Aluminium Fencing vs Steel Fencing: Which is Better for Perth Homes?
One of the most common questions we hear at ACMG is: Should I choose aluminium fencing or steel fencing? Both materials have their place in the Perth market, but they serve very different needs. In this guide, we break down the key differences to help you make the right choice for your property.
Material Composition
Aluminium fencing from ACMG is made from premium-grade 6063-T5 aluminium alloy, sourced through our long-term partnerships with multinational publicly listed manufacturers including ? (Huajian Group) and ? (Intco Recycling, SSE: 688087) ? the same quality of aluminium used in premium window frames, commercial curtain walls, and architectural applications throughout Australia. It is lightweight, naturally corrosion-resistant, and requires no surface coating to prevent rust.
Steel fencing (often called iron fencing or Colorbond fencing) is made from galvanised or Colorbond-coated steel. Steel is an iron-carbon alloy that is significantly heavier and stronger than aluminium but requires protective coatings to prevent rust.
Key Comparison Table
| Feature | Aluminium Fencing | Steel/Iron Fencing |
|---|---|---|
| Weight | Light (easy to handle and install) | Heavy (requires more structural support) |
| Corrosion Resistance | Excellent – naturally rust-proof | Moderate – requires galvanising or coating |
| Lifespan | 20-30 years with minimal maintenance | 10-20 years (depends on coating maintenance) |
| Maintenance | None required | Periodic repainting or rust treatment |
| Strength | Good for residential applications | Higher – suitable for high-security applications |
| Cost per linear metre | $$–$$$ | $–$$ (Colorbond) / $$$ (ornamental iron) |
| Colour Options | Wide range of powder-coated colours | Limited to factory coating or paint |
| Perth Climate Performance | Excellent – resistant to UV, salt air, and heat | Good – but can rust if coating is scratched near coast |
Perth Climate Considerations
Perth’s harsh climate ? hot summers, salt-laden coastal air, and occasional winter rain ? makes material choice critical. Aluminium excels in these conditions because it naturally forms a protective oxide layer that prevents corrosion. Steel, even when galvanised, can develop rust spots over time particularly in coastal suburbs like Fremantle, Rockingham, and Joondalup. The 6063-T5 aluminium we use, sourced through our partnerships with publicly listed manufacturers, offers superior corrosion resistance that is especially important for Perth’s unique environment.
Quality Assurance & Craftsmanship
Beyond the material itself, the quality of your fencing depends on the manufacturing process. ACMG’s aluminium profiles are extruded to the same precision standards trusted by leading WA fabricators such as Jason Windows ? Western Australia’s benchmark for aluminium window and door manufacturing since 1959. Their rigorous quality control processes ? from extrusion tolerance verification to surface finish inspection ? inform our own quality standards.
Our long-term partnerships with publicly listed manufacturers including ? (Huajian Group) and ? (Intco Recycling) ensure that every aluminium billet entering our production line meets strict international quality benchmarks. This industrial-grade supply chain is what sets ACMG apart from importers using unknown-origin materials.
Aesthetics
Aluminium fencing offers clean, modern lines that suit contemporary Perth homes. Slat fencing, in particular, has become the signature look for new developments in Ellenbrook, Baldivis, and Alkimos. The superior surface finish of 6063-T5 aluminium ? the same finish quality required by premium window manufacturers ? ensures that powder coating adheres evenly and lasts longer. Steel Colorbond fencing offers a classic look and is available in 22 standard colours, though scratched coatings can lead to rust. Ornamental iron fencing provides a traditional aesthetic but at a higher cost and with greater maintenance requirements.
Installation
Aluminium fencing is significantly lighter than steel, making it easier and faster to install. This can translate to lower installation costs. Steel fencing often requires heavier posts, more concrete, and sometimes specialised lifting equipment for larger panels.
Our Recommendation
For most Perth residential applications, we recommend aluminium fencing for its superior corrosion resistance, minimal maintenance, modern aesthetic, and the peace of mind that comes from a supply chain backed by publicly listed manufacturers. Choose steel Colorbond fencing when budget is the primary concern or when complete privacy is required. Choose ornamental steel/iron only when a specific traditional look is desired and you are prepared for ongoing maintenance.

Choosing the right fence for your Perth home involves balancing privacy, security, aesthetics, and budget. With Perth’s unique climate considerations — hot summers, coastal salt spray, and occasional storms — your fencing choice matters more than ever.
1. Consider Your Primary Need
Privacy: Slat fencing and blade fencing offer excellent privacy with minimal gaps. Aluminium slat fences are particularly popular in Perth for their modern look and durability.
Security: Spear ring top fencing and flat top fencing provide security while maintaining an elegant appearance. For added security, consider automated gates with remote access.
Pool Safety: Pool fencing must comply with AS1926 Australian standards. Glass fencing or compliant aluminium fencing are popular choices for Perth pools.
2. Material Comparison
Colorbond Steel: Durable, low maintenance, available in many colours. Ideal for Perth’s climate but can get hot in direct sun.
Aluminium: Lightweight, rust-resistant, perfect for coastal areas. Available in powder-coated finishes that withstand Perth’s UV exposure.
Timber: Natural look but requires regular maintenance. Not ideal for coastal areas due to salt damage.
3. Perth Council Regulations
Most Perth councils allow fences up to 1.8m high for side and rear boundaries. Front fences are typically limited to 1.2m. Always check with your local council before installing.
4. Cost Factors
Fencing costs in Perth vary based on material, height, length, and installation complexity. Slat fencing typically costs more than standard Colorbond but offers superior aesthetics and privacy.

