How the Borg Group is building on a trusted Australian brand. By Campbell McInnes
In an industry where reliability matters more than claims, Porta stands as a name builder’s already know and trust. Now backed by the Borg Group, that trust is reinforced by the scale, investment, and manufacturing depth of one of Australia’s most established family-owned industrial groups. By consolidating multiple timber and panel businesses under the Porta brand, Borg has expanded what the brand delivers without changing what it stands for, quality, consistency, and confidence on site. It marks a new chapter for Porta, uniting Australian manufacturing capability under one familiar name, purpose-built for the future of local construction.
Most enduring Australian manufacturing stories begin with people, persistence, and a willingness to back local industry. For the Borg Group, that story began nearly four decades ago on the Central Coast of New South Wales, when brothers John and Michael Borg started making kitchens in their parents’ garage.
From modest beginnings in 1988, the business grew steadily by focusing on quality, reliability and an ability to adapt as the building industry evolved. Early success in kitchens and cabinet doors led to investment in purpose-built manufacturing facilities, including the Charmhaven site for thermo-laminated doors and panels, followed by the establishment of the Somersby facility with melamine press lines in the early 2000s. Each step was driven by a clear philosophy: control customer outcomes through local manufacturing and invest for the long term.
Over time, the Borg Group expanded through a deliberate strategy of vertical integration. By acquiring and developing businesses across the timber and panel supply chain, Borg strengthened its ability to support Australian builders with consistent products, dependable supply and local expertise. Key milestones included the acquisition of the Oberon MDF facility in New South Wales, followed by further Carter Holt Harvey panel operations and the Colourpyne™ brand, significantly expanding the group’s manufacturing capability.
Today, the Borg Group stands as one of Australia’s most significant privately owned manufacturing businesses. Still family-owned at heart, it remains guided by the same values established in its earliest days and a strong commitment to Australian-made products.

ONE VISION, ONE BRAND: THE EVOLUTION OF PORTA
The next defining chapter in the Borg Group’s journey is the unification of several respected Australian building materials businesses under a reimagined Porta brand. Between 2024 and 2026, Borg brought together Porta Mouldings, Australian Panels, Dongwha Australia, Easycraft® and Carter Holt Harvey Plywood, consolidating decades of experience, technical knowledge and manufacturing capability into a single, cohesive offering.
This evolution reflects a clear vision for builders and designers who increasingly value simplicity, reliability and products that work together across an entire project. By unifying these businesses under Porta, the Borg Group has created a brand that offers structural solutions, panels, plywood, outdoor timber and finishing products under one trusted name.
Importantly, this is not a reinvention that discards the past. Each business brings its own heritage and strengths, built over generations of Australian manufacturing. Porta’s long-standing reputation in timber mouldings, Australian Panels’ leadership in engineered wood products and flooring, Dongwha’s softwood timber expertise and Carter Holt Harvey Plywood’s trusted plywood brands now operate as part of a broader, more capable whole.
A PROUDLY AUSTRALIAN MANUFACTURING NETWORK
Under the expanded Porta brand, manufacturing remains firmly rooted in Australia. Facilities in Oberon, Bombala, Myrtleford and Mount Gambier form the backbone of this national network, delivering products designed for Australian conditions and manufactured to Australian Standards.
From advanced MDF and particleboard production to sustainably sourced softwood timber and large-scale plywood manufacturing, these sites represent significant investment in regional communities, local jobs and long-term industrial capability. Sustainability is embedded across operations, supported by responsible forestry practices and recognised certifications such as FSC and PEFC.
For customers, the benefit is clear. Porta now represents more than a product range; it represents confidence in supply, consistency in performance and the backing of a group that understands Australian building from the ground up.

THE STRENGTH OF THE PORTA BRAND
Alongside the scale and capability of the Borg Group now sits Porta, a brand that already holds a strong and trusted position. Porta is widely recognised by builders, designers and specifiers as a name associated with dependable performance, consistent quality and products that work as intended on site.
