As construction continues to demand greater accuracy, efficiency and reliability, engineered timber products are increasingly being specified where predictable structural performance matters.
J-Frame 08 and J-Frame 11 are designed to meet these demands, providing the consistency of laminated veneer lumber (LVL) across prefabricated roof truss and frame applications. Manufactured from engineered timber, J-Frame offers predictable performance and dimensional consistency, supporting accurate design and efficient production.
Integrated into leading truss design software
J-Frame 08 and J-Frame 11 are now available within Pryda and MiTek design software, allowing licensed truss and frame manufacturers to specify J-Frame directly within established design and manufacturing workflows.
For architects and designers, this provides greater confidence that specified structural timber can transition efficiently from design through engineering and fabrication. For manufacturers, it means J-Frame can be incorporated into existing systems without adding complexity to the production process.
Engineering support for confident specification
J-Frame is supported by an engineering package developed by PTL Structural & Fire Engineering, providing practical design information for a range of residential structural applications.
Resources include span tables covering:
- Beams
- Rafters
- Lintels
- Bearers
- Joists
- Studs
The information is aligned with NZS 3604 residential construction requirements, helping designers, builders and manufacturers make informed decisions when specifying J-Frame LVL.
Certified for truss and frame manufacture
J-Frame is approved for use in prefabricated structural roof trusses and frames when design and manufacture are undertaken by licensed truss and frame manufacturers.
Combined with design software integration, engineering support and the inherent consistency of LVL, J-Frame provides a complete structural timber solution that supports precision, efficiency and design flexibility from specification through to manufacture.
As Tauranga Truss & Frame’s Chris Hindrup says: “The consistency, reliability and structural performance of J-Frame have helped streamline our production process while giving us confidence in the quality of the finished product.”
J-Frame Beam Span Tables, Stud Tables and the J-Frame Design & Installation Guide are available from jnl.co.nz