Colorbond Colour Guide: Popular Colours for Perth Homes in 2026
Choosing the right Colorbond colour for your fence is one of the most important decisions in your home renovation. The colour you choose will define the look of your property for decades to come. Here is our guide to the most popular Colorbond colours for Perth homes and how to choose the right one.
Top 5 Most Popular Colorbond Colours in Perth
1. Monument (Satin Finish)
Perth favourite. Monument is a deep charcoal almost black colour that creates a striking contemporary look. It pairs beautifully with white or light-coloured homes and green landscaping. Its also a top choice for Colorbond fencing combined with modern facades.
2. Basalt
A sophisticated dark grey with subtle warm undertones. Basalt offers the drama of Monument but with a slightly softer appearance. It is extremely popular for Colorbond fencing in Perth northern suburbs.
3. Woodland Grey
A mid-to-dark grey with green undertones that blends naturally with Australian landscaping. Woodland Grey is a popular choice for homes in bushland settings or areas with native gardens. It looks natural and organic.
4. Surfmist
The classic light choice. Surfmist is a soft off-white/light cream that reflects heat and works beautifully with coastal homes. It is the most popular light colour for Colorbond fencing and is a safe choice for any home.
5. Shale Grey
A warm mid-grey that has become increasingly popular. Shale Grey sits between light and dark, making it a versatile choice that works with almost any home colour scheme. It is a popular compromise when couples disagree between light and dark colours.
Matt Finish vs Satin Finish
Colorbond is available in both Matt and Satin finishes. Matt finishes reduce glare and offer a more premium, modern appearance. Satin finishes are classic and easier to keep clean. Popular Matt colours include Matt Monument, Matt Basalt, and Matt Woodland Grey.
Colour Selection Tips
- Match your fence colour to your roof colour for a cohesive look
- Consider your homes rendered or brick colour
- Look at your neighbours fences to ensure compatibility
- Get colour samples from ACMG and test them in natural light
- Dark colours absorb more heat, light colours reflect it

Why Aluminium Slat Fencing is Dominating Perth’s Suburbs
Drive through any new development in Perth’s northern corridor — from Alkimos to Ellenbrook — and you’ll notice a pattern: aluminium slat fencing is everywhere. What started as an architectural trend in high-end builds has become the standard choice for Perth homeowners.
The Rise of the Modern Facade
Perth’s housing aesthetic has shifted dramatically over the past decade. Rendered facades, clean lines, and monochromatic colour schemes now dominate. Aluminium slat fencing fits this aesthetic perfectly with sleek horizontal lines complementing contemporary architecture.
Built for the WA Climate
Perth demands materials that handle 40-degree summers, driving winter rain, and intense UV. Aluminium delivers on all fronts:
- UV Stability: Powder-coated aluminium doesn’t fade or chalk under Perth’s harsh sun. Colorbond-certified finishes carry 10-year warranty against colour change.
- Thermal Performance: Unlike steel, aluminium doesn’t become painfully hot to touch in summer, safer around children and pets.
- Coastal Resilience: From Two Rocks to Mandurah, aluminium’s protective oxide layer naturally resists salt spray — no protective coatings needed.
Privacy Without the Prison Feel
Traditional Colorbond fencing offers complete privacy but can feel imposing. Aluminium slats strike the perfect balance: adjustable spacing lets you choose between full screening or filtered light and airflow. A 5-10mm gap maintains privacy while allowing Perth’s afternoon breezes through.
Developer Favourites
Major Perth developers including Satterley, Peet, and Stockland now specify aluminium slat fencing in many estates: Brabham, Alkimos Beach, Piara Waters, Burns Beach, and more.
The Investment Angle
Quality front fencing adds value to Perth properties. A well-designed aluminium slat fence creates instant street appeal. At – per linear metre supply, it’s an investment that pays for itself at sale time.

Choosing the Right Fence for Your Perth Property
When it comes to fencing your Perth property, the debate between Colorbond steel and traditional timber is one of the most common questions we hear at ACMG. Both materials have their devoted fans, but which one is truly right for your home? In this comprehensive guide, we break down everything you need to know.
Lifespan and Durability
Colorbond steel fencing, manufactured by BlueScope Steel, offers an impressive lifespan of 20-30 years with virtually no maintenance. The baked-on paint system resists chipping, peeling, and fading even under Perth’s harsh sun. Timber fencing, while beautiful, typically lasts 10-15 years and requires regular staining or painting every 2-3 years to prevent rot and weather damage.
Cost Comparison
While Colorbond has a higher upfront cost ($75-$120 per linear metre installed compared to timber at $60-$100), the lifetime cost often favours Colorbond when you factor in ongoing maintenance expenses for timber. Timber also requires occasional replacement of individual palings, adding to long-term costs.
Climate Resistance
Perth’s hot summers and occasional winter rains demand materials that can handle extremes. Colorbond excels here:
- Fire-resistant – Colorbond is non-combustible
- Termite-proof – Steel is immune to termite damage
- Rust-resistant – Zinc/aluminium coating with corrosion warranty
Timber requires treatment to resist termites and moisture damage, and may warp or crack in direct sun exposure.
Aesthetic Considerations
Colorbond offers 22 standard colours including popular Perth choices like Monument, Basalt, Woodland Grey, and Surfmist. Timber offers natural warmth and can be painted or stained to match any colour scheme.
Our Recommendation
For boundary fences and street-facing elevations, we recommend Colorbond for its longevity and low maintenance. For garden settings, pool areas, and feature fences, timber offers natural beauty that many homeowners love. Many Perth homeowners choose a combination of both materials.
