PRODUCTS AND SERVICES
TIMBER WALL FRAMES
Manufactured from graded structural timber and engineered wood products, our timber wall frames are designed to safely transfer vertical and lateral loads to the foundation. Each frame typically includes studs, top and bottom plates, noggings, lintels, and bracing components to ensure structural stability and accurate load paths. All systems are designed in accordance with relevant standards. Lightweight, durable, and cost-effective, prefabricated timber wall frames help Illawarra builders reduce construction time while ensuring reliable structural performance.
Our wall frames are:
- Manufactured using MGP10 graded structural timber
- Designed in accordance with AS1684 Timber Framing Code
- Engineered bracing systems for structural stability
- Stud configurations suited to project requirements
- Designed for local wind classifications (N2–N4 and C classifications where applicable)
- Bushfire (BAL) design considerations available where required
TIMBER ROOF TRUSSES
We manufacture durable, precision-engineered timber roof trusses designed to optimise load distribution, span capability and construction efficiency. Roof trusses eliminate the need for internal load-bearing walls in many designs, providing greater flexibility for open-plan layouts and modern architectural styles. Using advanced detailing software, each truss system is designed for strength, precision and compliance with Australian building requirements. At Wonson Frames & Trusses, we supply durable king post, queen post, and scissor trusses, engineered for strength, precision, and compliance with Australian and NSW standards. Each truss is manufactured to match project specifications, roof pitch and span requirements.
Our roof trusses are:
- Designed to meet relevant Australian Standards
- Load calculations and structural verification
- Wind rating compliance based on site classification
- Engineered for long spans and efficient material usage
- Compatible with a wide range of roof profiles
TIMBER FLOORING SYSTEMS
Our timber flooring systems are engineered to provide strong, stable foundations for residential and multi-residential construction. Designed to safely transfer loads to walls, beams and foundations, our prefabricated systems improve installation speed and structural performance.
By integrating engineered timber components, we provide flooring solutions that reduce shrinkage, increase span capability and enhance overall build quality. Flooring Components include LVL beam, Engineered I-joists, Bearers and joists, Rim boards and Structural subfloor sheeting.
These components work together to create a stable and efficient flooring structure tailored to project requirements.
Our flooring systems provide:
- Longer spans with reduced deflection
- Improved dimensional stability
- Reduced material waste
- Easier integration of plumbing and electrical services
- Enhanced acoustic and energy efficiency performance
FREE IN HOUSE ESTIMATES AND DETAILING
At Wonson Frames & Trusses we offer precise in house estimates and detailing using the advanced MiTek design system, ensuring your timber framing, roof trusses, and flooring projects are accurately planned and costed. The MiTek system allows our experienced team to produce detailed 3D drawings, load calculations, and material schedules, giving builders and homeowners confidence in the structural integrity and efficiency of their project. By handling estimates and detailing in house, we streamline communication, reduce errors, and optimise material usage, saving time and costs on site. Whether you need king post, queen post, scissor trusses, or full wall frame systems, our MiTek based process delivers accuracy, compliance with NSW & Australian standards and a smooth build from start to finish.
Our inhouse detailing team provide:
- Architectural plan review
- 3D structural modelling and detailing
- Load calculations and wind classification checks
- Material optimisation and compliance verification
- Manufacturing in our Tarrawanna facility
- Coordinated delivery scheduling to site
