Why WPC Fencing Is Rare in Australia—and Where Lightweight ASA Composite Fencing Can Compete

Australia does not lack demand for composite fencing. The real challenge is that conventional wood plastic composite fencing is caught between several well established alternatives.

Colorbond fencing offers a mature supply network, standardised systems and relatively accessible project costs. Timber is familiar to builders and can be modified easily on site. PVC is lightweight and well suited to vertical installation. Conventional WPC, although valued for its timber like appearance and low maintenance positioning, is generally heavier and more expensive than mainstream fencing materials.

This means that lightweight ASA composite fencing should not be positioned as a universal replacement for Colorbond. Its more realistic opportunity lies in projects that need something the mainstream options do not provide:

· a warmer, more architectural appearance than standard metal fencing;

· lightweight boards suitable for vertical and double sided privacy systems;

· decorative cladding for existing Colorbond fences, prefabricated buildings and outdoor feature walls.

The opportunity is therefore not to defeat Colorbond in a price competition. It is to fill the design and performance gaps between Colorbond, PVC and conventional WPC.

Why Colorbond Is So Strong in the Australian Fencing Market

Any composite fencing strategy in Australia must begin by understanding why Colorbond is difficult to challenge.

According to BlueScope, fencing made from genuine COLORBOND® steel is available in 14 core colours, does not rot, is not vulnerable to termite damage, is suitable for use in bushfire prone areas and is backed by a 15 year warranty, subject to the relevant terms and eligibility conditions. The steel also conforms to AS 1397:2021 and AS/NZS 2728:2013.

These advantages are supported by an established ecosystem of manufacturers, distributors, installers and standard components. For many suburban boundary fence projects, buyers already know what Colorbond looks like, how it is installed and where replacement parts can be obtained.

Field observations collected during Australian market visits in 2023 similarly placed Colorbond ahead of timber, PVC, bamboo, wire and WPC fencing. These observations should be treated as channel feedback rather than official market share statistics, but they demonstrate how strongly metal fencing is embedded in local purchasing habits.

For composite manufacturers, the lesson is clear: competing directly on the lowest initial price is unlikely to be effective.

A stronger comparison should consider the complete project rather than a single headline about material lifespan. Buyers need to evaluate:

· material and installation costs;

· maintenance requirements;

· appearance and colour retention;

· privacy on both sides of the fence;

· suitability for coastal, high temperature and high wind environments;

· bushfire related documentation where relevant;

· the ability to replace damaged boards or accessories locally.

Even Colorbond warranties vary according to the application, location and eligibility criteria. Broad claims such as “50 year life” should therefore not be treated as a universal benchmark for comparing unrelated fencing systems.

Why WPC Fencing Remains a Premium Niche

WPC fencing is not unknown in Australia. The barrier is that awareness has not yet translated into widespread specification.

A longer market education cycle

Australian builders and distributors generally have more experience with composite decking than with composite fencing. A deck board is normally supported at frequent intervals by a subframe. A fence panel, by contrast, becomes part of a taller structure exposed to wind pressure, impact, thermal movement and ground level moisture.

Consequently, buyers need evidence not only about the board material, but also about:

· post spacing;

· rail design;

· connection details;

· footing requirements;

· thermal expansion;

· wind pressure performance;

· long term access to spare parts.

The 2023 channel research behind this article found that the principal obstacle was not a complete lack of WPC awareness. It was the shortage of familiar installation systems, established local cases and long term structural references for builders and distributors.

A price to application mismatch

Conventional WPC fencing is often positioned above Colorbond, timber and PVC. That makes it unsuitable for treating the entire residential boundary fence market as one target segment.

The more promising applications are those in which visual value, privacy or architectural differentiation can justify a premium, including:

· decorative front yard fencing;

· high end residential privacy fences;

· hotels, resorts and landscaped commercial developments;

· shared boundaries where both neighbours want an attractive finished surface;

· decorative cladding installed against an existing metal fence;

· prefabricated buildings and outdoor feature walls.

These are projects in which the cheapest barrier is not necessarily the buyer’s primary objective.

The Australian Design Signals: Vertical, Double Sided and Architectural

The Australian market has already provided several useful product development signals.

Channel observations in 2023 identified fence sections of approximately 1,800 mm high by 2,400 mm wide as a common reference point. Vertical boards were widely requested, bottom rails or plinth boards were commonly used, and customers showed interest in ribbed “Great Wall” profiles and double sided designs.

