’s surface for a unified and aesthetically pleasing outdoor space

Trex decking fasteners

Trex hidden fasteners

Trex Hidden Fasteners represent a crucial element in the evolution of modern deck construction, offering a seamless and aesthetically pleasing alternative to traditional visible fastening methods. These hidden fasteners are designed to discreetly secure deck boards without the need for exposed screws or nails. The system typically involves a set of specially crafted clips placed between deck boards, creating a clean, unblemished surface. Beyond the enhanced visual appeal, Trex Hidden Fasteners contribute to the overall structural integrity of the deck by promoting even spacing and minimising the risk of warping or cupping. This innovative fastening solution streamlines the installation process and ensures a smooth, barefoot-friendly deck surface

Frequently Asked Questions

While a Trex deck is typically more expensive than a hardwood timber deck such as spotted gum (expect to pay 20% to 30% more for Trex deck boards than kiln-dried hardwood), the savings achieved by not having  to sand and oil the boards will be in the thousands of dollars each year.

A Trex deck board costs $29.07 a linear metre/$207.55 a square metre. Random length Spotted Gum deck boards are $18.37 a linear metre/$136 a square metre. Prices do change, so check with your local retailer for current prices.

Trex  decking is made up of 95% recycled materials, including:

  • Timber
  • Sawdust
  • Wood grain fillers
  • Everyday household items (toilet paper, newspapers, shopping bags etc.)

Trex decking boards are constructed with a protective shell with rich colours engineered into the design. This means no painting or staining and up to 25 years of stunning colour.

Trex has created products that stand the test of time, as well as the difficulty of aesthetic style, with a range of beautifully crafted products.

All composite and natural timber materials will absorb heat and get hot on scorching days, and Trex decking materials are no exception. Trex decking boards are generally a little hotter than timber – but you won’t be able to tell the difference on a hot day.

The darker the board’s colour, the more heat it will usually absorb. If your deck is in direct sunlight, you can choose a lighter colour, as darker-coloured boards will generally be hotter to the touch. Alternatively, if your deck has a pergola or awning over it, you can choose whatever colour you think best suits your area, as heating up won’t be an issue.

Trex decking materials are an excellent choice for a pool deck. Not only is a Trex deck suited to our harsh Australian climate, but Trex deck boards also easily handle the wet conditions around your pool.

It won’t rot or warp and will give you many years of hassle-free service. Wash your deck with warm water and a broom every month or so, and it will look just as sparkling and fresh as the day it was installed.

Trex uses especially designed patented clips – Hideaway Fasteners – that slide into the groove on the side of the deck board. The clip is screwed into the substructure, leaving a smooth, uncluttered look and feel to the top of the deck.

Trex deck boards are rated to BAL level 29

What are the disadvantages of Trex Composite Decking?
  1. Cost: Trex  Decking tends to be more expensive upfront than traditional wood decking. While it can be cost-effective over time due to low maintenance requirements, the initial investment can be a barrier for some homeowners.
  2. Heat Retention: Trex decking can become hot under direct sunlight, especially in warmer climates. This can make walking on bare feet uncomfortable and may require rugs or other coverings to mitigate the heat. If your deck does not have cover and is in direct sunlight, it’s a good idea to choose a lighter colour rather than a dark one. The new range – Trex Lineage has been engineered to be significantly cooler than most other composites available on the Australian market.
  3. Expansion and Contraction: Trex Transcend decking can expand and contract with temperature fluctuations like many othe materials. This may lead to slight gapping of boards over time. Proper installation and spacing by a professional installer will mitigate this issue so that your deck looks perfect all the time.
