WPC Fencing vs Colorbond Fencing for Pool Safety: Which Is Better for Long-Term Compliance?
Choosing a fence near a swimming pool is about more than appearance and privacy. Australian pool safety regulations require pool barriers to meet strict safety standards, and small design details can sometimes make a significant difference during a pool safety inspection.
At Comfyard, we regularly install and replace fences around swimming pools across Brisbane, the Gold Coast and Sydney. One issue we encounter surprisingly often involves existing Colorbond fencing that has been identified by pool certifiers as requiring modification before a property can receive pool compliance certification.
Understanding Pool Barrier Height Requirements
Australian pool safety regulations generally require pool barriers to maintain a minimum effective height while avoiding climbable elements that could assist a child in scaling the fence.
Although the exact requirements depend on the applicable Australian Standard, state legislation and the assessment of the certifying inspector, the concept of non-climbable zones is fundamental to pool barrier compliance.
This is where the design differences between Colorbond fencing and WPC fencing become particularly important.
Why Some Colorbond Fences Become a Compliance Issue
A standard 1800 mm Colorbond fence is constructed using steel sheets fixed between a bottom rail and a top rail.
In practice, many pool certifiers assess the top edge of the bottom rail as a potential climbable point because it projects horizontally from the fence surface.
As a result, the effective measurement may be taken from the upper edge of that bottom rail rather than from ground level.
In some situations, this means the effective barrier height is considered to be approximately 1750 mm instead of the nominal 1800 mm.
Leaving aside the debate about whether this interpretation is always reasonable, the reality is that homeowners may still be required to address the issue before obtaining pool certification.
The Cost of Upgrading an Existing Colorbond Fence
When a Colorbond fence is determined not to satisfy the required pool barrier configuration, the available solutions can be expensive.
In many cases, homeowners need to:
· Replace the existing sheets with taller panels
· Install longer fence posts
· Rebuild significant sections of fencing
· Repaint or match existing fence colours
· Re-landscape affected areas
Depending on the property, the required work can become a substantial and unexpected expense.
Why WPC Fencing Offers a Practical Advantage
The design of WPC fencing is fundamentally different.
Unlike traditional Colorbond fencing, a WPC privacy fence presents a continuous flat surface without exposed horizontal rails on the climbing side of the fence.
Because the fence face remains in a single vertical plane, there are no equivalent horizontal ledges created by bottom rails that commonly attract attention during pool inspections.
This simplified design makes WPC fencing an excellent choice for homeowners planning a new pool area or replacing an ageing boundary fence.
It is important to note that every pool barrier must still be assessed as a complete system and certified according to the applicable regulations. However, the structural design of WPC fencing removes one of the common concerns encountered with some conventional fence designs.
The table below compares WPC fencing and Colorbond fencing across the factors that matter most for pool owners, including safety, maintenance, durability and long-term value.
| Feature | WPC Fencing | Colorbond Fencing |
|---|---|---|
| Pool Safety Design | ✔ Smooth, continuous surface with no exposed horizontal rails on the climbing side. | ⚠ Bottom rail may be considered a climbable element during some pool inspections. |
| Pool Compliance | ✔ Flat-profile design removes one common concern, although every fence still requires certification. | ⚠ Some installations may require modifications before certification. |
| Future Height Extensions | ✔ Modular boards can often be extended if regulations change. | ✖ Height upgrades often require replacing sheets, posts and structural components. |
| Maintenance | ✔ No painting required. Simply wash occasionally. | ◐ Protective coatings may require repairs or repainting if damaged. |
| Moisture Resistance | ✔ Resistant to moisture, rot and termites. | ◐ Durable steel, but damaged coatings may increase corrosion risk. |
| Appearance | ✔ Modern architectural style with a premium timber look. | ◐ Traditional steel appearance. |
| Durability Around Pools | ✔ Excellent performance in wet and humid environments. | ◐ Durable but generally requires more long-term maintenance. |
| Long-Term Ownership Cost | ✔ Lower maintenance and easier future upgrades may reduce lifetime costs. | ◐ Future modifications and maintenance may increase ownership costs. |
| Privacy | ✔ Seamless solid panels provide excellent privacy. | ✔ Excellent privacy with visible rails and posts. |
| Best For | Homeowners seeking a modern, low-maintenance, future-ready fencing solution. | Homeowners who prefer a traditional steel fence. |
Note: Pool barrier compliance depends on the complete fence design, site conditions and the applicable Australian Standards and state regulations. Every swimming pool barrier should be assessed and certified by an accredited pool certifier.
Future Regulations May Change
Pool safety legislation continues to evolve.
As standards are updated and interpretations change, no manufacturer can guarantee that today's fence design will always satisfy every future regulatory requirement without modification.
One significant advantage of WPC fencing is its modular construction.
If future regulations require additional fence height, WPC fencing can often be extended by installing additional boards or compatible extension components without demolishing the entire fence.
By comparison, upgrading an existing Colorbond fence frequently requires replacing posts, sheets and structural components, resulting in considerably higher labour and material costs.
This flexibility provides homeowners with valuable long-term protection against changing compliance requirements.
Better Performance Around Swimming Pools
Swimming pool environments expose fencing to constant moisture, irrigation systems, pool chemicals and humid conditions.
Over time, these conditions can accelerate wear on conventional steel fencing, particularly where protective coatings have been damaged.
Quality WPC fencing is highly resistant to moisture, will not rot, and requires very little ongoing maintenance.
It never needs painting and is not affected by termites, making it an excellent long-term solution for pool surrounds.
WPC Fencing: A Smart Investment for Pool Areas
When comparing WPC fencing vs Colorbond fencing, cost is only one part of the decision.
Long-term maintenance, adaptability, appearance and potential future compliance costs should all be considered before selecting a fencing system.
For homeowners building a new pool or planning a pool fence replacement, WPC fencing offers several practical advantages:
· Low maintenance with no painting required
· Modern architectural appearance
· No exposed horizontal rails on the fence face
· Excellent durability in pool environments
· Easy future height extensions if regulations change
· Long service life with minimal upkeep
At Comfyard, we help homeowners choose fencing solutions that not only look great today but also remain practical, durable and adaptable for many years to come.