These preferences create a structural challenge for conventional WPC.

In a horizontal fence, boards can be supported along their length and may transfer part of their weight through an overlapping or stacked arrangement. In a vertical fence, the bottom rail, top rail, posts, fasteners and foundations must work together to support the boards and resist wind loads.

A double sided profile can increase both the system weight and the effective area exposed to wind. Simply rotating a conventional horizontal WPC board by 90 degrees is therefore not a complete vertical fence solution.

The entire system must be designed around vertical installation from the beginning.

How ASA Composite Fencing Can Fill the Gap Between WPC and PVC

ASA composite fencing can be relevant where projects need the lighter handling associated with PVC but want a deeper, more architectural surface than standard vinyl fencing usually provides.

1. Reducing the weight barrier for vertical installation

Indicative Mexytech product data places standard WPC density at approximately 1.2–1.4 g/cm³ and lightweight ASA co extrusion structures at approximately 0.7–0.85 g/cm³. The actual weight must always be confirmed for the selected profile, dimensions and formulation.

A lighter board can reduce handling demands and the dead load bending moment applied to rails and connections. It may also make vertical systems more practical for installers.

However, density alone does not determine whether a fence is structurally suitable.

Wind performance still depends on:

· board width and thickness;

· post material and wall thickness;

· post centres;

· top and bottom rail design;

· fasteners and connection points;

· footing dimensions;

· terrain and wind region;

· the height and permeability of the completed fence.

The responsible claim is therefore that lightweight ASA construction provides a better material foundation for vertical fencing—not that every ASA board is automatically suitable for every vertical installation.

2. Moving beyond the plastic appearance of basic PVC fencing

PVC has an important practical advantage: it is light and relatively easy to install vertically. Its limitation is often aesthetic. Some products have restricted colour depth, visible gloss or a uniform surface that does not suit premium architectural projects.

An ASA exterior layer can support matt finishes, embossed grain patterns and richer timber inspired colours. Depending on the final colour range, possible directions include teak, rosewood, antique timber and golden oak tones.

This creates a useful middle position:

· lighter than many conventional WPC boards;

· warmer in appearance than painted metal;

· more timber like than basic PVC;

· lower maintenance than natural timber.

Actual colour availability, weathering performance and batch consistency should always be confirmed with physical samples and product specific reports.

3. Creating a double sided fluted privacy fence

A double sided fluted—or “Great Wall” style—profile responds to a common boundary fence problem: one side receives the finished face while the other side sees rails, posts or a less attractive rear surface.

A purpose designed double sided panel can offer a consistent appearance to both properties. The fluted geometry also gives the fence more depth and allows it to function as an architectural landscape element rather than a purely functional divider.

For Australian projects, the product should be developed as a complete system, potentially including:

· lightweight double sided boards;

· aluminium or reinforced composite posts;

· top and bottom rails;

· plinth or retaining boards at ground level;

· concealed or coordinated fasteners;

· corner, end and gate details;

· installation guidance for different wind regions.

The marketable product is not merely the board. It is a repeatable fence system.

Wind Testing Must Cover the Complete Fence

Composite manufacturers may already have wind load test reports for boards, posts or previous WPC fence systems. These documents can provide useful technical evidence, but they do not automatically establish the design capacity of every new fence configuration.

The source material for this article identifies existing records for WPC fence wind load testing, composite post fence testing and acoustic testing. It also correctly notes that these reports cannot automatically be converted into the final wind rating required for a specific Australian project.

A credible vertical ASA fencing package should ultimately connect the test evidence to the complete configuration, including:

· panel dimensions;

· board orientation;

· post centres;

· rails and brackets;

· fastener type and spacing;

· footing assumptions;

· maximum fence height;

· design wind pressure.

For higher risk or non standard sites, a qualified local engineer should verify the system against project conditions.

ASA Wall Cladding: An Opportunity Beyond New Build Facades

The opportunity for ASA is not limited to standalone fencing.

One practical route into the Australian market is to use composite wall cladding as a decorative layer around structures that already perform the primary enclosure or boundary function.

Potential applications include:

· cladding installed on one side of an existing Colorbond fence;

· exterior finishes for prefabricated or modular buildings;

· outdoor television and entertainment walls;

· garden feature walls;

· fluted wall panels;

· two colour architectural elevations.

