Available in a huge variety of shapes and sizes, over the last half century, timber roof trusses have evolved into many forms. The efficiency of the materials used to manufacture today’s roof trusses, and the speed at which they can be made have also hugely developed. Roof trusses are widely used in domestic building, while their popularity in commercial builds continues to grow steadily.
Our in-house, expert design team can work with you to best meet your requirements from the very start of your project. The key thing is to ensure the accuracy and precision of your design, to avoid costly mistakes. We liaise with builders, architects, and project managers throughout the entire process to make sure your roof trusses are delivered on time, on budget and to your exact specifications.
Our roof trusses are available in a wide variety of shapes and sizes and can be customised to suit almost all roof designs. Your design will depend on your building shape and requirements. Some of the most common types are:
Kingpost Truss – suitable for spans up to 4.5 metres and used primarily in house and garage constructions
Queenpost Truss – spans up to six metres and mainly used for domestic structures
Fink Truss – spans up to 11 metres and the most commonly used domestic truss. The shape allows a water tank to be accommodated
Fan Truss – spans up to 16 metres and used mostly in large domestic dwellings and commercial buildings
Double W Truss – spans up to 16 metres. Popular in both commercial and domestic builds
Raised Tie Truss – applied to internal web structures to add extra headroom or provide an attractive architectural feature
Room in Roof (Attic) Truss – provides a structural roof and floor in one complete section and allows for additional space in the roof
Scissor Truss – features a sloping bottom chord to provide additional headroom and has a 15 degree difference between the top and bottom pitch
Modified Scissor Truss – shares the same detail as the Scissor Truss but with a flat section to it’s ceiling
Mono Truss – generally used for lean-to and hipped-end roofs. It can also be spanned onto fire walls or used back-to-back onto central corridor walls
Hip Truss – used in hipped roof construction. It can also be used for roofs which require a reduction in height for planning requirements
Lattice Truss – used in many situations including infilling large attic sections around dormers and stairs and for flat roofs.
There are several advantages for builders using trusses instead of stick framing:
- Designed and developed by engineers, roof trusses are constructed to meet all roof load and building requirements
- Overall construction time is significantly reduced as roof trusses are prefabricated
- Roof trusses are mostly built using two by four stock, which significantly reduces costs when compared to the longer framing pieces used in traditional stick roof framing
- Easy to install, today’s roof trusses can be installed by less experienced builders, saving on costs.
