The design and engineering of trussed rafter roofs allows cost-effective and rapid construction of almost any ‘roof-scape’. A wide variety of truss rafter profile types have evolved to solve almost every building design requirement. Comprehensive roof layout drawings and details are tailored to the exact requirements of individual projects. The wide variety trussed rafter types offer more economic solutions than traditional framing methods. Complex roof structures such as hips can be modelled, tested and manufactured from the minimal material required.
There are a number of truss rafter profiles or configurations which have been adopted as common or standard. For example the most frequently used is the fink roof truss recognised by its distinctive W-shaped internal web pattern. Over a significant range of spans the fink roof truss configuration is the most cost effective.