For many in the industry, the Porta name already represents confidence. It is a brand that has earned trust through real-world use, where reliability matters more than marketing claims. That recognition made Porta the natural choice to become the unifying brand as Borg consolidated its timber, panel and plywood businesses.
This alignment brings together the heritage and trust associated with the Porta name and the manufacturing depth, investment and long-term vision of the Borg Group, setting a clear direction for the future of Australian building products.
PROUDLY AUSTRALIAN, PURPOSEFULLY BUILT
Backed by the Borg Group’s Australian- owned manufacturing network, Porta combines local production with national scale, reinforcing confidence in supply, compliance and long-term availability.
In an industry often shaped by global supply chains, Porta stands firmly as an Australian-owned and Australian-made brand. This matters not only from a national perspective, but on a practical level for builders and specifiers who value local knowledge and accountability.
Being Australian made means Porta is designed for local conditions, manufactured to local standards and supported by teams who understand the realities of Australian sites. It also means supporting local jobs, regional communities and skills that have been established, refined and built up over decades.
Porta’s purpose extends beyond manufacturing. The company is driven by a genuine passion for building materials and a belief that they should perform reliably for the life of a building. This philosophy is reflected in every part of the range, from structural flooring to finishing details.
At its core, Porta is reinforced with a purposefully curated range, selected not to overwhelm, but to deliver versatility, quality and lasting results. Sustainability is embedded in decision-making, ensuring that today’s builds do not compromise tomorrow’s resources.
EXPANDING THE RANGE: ONE BRAND, MANY SOLUTIONS
Under the expanded Porta brand, builders and designers now have access to a broader suite of products that work together seamlessly across a project. While further editorials will explore individual products in detail, the strength of the range lies in its breadth and coherence.
This expanded range reflects the consolidation of multiple Borg Group businesses under the Porta brand. By bringing structural panels, flooring systems, plywood, outdoor timber and finishing products together, Porta simplifies product selection while ensuring compatibility and consistency across a build.
Structural solutions form the core of the offering. Products such as STRUCTAflor®, STRUCTApanel®, STRUCTAframe™ and STRUCTAply provide strength, compliance and confidence from the ground up. These systems are engineered to meet Australian standards and perform reliably across residential and light commercial applications.
Alongside these are everyday building essentials, including MDF, particleboard and plywood solutions, accessories and components that support the work done on site every day. Outdoor timber products extend Porta’s reach beyond the building envelope, offering treated pine decking, fencing and sleepers designed to withstand Australia’s harsh conditions.
Together, these products allow Porta to support projects from structure to finish, from the unseen elements that provide strength to the visible details that define a space.

STRUCTAFLOR®: STRENGTH UNDERFOOT, TRUSTED FOR GENERATIONS
Among the expanded range at Porta, one product stands out as a true icon of Australian building: STRUCTAflor®. Backed by more than 50 years of use on Australian sites, STRUCTAflor® has earned its place as a benchmark structural flooring solution.
STRUCTAflor® is engineered for performance where it matters most. It provides a strong, stable and compliant subfloor that builders can rely on, project after project. Manufactured locally and designed to meet Australian Standards, it has become a familiar sight on residential and commercial sites across the country.
The popularity of STRUCTAflor® lies not only in its strength, but in its practicality. Builders value a product that installs efficiently, performs consistently, and stands up to real-world conditions. The distinctive tongue and groove system enhances stability at joints, creating solid, squeak-free floors that last.
STRUCTAflor® YELLOWtongue®, in particular, remains the builder’s first choice. At 19 mm thick, it meets load requirements for residential flooring and suits a range of installation methods, from platform construction to upper-storey floors. Its ability to withstand extended weather exposure during construction adds further confidence on site.
In an industry where time, compliance and reliability are critical, STRUCTAflor® continues to deliver exactly what builders need: proven performance without complication.
