Timber Frame & Roof Truss Manufacturing Specialists
At Wonson Frames & Trusses, we manufacture high-quality prefabricated timber wall frames, engineered roof trusses and flooring systems designed for residential and multi-dwelling projects across NSW. Every frame and truss package is produced in our Tarrawanna facility using precision detailing software and modern prefabrication techniques to ensure accuracy, strength and on-site efficiency.
Our wall frames are built for structural reliability and fast installation, while our engineered roof trusses are designed to suit a range of roof profiles, spans and load requirements. We also supply durable flooring systems engineered to meet performance standards and project specifications.
All components are manufactured in accordance with relevant Australian Standards, including AS1684 timber framing requirements. Designs consider local wind classifications, site conditions and, where required, bushfire (BAL) compliance to ensure suitability for regional environments across The Illawarra, Southern Highlands, South Coast and Sydney.
Our focus is delivering structurally sound, compliant timber framing solutions that support efficient construction timelines and long-term performance.
