New Zealand builders have used prefabricated roof trusses for decades. The builders who use these trusses praise their many advantages, including:

  • excellent value
  • standard compliant design that puts their mind at ease
  • flexible design
  • easy installation

With trusses, it is easy to achieve long spans without spending a lot of money. Truss spans can be as long as 15 metres without requiring any internal support. Most open plan homes benefit from this kind of value.

If a cove truss is used for the ceiling line, it can often necessitate large top chords and create obvious deflections.

Scissor trusses offer an alternative and a few advantages over cove trusses. These include smaller-sized timber,  and longer spans.

Every truss is made to meet unique design specifications,engineered to support the specific loads placed upon them. Our manufacturing process makes the most efficient use of timber and ensures minimal timber wastage.

A large number of home designs benefit from roof truss designs, saving their owners money compared to other timber alternatives.

Compliant Design

Pryda products all adhere to very strict design requirements. By using a standardised set of in-house quality assurance systems and software design solutions, we ensure the quality and regulatory compliance of our products. There are numerous benefits to our strict design process:

  • It removes the need for our customers to hire designers and product engineers to create very detailed reports for all the components to be used in the wall, roof and floor components. Our own licensed fabricators can provide this service for you.
  • In many cases, the building authority can issue consent with only the documents that we have delivered to you. You may not need to pay a third party contractor for certification.

Pryda Products Are Used Everywhere

Licensed Pryda fabricators use our Pryda Build software in order to create designs and determine specifications for numerous components that are used every day in industrial, commercial and residential buildings. These include both joined and unjoined steel and timber items. For every timber component we produce, we ensure the design specifications are individualised for the specific structure and load they are going to support.

Independently Assessed

On a regular basis, Pryda Build is assessed by independent structural engineering consultants. They determine our compliance with New Zealand design standards and the New Zealand Building Code.

Pryda Build software abides by all established building code requirements, including those in the following documents:

AS/NZS 1170 Structural design actions


We Provide Documentation

Using our software, truss fabricators can easily access any of the following documents:

Plan Layout: Details all truss connectors, the layout of the roof and all trusses and all bracing; comes with notes explaining installation

Producer Statement Report: Shows compliance with regulations for the entire project and includes BCA document references

Detail Sheet: Detailed drawing of every truss as well as all the design parameters that relate to that truss

Design Report (summary): Includes all applied distributed loads, all the general loads, support reactions, requirements for bearings, design details for critical member timber, as well as critical joint nailplate designs

Design Report (detailed): Includes all content from the summary report as well as an analysis of the most important combined load cases; designs for all timber members; designs for all nailplate joints

Flexible Design

A key benefit of both roof and floor trusses is that they can be  designed to accommodate most air conditioning units, skylights, hot water heaters and various other roof features as well as box gutters and coffered and raked ceilings.

Easy to Install

Trusses designed and manufactured by Pryda Fabricators  can decrease installation time as  they are designed specifically for each job our customers need them for. That not only decreases how long it takes to install them but also lowers the risk  of theft on-site.

To make sure roof planes maintain their uniformity, all trusses are crafted in precision jigs.

While stick-built roofs come in multiple parts, all supplied by a variety of distributors, our fabricators supply trusses in a single package. This decreases the amount of time it takes to install  them.

In addition, as trusses are manufactured off site, the impact of inclement weather or on site space restrictions is minimised helping builders complete the job faster.

Finally astrusses are delivered to the customer’s site and stacked above the wall frames and the design is job specificthe risk of theft is minimised.

Trusses are design specific for each house so its is uncommon for trusses to be stolen from site. They are often delivered to site and stacked on top of the wall frames.
