Is Trex decking the Same as Composite?

Yes and no.

Trex decking is the most well-known composite material available, contributing to roughly 40% of the world’s combined market. Just as Starbucks Coffee isn’t the only takeaway coffee shop on the market, but it is the market leader, Trex is the leading provider of composite deck materials.

While composite boards get recognition (and rightfully so) for their low maintenance finish, a wide range of colours, and environmentally-friendly make-up, get plenty of samples before you decide which board to invest in.

Frequently Asked Questions

How much do Trex decking composite materials cost?

As with most things in life, you get what you pay for.

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 composite deck boards than kiln-dried hardwood), you end up on the right side of the ledger in the long run.

Trex Transcend boards are available in 3 lengths. Each board is 14 centimetres wide and 2.5 centimetres thick.
4.88 metres – $141.90 per board ($29.07 a linear metre)
5.48 metres – $159.50 per board ($29.07 a linear metre)
6.10  metres – $177.10 per board ($29.07 a linear metre)

Fasteners are an additional cost. The most common and best fastener is the Trex-patented Hideaway Fastener. These are about 59 cents each; you need just over three per linear metre of board.


Call us on 0413 185 735 for more For more information on Trex decking Installation and we will happy to answer any questions you may have.

How do trex decking prices compare to hardwood decking prices?

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 (A pack will contain lengths ranging from 1.00 metre to 5.4 metres in length) and will take longer to cut and install.

A composite board is quicker to install and doesn’t have hardwood’s annual maintenance costs. Maintenance costs with a reputable firm will usually be $60 – $80 an sq metre per year. That adds up to high maintenance costs over the life of your deck. Think sanding, acid washing, and oiling.

Considering that the average Sydney deck is between 30 square and 40 square metres, a quick look at your calculator and some maths will show you how much it can cost to maintain a traditional hardwood Australian deck.

For instance, take a 35 sq metre deck that might need some sanding and is acid-washed and stained once a year over ten years.

35 sq metres x $60 a sq metre x 10 years = $21,000

That is a considerable amount of money to spend on maintenance. If you outlay a little more on the initial purchase, you save yourself all the ongoing maintenance costs over the ten years in the example above.

It’s true that the Trex decking range typically costs more than traditional hardwood timber decking – but as you can see, there’s more to the story than the upfront price.

Although Trex decking boards are made from recycled materials, processing these materials and ensuring high performance and strength adds to your upfront costs. But keep in mind that your deck will be your social hub and personal oasis for decades to come, and that’s where the savings kick in – no expensive maintenance for the life of your deck.

What is Trex decking made from?

Trex decking products may look like elegant, modern timber… but it’s a different story inside. Trex is made up of 95% recycled materials, including:

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

Even better, the composition of Trex decking offers natural resistance to stains and scratches. So whether it’s a glass of red wine, natural weathering, or outdoor furniture, Trex decking is designed to look fabulous no matter what’s thrown at it.

When you value the state of your home as much as the state of the planet, it’s nice to know the Trex Corporation has never cut down a single tree. Trex Composite Decking offers a range of sustainable decking options for your home using unwanted timber from woodworking projects and recyclable materials.

Trex is the first company in the timber-alternative decking industry to receive an International Code Council Evaluation Service® (ICC-ES)* SAVE Verification for Recycled Content. This independent third-party verification confirms that, with a minimum of 95.4% recycled content, Trex recycled composite decking products are as green as possible.

Not only will you have a deck board that reproduces the stunning appearance of timber, but you’ll be playing your part to help the environment. By using alternative materials (while still delivering the timeless aesthetic of timber), Trex decking saves upwards of 180 million tons of plastic and wood from landfill.

If environmental stewardship is important, installing a trex composite deck lets you enjoy the great Australian outdoor life with family and friends and look after the only Earth we have. It’s a great win-win outcome.

How do I decide between timber decking and Trex decking?

Can’t decide between Trex or timber?

That’s not an unusual dilemma.

The advance of sustainable and stylish composite deck products means timber is no longer the default choice for homeowners who want to expand their outdoor space and elevate their living.

Many Sydney homeowners use composite decking, particularly Trex decking, to install and enjoy their decks without considering maintenance schedules or costs.

The boards are not only environmentally friendly but are termite-proof, rot-proof, maintenance-free, and resist fading for 25 years. Trex manufactures the Transcend Range in 7 colours to suit a wide variety of Sydney homes, from ultra-modern to traditional homes in many of our older suburbs.

Say Goodbye to Termites and Wood-Eating Insects

Termites can devastate homes, causing tens of thousands of dollars in damages before you ever realize you’ve got a problem. And it’s estimated that 1 in 5 Sydney homes will suffer from termite damage at some stage…

But none of that is your concern.

Why Use Trex composite decking?

Problems with timber decking

The innovative structure of  Trex decking boards makes them termite-proof and protected against wood-eating insects. That means bugs can’t burrow into your new deck board and lay eggs, so the $100 million in damages caused by termites in Australia isn’t a bill you need to foot.

And with an early sign of termite damage often from splintering or damaged boards, your Trex composite deck is guaranteed to be termite-free and structurally sound for years.

Trex offers the most innovative and advanced composite deck product in the Australian market – and UrbanArch Building are leading installers of quality Trex materials.

4. Is Trex Deck Worth It?

How old is Trex decking?

The Trex Corporation was the first Company to create composite decking, combining the durable, sustainable material of recycled plastic and hardwood with the beautiful look of timber in 1996.

Trex has been offering market-leading composite deck products since 1996, growing to become the world’s leader in decking timber-alternative products. There were many imitators of Trex decking,  and then in 2010, Trex came up with their “game-changer”: the development of  Trex Transcend decking. This was the first product that could be used to build a deck resistant to fading, scratching, and stains. The Company (and its clients) haven’t looked back since then.