This approach does not require ASA cladding to replace Colorbond’s basic boundary function. Instead, the metal fence can continue to provide the established enclosure system while the composite surface provides a visual upgrade.

It also allows a project to manage its budget selectively. Decorative cladding may be installed only on the side facing a courtyard, pool, entrance or entertainment area rather than across the entire property boundary.

For this reason, phrases such as composite cladding for Colorbond fences may describe a more realistic market entry point than simply promoting a complete “Colorbond replacement.”

Fire and Bushfire Claims Require Product Specific Evidence

Fire related language requires particular care in Australia.

The National Construction Code references AS 3959:2018, incorporating amendments, for construction in bushfire prone areas. The applicable requirements depend on factors including the site’s Bushfire Attack Level, building classification, state provisions, component location and approved construction solution. A project being located in a bushfire prone area does not mean that every fence or cladding product automatically requires the same BAL classification.

Likewise, an ordinary ASA product should not be marketed as automatically achieving BAL 29 or a European Class B fire classification.

Where Mexytech’s NovAScend formulation is proposed for a fire sensitive project, the relevant EN 13501 Class B report should be linked to the exact tested formulation and product construction. The result should not be extended to unrelated ASA profiles, colours, cores or installation systems without supporting evidence.

For building cladding, buyers should also confirm whether the proposed assembly is affected by NCC requirements concerning non combustible external walls or ancillary elements. These requirements can vary significantly between a low rise residential feature wall and an external wall in Type A or Type B construction.

The correct sales process is to ask for the project specification first and then provide the relevant product specific documentation.

Australian Buyers Need More Than a New Profile

Even a well designed product can struggle if the channel cannot stock, display, install and reorder it efficiently.

The 2023 customer and distributor feedback identified several recurring priorities.

Local stock and reliable replenishment

Distributors may be reluctant to carry large quantities of an unfamiliar fencing system. A local agent, warehouse arrangement or dependable replenishment programme can reduce the risk of trial orders.

Spare posts, rails, caps and individual boards are particularly important. A fencing system becomes difficult to recommend when a distributor cannot quickly replace one damaged component.

Physical displays and samples

Composite colours and textures are difficult to evaluate through a digital image. Distributors need:

· short display boards;

· colour samples;

· installed corner sections;

· post and rail cross sections;

· examples of both sides of a double sided panel;

· comparisons between matt, brushed and embossed surfaces.

A small installed display can communicate the product more effectively than a catalogue containing dozens of profiles.

Installation efficiency

Australian labour costs make installation time an important part of the total project cost. A lightweight product will not succeed if it requires complicated measuring, excessive drilling or unfamiliar site fabrication.

The system should therefore include clear guidance for:

· post setting;

· maximum spans;

· board fixing;

· vertical alignment;

· thermal movement;

· cutting and edge treatment;

· gate integration;

· plinth board installation.

Videos, diagrams and concise installation manuals can help distributors train builders without requiring extensive factory support for every project.

Packaging for distribution

Packaging should support mixed orders and small project sales, not only full container efficiency. Distributors may prefer packs that can be opened and sold in manageable quantities without damaging the remaining boards.

Labels should identify the profile, colour, batch and length clearly so that repeat orders can be matched.

Quality documentation

Professional buyers may ask about dimensional tolerances, core visibility, water resistance, surface stability, colour variation and batch consistency.

Manufacturers should provide reports and samples corresponding to the product being quoted, rather than relying on a general corporate test library that includes different profiles or formulations.

Where ASA Composite Fencing Can Compete Most Effectively

Based on the material and channel gaps, five initial segments appear more realistic than the mass market boundary fence category.

Premium residential privacy fencing

Customers who dislike an industrial metal appearance may accept a higher price for a warmer architectural surface, particularly around courtyards, pools and landscaped outdoor living areas.

Double sided neighbour fencing

Where both sides of the boundary remain visible, a double sided design can provide a clear advantage over systems with a recognisable front and back.

Vertical architectural fencing

A purpose built lightweight vertical system can target projects where conventional WPC is considered too heavy and PVC does not provide the required appearance.

Hospitality and commercial landscapes

Hotels, resorts, restaurants and commercial courtyards frequently use fencing as part of the overall design concept. Texture, colour and coordinated cladding may matter more than achieving the lowest material price.

