Frame & Truss

What We Provide

Prenail Frames & Trusses

Expertly designed and fabricated off-site for fast, efficient installation on-site. Our frames and trusses are crafted for strength, accuracy, and long-lasting performance.

Exposed / Feature Trusses

Exposed trusses combine aesthetic appeal with structural function, adding a striking architectural feature to your build. They are ideal for open-plan living spaces, halls, and feature ceilings.

Engineered Beams

We supply engineered timber beams including LVL, glulam, and flitch beams—ideal for long spans and heavy loads. Each beam is tailored to your project’s structural needs for optimal performance and flexibility.

Detailing & Support

Our in-house detailing team uses Mitek software to provide comprehensive documentation and shop drawings. This ensures absolute accuracy from design through fabrication, helping your project stay on track and within spec.

Mid-Floor Cassettes

Pre-manufactured for speed, strength, and efficiency. Our mid-floor cassettes are built off-site in a controlled environment, then delivered ready to install, reducing on-site labour, improving safety, and keeping your build moving forward. Designed for structural integrity and fast crane placement, cassettes allow quicker floor closure, enabling upper-level work to begin sooner. Precision-built to spec, they also help minimise material waste and eliminate rework on site. An ideal solution for multi-level builds, mid-floor cassettes streamline your project from the inside out.