Where are Trex decking materials made?

The Trex Corporation was formed in America in  1996 through the buyout of a division of Mobil Corporation. 

With the largest market share of composite decking in North America, a growing international footprint, and over one billion in sales, the Trex corporation leads the industry globally. Today, the company offers the industry’s most comprehensive high-performance composite products. These products are available in more than 40 countries around the world.

All Trex composite decking products are made in the USA.

Does Trex decking need painting or staining?

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.

Is a Trex deck worth it?

If you want to save money, time and hassle,  a Trex deck costs more than a timber deck initially. But you’ll save money in the long run as no regular maintenance (sanding, acid washing and oiling) is required. There are virtually no maintenance costs once your Trex deck has been installed.

There’s just the occasional wash down with a hose and broom to contend with – and plenty of time to sit and relax on your deck and enjoy a glass of wine.

Is a Trex decking suitable for the Australian climate?

Yes. Trex composite decking is a highly durable material that can withstand severe weather conditions in Australia without rotting, staining, warping, or breaking down.

It doesn’t matter what our weather throws at it: heat, storms, winds and hail,   Trex Transcend maintains its vibrant finish. Trex has now become the most trusted, reliable brand of outdoor composite decking—not just in the United States but worldwide.

It’s ideally suited to our Sydney conditions, whether you want to use it as a stand-alone deck at home, combine it with an awning or pergola for the ultimate in-home comfort, or on the top floor of an apartment building.

Trex decking materials are your go-to product.

Is Trex decking a good choice for around a pool in Sydney?

If you have just installed a new pool or are looking to refresh or update a tired pool surround, Trex decking materials are an excellent choice. Not only is a Trex deck suited to our harsh Australian climate, but it will 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.

For the best results, make sure that you pair Trex decking boards with a suitable substructure, such as H4 low deck timber, for your joists and bearers. This will give your deck a trouble-free lifespan of 25 years or more.

Do Trex composite deck materials get hot?

All composite and natural timber materials will absorb heat and get hot on scorching days, and Trex decking materials are no exception. Composite materials 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.

How is a Trex deck 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.

These fasteners helped revolutionize the installation of deck boards and saved many hours on the traditional timber deck board installation.

Trex has engineered its boards to be as simple to install as they are to care for. Smaller decks can be completed in three or four days, while larger, more complicated projects can take up to a month. You will be amazed at the transformation of your outdoor space.

Will Trex decking warp?

No. The Trex Transcend range was a game changer when it was first introduced to the Australian market in 2010. It was the first composite decking range that finally delivered what clients sought and offered unprecedented advantages over other composite deck boards. The boards didn’t suffer from common problems at the time, like splitting and fading, and they never warp when correctly installed. It has remained the industry’s leading composite decking product ever since.

That, along with a 25-year straightforward warranty, is why Trex is the worldwide market leader in composite decking products.

What are the disadvantages of Trex 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 Trex range – Trex Lineage has been engineered to be significantly more relaxed 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 composite 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.

All exterior building materials require cleaning. Generally, soap and water is all that is required to clean Transcend, Enhance and Select products. For further information, see below.
Dirt and DebrisThe affected area should be sprayed off with a hose to remove surface debris. Use warm soapy water and a soft bristle brush to remove dirt and debris from the embossing pattern.
Chalk LinesHigh performance chalk lines may discolor the surface. Use only Irwin Strait-Line®* Dust-Off Marking Chalk (purple), available at
Tannins Due to DebrisRemove all debris using a hose or broom. Once the surface is dry, apply a Deck Brightener** as directed by the manufacturer. Deck Brighteners contain oxalic acid, which will also remove tannins.
Ice and SnowA plastic shovel may be used to remove snow from the board. Use calcium chloride or rock salt to melt the snow and ice from the surface.
Oil, Grease and FoodAll food spills should be removed as soon as possible. The surface must be cleaned within seven days to maintain the stain warranty. To remove, spray off with a hose and use warm, soapy water and a soft bristle brush to remove spills from the embossing pattern.
Mold and MildewIf debris such as pollen and dirt is allowed to remain on the surface, mold can feed on the biofilm. Using a hose and warm, soapy water with a soft bristle brush is recommended to remove the food source
and mold.
Using a Pressure Washer (Concrete,
Stucco or Ground-in Construction Dirt)
A pressure washer with no greater than 3100 psi***** that has a fan attachment/adjustment and soap dispenser may be used to remove dirt, concrete dust, or other types of construction dirt. Spray the board with soap, then follow with gently scrubbing each board with a soft bristle brush. Spray/rinse each individual board using a fan tip no closer than 8″ from the surface. RINSE THOROUGHLY as if dirty water from cleaning is left to dry, this will cause a film to remain on the surface.
Maintaining Transcend and Select RailingNEVER use acetone or other solvents on Trex Transcend or Select railing to maintain the beauty of the surface. For color transfer issues (from attachment of baluster spacer), use Mr. Clean® Magic Eraser® Original or Magic Eraser® Extra Power to help remove this.*** For small surface scratches, marks, or scuffs, use Dupli-Color Scratch Seal™ Clear Sealer Pen. ****

*Strait-Line® is a registered trademark of Irwin Industrial Tool Company.
**Use of products containing bleach or acid will lighten the surface of Trex. Use in an inconspicuous area to determine whether you like the effect. Neither product will affect the structural integrity of Trex.

****Scratch Seal™ Clear Sealer Pen is a registered trademark of Dupli-Color® Products Company.
