Colorbond vs Timber Fencing Quick Answer Australia
Colorbond typically costs more upfront but is steel: it doesn't rot, feed termites or need repainting, so ongoing maintenance is minimal. Timber usually costs less upfront but needs re-staining or repainting every few years and more repairs over its life, which narrows or reverses the gap over time. Pick Colorbond for low maintenance and durability; pick timber for a natural aesthetic and lower upfront cost. Check current per-metre pricing with local fencing contractors - height, gates and site access move quotes.

Colorbond vs Timber Fence: Cost, Lifespan, Maintenance Comparison Australia
| Factor | Colorbond | Timber (Treated Pine) | Timber (Hardwood) |
|---|---|---|---|
| Upfront Cost | Typically higher - get quotes | Typically lowest - get quotes | Between the two - get quotes |
| Lifespan | Longest - steel doesn't rot | Shortest - treatment and drainage dependent | Longer than pine - species dependent |
| Maintenance | Minimal - annual hose | High - stain every 2-3 years | Medium - oil every 3-5 years |
| Bushfire Rating | BAL rated - check current product documentation | Combustible | Requires treatment |
| Termite Resistance | Not susceptible (steel) | Requires treatment | Naturally resistant |
| Coastal Suitability | Excellent (corrosion-resistant) | Poor (rots faster) | Good with treatment |
| Sound Dampening | Moderate (reflects sound) | Good (absorbs sound) | Excellent (dense timber) |
| Color Options | 20+ colors | Unlimited (paint/stain) | Natural + stain options |
| DIY Installation | Difficult | Moderate | Moderate-Hard |
| Warranty | Check BlueScope's current warranty terms for your area | Varies by supplier - check terms | Varies by supplier - check terms |
| Recyclability | Recyclable (steel) | Biodegradable | Biodegradable |
Long-Term Cost of Ownership: What to Compare
Timber usually looks cheaper on the initial quote, but the materials age differently and the recurring costs land in different places. Compare quotes across the life you expect from the fence, not just the install price:
Colorbond (1.8m height)
- One-off install: a single professional install is where nearly all the cost sits - get itemised quotes
- Ongoing: occasional hosing down and a fastener check - no repainting cycle
- Repairs: individual panels can be replaced if damaged
- Ask in quotes: post depth and footing spec, capping, gate hardware, old-fence removal
Treated Pine Timber (1.8m)
- Lower install cost: typically the most affordable material upfront - get itemised quotes
- Recurring: re-staining or repainting every 2-3 years - price a re-coat for your fence length before committing
- Repairs: budget for paling replacement and re-fixing warped boards over the fence's life
- Ask in quotes: treatment class of the timber, post material (steel posts outlast timber posts), drainage at the base
The comparison that matters: install cost plus every re-coat and repair cycle over the fence's life - itemised quotes for both materials make that visible.
Also weigh the time cost: timber's maintenance is recurring hands-on work, while Colorbond's is close to none.
When to Choose Colorbond vs Timber: Decision Guide Australia
✓ Choose Colorbond If You:
- • Live in a coastal area or high-salt environment
- • Are in a bushfire-prone zone (BAL-12.5 or higher)
- • Want low maintenance and are time-poor
- • Have a modern or contemporary home design
- • Value long-term cost savings over upfront price
- • Want maximum privacy with solid panels
- • Need termite-proof fencing
- • Plan to stay in your home long-term (10+ years)
✓ Choose Timber If You:
- • Have a character, cottage, or heritage home
- • Prefer a natural, warm aesthetic
- • Have a tight upfront budget (though costs more long-term)
- • Live in an area where timber is the neighborhood standard
- • Want better sound dampening (near busy roads)
- • Enjoy DIY projects and have carpentry skills
- • Don't mind regular maintenance (staining every 2-3 years)
- • Want to change colors easily with paint/stain
Colorbond vs Timber Installation: DIY, Time, Professional Costs Australia
Colorbond Installation Process
Professional installation typically takes 1-2 days for a 30m fence:
- Posts: Steel posts set in concrete (900mm deep), spaced 2.4m apart
- Rails: Top and bottom rails fixed to posts with tech screws
- Panels: Colorbond sheets riveted to rails with pop rivets
- Finishing: Capping installed on top of panels for clean finish
Tools required: Post hole digger, spirit level, pop rivet gun, drill, metal snips, measuring tape
Timber Installation Process
DIY or professional installation takes 2-3 days for a 30m fence:
- Posts: Timber or steel posts in concrete (600-900mm deep), spaced 2.4-2.7m
- Rails: 2-3 horizontal timber rails nailed or screwed to posts
- Palings: Vertical timber palings nailed to rails with consistent spacing
- Finishing: Optional capping and sealing/staining applied
Tools required: Post hole digger, spirit level, saw, drill, nail gun, measuring tape, paintbrush
Common Fencing Mistakes to Avoid in Australia
Don't:
- • Choose based solely on upfront cost without considering lifetime expenses
- • Install timber fencing in direct contact with soil (causes rot)
- • Use untreated pine posts below ground (they rot quickly in soil)
- • Paint/stain wet timber (must be dry for proper adhesion)
- • Install Colorbond without checking color against your roof
- • Attempt DIY Colorbond if you lack metal fabrication experience
- • Skip neighbor consultation (avoid costly disputes later)
✓ Do:
- • Get multiple quotes (3-5) to compare pricing and services
- • Check installer credentials and ask to see previous work
- • Use steel posts for timber fences (they outlast timber posts)
- • Apply wood treatment/stain to timber immediately after installation
- • Consider bushfire rating requirements for your area (BAL zones)
- • Choose lighter Colorbond colors in hot climates (less heat retention)
- • Get council approval before installation if required by local laws
Sources & Further Reading
- • Shared boundary fences are governed by state dividing fences laws - see for example the WA Government's dividing fences guidance, and check the equivalent guidance for your state.
- • Consumer guarantees apply to fencing materials and workmanship in addition to any manufacturer warranty - see the ACCC.
- • Product-specific claims (warranty periods, BAL ratings) change over time - rely on BlueScope's current published documentation rather than third-party summaries, including this one.
