Ironbark Timber Post and Rail Fencing: The Dense and Finest Hardwood 

Ironbark - hardwood post and rail fence

Preferred by premium property owners, Ironbark is amongst the best hardwood options you can get in our country. 

It stands out as a sturdy and robust option for fence posts, showcasing exceptional strength and durability. With its natural resistance to decay and termites, Ironbark proves to be a reliable and beautiful choice for long-term fencing solutions. 

However, its dense nature might pose challenges during morticing. The ‘denseness’ can be very tough on your gear, heavy to lift, and slower to cut/handle.  Checking with your supplier for customisation is highly recommended. 

Ironbark’s availability and pricing may vary, depending on the sourcing location and market demands.

Its remarkable Class 1 durability in-ground and above-ground ratings make it an ideal option for long-lasting fence construction.  

Forest Red Gum offers exceptional qualities, however, its availability and pricing may vary depending on market demand and regional sourcing. Proper maintenance and protective measures can ensure its longevity and preserve its captivating appearance over time.

Spotted Gum emerges as a popular choice for rail fencing, renowned for its attractive light to dark brown hues and exceptional resilience. Its long strands provide flexibility within the rails, reducing the likelihood of breakage or bending, and ensuring a sturdy and reliable fence structure. 

Given the fact Spotted Gum is best suited to rails, it is not uncommon to use Spotted Gum Rails with Ironbark posts as they both have a similar colour. 

While Spotted Gum remains readily available, it is essential to consider sourcing from reputable suppliers to maintain consistent quality. Additionally, a proper protective coating can prolong its lifespan and preserve its natural aesthetics. 


Spotted Gum 

Durability Class in Ground: Class 1 (15-25 years +) 

Rating Above Ground: Class 1 (40 years +) 

Termite Resistant: Yes 

Colour: Light Brown to Dark Red 


White Cypress: The Reliable and Cost-Effective Choice

With its impressive termite resistance and Class 1 durability above ground, White Cypress presents itself as a cost-effective and reliable timber option for fencing projects. While it may not possess the same density as some hardwood counterparts, White Cypress offers a viable solution for customers with budget constraints. 

However, its Class 2 durability on the ground and pricing dependent on availability call for prudent consideration. 

Tip: Source White Cypress from Southern Queensland which is a high-quality hardwood, be cautious of buying Victorian Cypress or Macocarpa, known for issues such as splitting or warping.
