Pre-fabricated timber Roof Trusses have been part of Australian building practices for over 30 years.

They are: Cost effective, certified and manufactured in accordance with strict building standards, they have design flexibility, and are easy to install.

Long clear spans can be achieved at an economical rate. Trusses can easily span 10-15 metres or more without the need for internal supports. This is particularly useful for ‘open plan’ designed homes. Using such truss types as Scissor Trusses allow for the use of smaller timber sizes, minimal deflections and longer spans.

Individually engineered optimising the timber truss components to suit the design loads applied to them. The manufacturing of trusses optimises timber stock which leads to minimisation of timber waste. There are many home designs which are conducive to roof trusses and deliver an overall cost saving compared to a traditional stick-built roof. However should you prefer a stick frame we will be happy to oblige.

There are stringent requirements associated with the development and use of our design software, which alleviates the need for designers and project engineers to prepare detailed specifications associated with the roof, floor and wall components. Bretts are a licensed Multinail (Geebung) and Mitek (Hervey Bay) fabricator. Building authorities can often provide building consent based on the documentation supplied by Bretts, without the requirement for independent third party certification, particularly in residential construction.

The software system used by Bretts produce designs and manufacturing specifications for joined and loose timber and steel components in the construction of residential and light commercial and industrial structures. All timber components and connectors are individually designed to suit the specific loading conditions for the structure. The software has been independently assessed by professional consulting structural engineers for compliance with the Building Code of Australia, BCA 2010, and its referenced documents.

Full documentation is available to support the manufactured trusses.

Easy to install Wall Frames, means site cost reductions.

Prefabricated timber wall frames offer many of the benefits associated with timber roof trusses. Manufactured off-site in our factories at Geebung and Hervey Bay, using state of the art software and manufacturing equipment. Our frames are delivered to site ready to install with clear installation instructions. The reduced on-site erection times lead to significantly reduced labour costs.

Prefabricated frames can also reduce the effect of wet weather delays. Frames are individually detailed and engineered which optimises the timber components to suit the design loads applied to them. Manufacturing of frames optimises timber stock, leading to minimisation of timber waste versus the on-site stick built alternative. However, as with your roof truss requirement, should you rather a stick frame we can accommodate you as well.

As part of a fully engineered system and a licensed Fabricator, we will ensure that the critical studs, wall plates, lintels (steel or timber) and various tie downs and restraints are designed to support the roof and upper storey loads. More importantly, the ‘right hand is guaranteed to be talking to the left hand’ with one entity (Bretts) overseeing the design and manufacturing of the entire system.

As a licensed fabricator we provide builders with their complete roof and wall framing requirements as part of a fully engineered system including lintels and beams. Many builders we deal with are moving towards the construction method of timber frames with cladding, as a result of increased pressure for faster and more affordable building methods. Using James Hardie, Weathertex cladding or timber cladding for example, provides flexible design options with a host of other benefits.

Cost effective Floor Truss Systems, no cutting, drilling or notching, set-downs and recesses included where needed, greater design flexibility, equals site cost saving.

Our Floor Truss systems have been proven over many years to provide occupiers with floors which have excellent reliable performance. The timber for these provides a stable platform during installation and minimizes the overall depth required. All trusses use commonly available timber, our floor trusses are mostly manufactured using 70 mm or 90 mm dry structural pine. There are two different types of web systems for these trusses. Both have timber chords but the Longreach Systems use all-timber webs, while Span Systems use metal webs for the diagonals and timber webs for the verticals.

Longreach Trusses, are a premium performance product using nail-plated, all-timber trusses of any depth, but typically 300 mm deep for residential floors and 400 mm deep for commercial floors. Longreach trusses are referenced as FT200, FT250, FT300, FT350 and FT400, where “FT’ means Floor Truss, and “200” is the nominal overall depth (mm). The actual depth dimensions are in nominal size steps, or may be individually specified as required for the particular project.

They can be designed for all common floor loads, including commercial loadings up to 5 kPa or point loads up to 6.7 kN. These trusses are slightly heavier than normal span trusses and being all-timber generally have a stiffer performance as they can dissipate floor vibrations very well, while the nail-plates connecting the webs and chords are quite substantial.

Our Floor Truss Systems offer many benefits to the designer, the builder and the building owner in providing a reliable high performance system for both domestic and commercial construction. The use of the our Floor Truss System results in a very cost effective, high quality product that is sufficiently flexible to accommodate the most complex of building requirements.

These fully engineered open-web timber floor truss systems with timber webs (Longreach) or metal webs (Span) have many advantages that result in a lower net installed cost compared to other systems that are available. In some instances there may be a material cost increase by using floor trusses over alternative flooring systems. However, when it comes to installing the product floor trusses can provide significant labour savings. In addition, floor trusses have some considerable design advantages that could result in reducing the need for a large amount of costly structural support construction, e.g. Long spans may reduce the need for internal load bearing walls.
