A trussed rafter is an engineered framework consisting of structural members forming triangles. The framework derives its inherent strength from this triangulation. The standard trusses are capable for storage and holding water tanks, both of which are considered when designing the trusses.
However, due to the commercial limits of available timber sections, transport limitations for length and height, and manufacturing limitations of the pressing machinery, there are restrictions on the physical dimensions of the trussed rafter. At A. C. Roof Trusses Ltd we can manufacture trussed rafters up to an impressive 17.5m overall truss length, and a height of 5.5m. It is possible to manufacture trussed rafters outside this range by manufacturing the truss in two or more sections and site-assembled to the required profile.
We would recommend that you contact one of our experienced designers as early as possible regarding the design of your roof. Our designers will work with you to reach the ideal solution.
Below shows a profile of a standard truss. This profile can be modified i.e. cantilevered, part profiled etc….
