Prefab Technology Pty Ltd supplies custom-made floor trusses, including Posi Strut open-web systems, to builders and owner-builders across Melbourne and Victoria. Manufactured at the Croydon South facility using Pryda design software, every truss is engineered to your specific project plans before delivery direct to site.

Open-Web Design for Easy Services Integration

Open-web floor trusses simplify the installation of plumbing, electrical wiring, and HVAC ductwork. The open panels between timber chords allow trades to route services straight through the floor zone without drilling or notching structural members, reducing rework and multi-trade coordination time. For Melbourne residential and dual-occupancy builds where wet areas, hydronic heating, and ducted cooling are increasingly standard, this routeing freedom can meaningfully reduce on-site labour.


Key advantages of Posi Strut open-web floor trusses include the following:


   ▸ Long, clear spans that can reduce or eliminate intermediate load-bearing walls, supporting open-plan layouts.

   ▸ A built-in service void allowing plumbing, electrical, and HVAC systems to pass through without cutting or notching.

   ▸ Lightweight construction relative to span depth, making on-site handling more manageable.

   ▸ Consistent factory-engineered profiles that reduce fitting variations on installation day.

   ▸ Compliance with Australian building requirements when designed through accredited software systems.

How Custom-Made Floor Trusses Are Manufactured to Specification

Custom-made floor trusses from Prefab Technology Pty Ltd are produced through a structured, software-driven process at Croydon South. As a licensed Pryda fabricator, every design is modelled using Pryda's specialist software before a single piece of timber is cut, so set-downs, cantilevers, and concentrated load points are resolved at the design stage rather than on site. Engineering computations can be provided to assist with permit applications. Completed trusses are matched to your site layout and delivered across Melbourne and Victoria ready for installation.

    I have been a registered builder for over 40 years and one company that I know I can count is, Prefab Technology. The level of quality and customer service is excellent and their pricing is competitive. I especially value Carlo’s on site measure and check. We will always use Prefab Technology for our truss and framing needs.

    I would like to take this opportunity to thank the entire team at Prefab Technology for their professionalism and extraordinary business skills on all levels. They are great at giving professional advice, great customer service and great at going above and beyond accommodating all concerns that do arise during design and construction of the timber framing.

Custom-Made Floor Trusses for Melbourne FAQs 

  • What Is the Difference Between a Posi Strut and a Standard Floor Truss?

    A Posi Strut uses timber chords with pressed-metal webs, creating open panels for services. Solid timber joists lack this void.

  • What Spans Can Open-Web Floor Trusses Achieve?

    Spans depend on depth, timber grade, loading, and spacing. Open-web trusses achieve longer spans than solid joists, confirmed during design and quoting.

  • Can Services Like Plumbing and Air Conditioning Run Through the Floor Trusses?

    Yes. The open-web design lets plumbing, electrical, and HVAC pass through the truss depth without cutting, preserving structural performance and trade efficiency.

  • What Is the Turnaround Time for Custom Floor Trusses?

    Turnaround varies by project complexity. Prefab Technology Pty Ltd aims for fast turnaround and will discuss programme requirements when you request a quote.