Decorative cladding over existing structures

Using ASA wall cladding to upgrade selected sections of Colorbond fencing, prefabricated buildings or outdoor feature walls can reduce the adoption barrier. The customer keeps a familiar underlying structure while adding a differentiated surface where it has the greatest visual impact.

What Australian Buyers Should Request from a Composite Fence Manufacturer

Before specifying a vertical ASA or WPC fence, buyers should request information for the complete proposed system:

1. The exact weight per linear metre or square metre—not only material density.

2. Recommended maximum fence height and post spacing.

3. Drawings of the top rail, bottom rail, posts, connectors and foundations.

4. Wind load evidence matching the proposed orientation and dimensions.

5. Thermal movement and expansion guidance.

6. Product specific weathering, colour and mechanical test reports.

7. Fire documentation for the exact formulation when required.

8. Installation instructions and cutting recommendations.

9. Packaging quantities and availability of replacement components.

10. Local inventory, lead time and warranty arrangements.

These questions help separate a market ready fencing system from a board profile that has not yet been engineered for local installation conditions.

Conclusion

The Australian fencing market is not a simple contest in which Colorbond wins and WPC loses.

Colorbond succeeds because it combines standardisation, established distribution, familiar installation and recognised performance. PVC succeeds where lightweight vertical construction and convenience are priorities. Timber remains familiar and adaptable. WPC provides timber like texture and a premium appearance, but its weight, price and longer education cycle restrict its use.

ASA composite fencing has an opportunity when it combines advantages that are rarely available in one system:

· lightweight construction;

· purpose designed vertical installation;

· an attractive finish on both sides;

· fluted architectural profiles;

· deeper timber inspired surfaces;

· coordinated fence and wall cladding options.

For Mexytech, the strongest strategy is therefore not to present ASA as another name for WPC or as a universal Colorbond alternative. It is to develop complete, tested and channel ready systems for the project categories that mainstream materials do not fully satisfy.

Frequently Asked Questions

Q: Why is Colorbond so popular in Australian fencing?

Colorbond benefits from an established supply network, standardised components, familiar installation practices and low maintenance positioning. Genuine COLORBOND® steel fencing is also backed by a 15 year BlueScope warranty, subject to the applicable conditions.

Q: Is WPC fencing suitable for Australian homes?

It can be suitable, particularly for premium privacy fences, front yard features and landscaped outdoor areas. The complete system must be selected according to fence height, wind conditions, post spacing, foundations and installation details.

Q: Can WPC fencing be installed vertically in Australia?

Yes, but a board should not simply be rotated from horizontal to vertical without checking the supporting system. Vertical installation requires correctly designed posts, top and bottom rails, connectors and foundations.

Q: What is a double sided composite privacy fence?

It is a fence designed to provide an attractive finished appearance on both sides. This is useful for shared boundaries, courtyards and commercial spaces where the rear of the fence remains visible.

Q: Is ASA fencing lighter than WPC fencing?

Some lightweight ASA co extrusion structures can have a lower density than conventional WPC. Buyers should compare the actual weight of the selected profiles rather than relying on general material density figures.

Q: Can ASA composite fencing replace Colorbond?

It can replace Colorbond in selected design led projects, but it should not be presented as a universal replacement. Its strongest advantages are architectural appearance, lightweight vertical options and double sided privacy designs rather than lowest price boundary fencing.

Q: Can composite wall cladding be installed over Colorbond fencing?

It may be possible to install decorative cladding against an existing metal fence, provided the supporting structure, fasteners, wind loads, clearances and thermal movement are properly considered. The installation should be designed as a system rather than attached without structural review.

Q: What should Australian buyers request from a composite fence manufacturer?

Buyers should request system drawings, profile weights, installation instructions, wind load evidence, weathering data, fire documentation where applicable, warranty terms and information about local replacement parts.

Q: Does an ASA fence automatically have a BAL 29 fire rating?

No. ASA is not automatically BAL 29 compliant. Bushfire suitability must be established using evidence relevant to the exact product, assembly, installation and project requirements.

Q: What is the difference between WPC fencing and PVC fencing?

WPC typically offers a denser timber like appearance but is generally heavier. PVC is lighter and convenient for vertical installation but may have a more visibly plastic surface. ASA composite systems aim to combine lower weight with a matt, textured and more architectural exterior finish.
