Why Choose Ironbark Decking?

When it comes to ironbark timber, the name really says it all. Ironbark is tough as iron and a strong and durable timber option for Sydney decks no matter what suburb you call home. Ironbark has been used for years throughout Australia to build decks, structural beams, fencing, and even flooring, so you’re in safe hands – and on safe ground – when you opt for the durability of ironbark.

Having supported Sydneysiders with their decking dreams for the past 14 years, we’ve seen ironbark grow in popularity and it’s not hard to see why. Besides its strength, ironbark also comes in a range of attractive and unique colours, ranging from deep reds to pale yellows that look stunning in early morning sun right through to sunset. What’s more, this hardwood timber is highly resistant to rot, termites, and fire. This makes it an ideal choice for residents who live in bushfire-prone suburbs of Sydney. 

The short version? If you want to choose timber that’s built to last, then, we highly recommend ironbark.

Benefits of Ironbark Decking

Thanks to its high durability and popularity, Ironbark is one of the more expensive timber options, with prices generally falling between $110 to $200 per square meter.

How Long Will It Take to Install a New Ironbark Deck?

When it comes to your deck installation timeline, there are various factors to consider. Overall, the installation process will fall into three steps: 

STEP ONE: Planning, Design and Layout

STEP TWO: Foundation, Posts and Framing

STEP THREE: Decking, Railing and Stairs

Step one will always take you the longest. Filling out council applications and getting approval from your local Sydney council can take a long time! As can coming up with the perfect design and timber choice for your dream deck. That said, once this step is complete, the rest of the process will be quick, straightforward, and headache-free. 

And remember — at Urban Arch Building, we work hard to make sure that each job is completed to the highest possible standards, and with minimal disruption to your day-to-day life. Let us bring your backyard decking vision to life. Request a fast and free quote today.

Frequently Asked Questions About Ironbark Decking In Sydney

What colour is ironbark timber? 

There are two species of ironbark: red ironbark and grey ironbark: 

Red ironbark: Red ironbark heartwood is a deep dark red to red-brown. By contrast, its sapwood is a distinctive pale yellow in colour. 

Grey ironbark: Grey ironbark’s appearance ranges from reddish to dark brown heartwood. The sapwood is generally a little bit lighter in colour. 

How strong is ironbark? 

As the densest and heaviest Australian hardwood, ironbark is extremely strong, long-lasting, and durable. In fact, it has a durability rating of one, which is the highest possible score. That said, this immense strength can make ironbark difficult to install and work with, which is why you should always use an experienced expert to install an ironbark deck. 

What makes ironbark so durable?

So, what makes this timber so strong? Well, unlike other tree varieties, the ironbark eucalyptus doesn’t shed its bark annually. This makes it denser, stronger, and finer grained than other timber options. In fact, it’s the heaviest and densest Australian wood you’ll find on the market, and Ironbark decks are known to last 40 years or longer with minimal maintenance. 

What are common uses of ironbark? 

Because of its strength and density, ironbark is commonly used for: 

  • Decks
  • Handrails
  • Stairs
  • Built-in seating
  • Walkways
  • Building additions

Where does ironbark grow?

Ironbark is a native Australian species (so your new deck will be Australian-made to its core). Most ironbark trees grow in NSW, QLD and Victoria, although there are varieties unique to the Northern Territory and Western Australia.

Is ironbark an easy timber to work with?

No. Unlike blackbutt, which is easy to cut by hand or machinery, ironbark lives up to its name and can be difficult to work with. At Urban Arch Building we have the tools and the team to create striking ironbark decks, but the DIY route is not recommended.
