Porta

Our story begins close to four decades ago, when brothers John and Michael Borg established a cabinet door manufacturing business on the Central Coast of New South Wales. From those early days, the business grew steadily, becoming now a trusted name in the Australian building industry by embracing innovation, navigating change and staying true to the values that shaped its foundations.

Today, our heritage enters a new chapter with the integration of Borg businesses, Porta Mouldings, Australian Panels, Dongwha Australia and most recently Carter Holt Harvey Plywood under an invigorated and redefined Porta. This now brings decades of experience, manufacturing capability and industry knowledge together under one trusted brand.

While the business has grown and evolved, it remains family-owned at heart. The values established from the very beginning continue to guide how we operate today and shape how we plan for the future. Our heritage is more than history; it’s the foundation on which Porta continues to build.

Porta is one of Australia’s leading suppliers of building solutions for residential and commercial construction. We are a trusted partner to builders, stockists and suppliers across Australia, known for consistent quality and support. Our focus is on progress, making it easier to build with confidence now and into the future.
