Is Trex 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. A composite board is quicker to install and doesn’t have hardwood’s annual maintenance costs. Think sanding, acid washing, and oiling. Maintenance costs with a reputable firm will usually be $40 – $80 an sq metre per year. That adds up to high maintenance costs over the life of your deck.
When you consider that the average Sydney deck is between 30 square metres 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 $50 a sq metre x 10 years = $17,500.
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 inside it’s a different story. 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 great 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. By using unwanted timber from woodworking projects and recyclable materials, Trex Composite decking offers a range of sustainable decking options for your home.

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 timber from landfill.
If environmental stewardship is important to you, 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 and Trex?
Can’t decide between Trex or timber?
We get it.
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 are deciding to use composite decking, particularly Trex decking, so they can 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 will 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 found 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?
- NO rotting boards
- NO termite damage
- NO more cracked or splitting boards
- NO splinters
- NO sanding - ever
- NO oiling - ever
- NO more to spend on maintenance


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 coming in the form of splintering or damaged boards, your Trex composite deck is guaranteed to be termite-free and structurally sound for years to come.
Trex offers the most innovative and advanced composite deck product in the Australian market – and UrbanArch Building are leading suppliers and installers of quality Trex materials.

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.
What Trex deck colours are available?
The Trex transcend colour range is available in Australia. It debuted in 2010 and is available in 7 colours to complement any home, business, or outdoor space. It has become the most popular range of decking products in Australia.
There are 5 premium Tropical colours and 2 classic Earth tones available.
Tropical colours: Island mist, Havana gold, Lava rock, Spiced rum and Tiki torch
Earth colours: Rope swing and Gravel path
Trex Transcend maintains the vibrancy of its colours and its luxurious embossed finish for a warranted 25-year period – with very little if any, maintenance.
If you would like to see a larger Trex sample in your home, call us on 0413 185 735 today, and we will be happy to organize that for you.



Trex Island mist: A cool combination of relaxing silver tones, it has the weathered look of driftwood. Perfect for coastal properties or the modern, stylish home popular in Sydney today.



Trex Havana gold: An aspiring blend of caramel and honey hues, it is a warm brown color that looks like tropical teak and is perfectly suited to most Australian modern brick homes.



Trex Lava rock: Featuring rich reddish-black undertones, Lava Rock looks and feels like a magnificent redwood with a rich, warm palette of colours.



Trex Spiced rum: A deep brown with onyx black lowlights, Spiced Rum resembles the rich deep brown of Brazilian walnut timber.



Trex Tiki Torch: Featuring hints of nutmeg and ginger, Tiki Torch is a cool light brown designed to imitate tropical teak.



Trex Rope swing: An understated, sandy mushroom colour, it’s a cheerful color for an outdoor place to relax.



Trex Gravel path: Like a rocky country lane, Gravel Path brings a pristine grey to any outdoor setting.
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 array of high-performance composite products. These products are available in more than 40 countries around the world.
All Trex decking products are made in the USA.
How often does Trex 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 test of aesthetic style, with a range of beautifully crafted products.
Is a Trex deck cost-effective?
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 deck suitable for the Australian climate?
Yes. Trex decking is a highly durable material that can withstand the severe weather conditions found 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 a Trex deck a good choice for around a pool?
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 on a really hot day, you really won’t be able to tell the difference.
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 as heating up won’t be an issue.
How long does a Trex deck take to install?
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 its transformation to your outdoor space.
Will Trex decking warp?
Definitely not. The Trex Transcend range of decking boards was a game changer when they were first introduced to the Australian market. They were the first composite decking material that finally delivered what clients sought. They didn’t suffer from common problems at the time, like splitting and fading, and they never warp when correctly installed. That was the case then, and it is still the case now – and that, along with a 25-year straightforward warranty, is one of the reasons that helped make Trex the worldwide market leader it is today.

PROBLEM | SOLUTION |
---|---|
Dirt and Debris | The 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 Lines | High performance chalk lines may discolor the surface. Use only Irwin Strait-Line®* Dust-Off Marking Chalk (purple), available at Irwin.com |
Tannins Due to Debris | Remove 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 Snow | A 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 Food | All 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 Mildew | If 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 Railing | NEVER 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. **** |