CIRCULAR ECONOMY
Porta’s aim is to create a circular economy, that wherever possible, waste is minimised, and resources stay useful for as long as possible. This approach is supported at a group level through Borg’s broader sustainability strategy, embedding circular economy principles across manufacturing, logistics and material recovery.
Unlike the traditional linear model of “take / make / use / throw away,” a circular economy follows a path of “reduce / reuse / repair / refurbish / recycle.”
One such example is reDirect Recycling, a company within the Borg Group, which delivers circular resource recovery solutions through a streamlined system designed to divert excess waste from landfill.
reDirect Wood Recycling manages the full waste lifecycle, from collection and transport through to the treatment of pallets, mixed clean timber, and particleboard off cuts. The objective is to transform discarded materials into new resources and return them to the market, reinforcing a circular economy. A significant proportion of the recycled wood is reused in particleboard manufacturing, demonstrating a strong commitment to sustainability and closed- loop solutions.

MEETING MODERN STANDARDS WITH CONFIDENCE
The Australian building industry is constantly evolving, and recent updates to the National Construction Code reflect a growing focus on liveability, accessibility, and long-term performance. Products such as STRUCTApanel® play an important role in meeting these expectations.
STRUCTApanel® offers strength, consistency and versatility across applications including wall linings, bracing, and flooring underlay. In particular, its role in reinforced wall backing for bathrooms and sanitary areas supports compliance with liveable housing design standards, ensuring homes are adaptable for changing needs over time.
This focus on futureproofing aligns closely with Porta’s broader philosophy. Compliance is not simply about meeting minimum requirements; it is about building homes that are safer, stronger and designed to last. By offering purpose-built solutions, Porta helps builders move beyond box-ticking and toward better outcomes for occupants.
FINISHING TOUCHES THAT DEFINE QUALITY
While structural elements provide strength, it is often the finishing details that define how a building is perceived. Porta’s mouldings range continues to play a vital role in elevating interiors, adding definition, protection, and character to spaces.
Architraves, skirtings, and decorative profiles do more than conceal joins. They frame rooms, protect walls, and contribute to a sense of completeness. In modern homes, slim profiles create clean lines and understated elegance. In more traditional settings, decorative mouldings add warmth and heritage appeal.
Porta offers both solid timber and pre- primed MDF options, giving builders and designers flexibility across budgets and styles. Timber mouldings provide durability and natural beauty, while MDF mouldings deliver stability, ease of installation and paint- ready efficiency.
These details matter because they signal care in construction. They enhance perceived value and contribute to long-term durability. With the Porta mouldings range, small details make a lasting impact.
PLYWOOD SOLUTIONS WITHIN THE PORTA FAMILY
The integration of plywood brands within the broader Borg Group further strengthens Porta’s offering. Products such as Ecoply® and Formrite® bring additional versatility to the range, supporting structural, exterior and interior applications. The inclusion of these products follows the Borg Group’s acquisition of Carter Holt Harvey Plywood, further strengthening Porta’s ability to deliver integrated building solutions from a single, trusted source.
Manufactured from sustainably grown plantation resources, these plywood products are trusted by architects, builders, and DIY professionals alike. Whether used for bracing, cladding, flooring, or decorative linings, they offer durability, strength and design flexibility.
By aligning these products under a unified group, Porta customers gain easier access to complementary solutions that work together across a project.
SHAPED BY HISTORY, BUILT FOR THE FUTURE
Porta’s story is one of growth and change. Under the Borg Group, Porta has entered a new era, bringing together some of Australia’s most trusted building brands together under one roof. From structural flooring to finishing details, the range reflects a deep understanding of how buildings are designed, built and lived in. With the backing of the Borg Group, Porta is supported by scale, deep technical expertise and a comprehensive product offering.
For builders, designers, and homeowners alike, the message is clear. A house of brands. One Porta. Building solutions you can rely on.
