Bringing all the strength and endurance of steel to the sustainability and flexibility of wood, the Expan prefabricated construction system brings timber into the commercial and industrial design age.

Expan’s totally prefabricated technology cleverly embeds post-tensioned tendons into timber to lock the system together. The range includes revolutionary timber frame, wall and floor systems and quick-connect portal frames.

The result is a cost effective, time efficient, system that opens new doors in design and construction of commercial and industrial buildings.

With Expan, you can use engineered timber framing to create wide open spaces and building layouts with flexibility like nothing before – without the need for closely spaced columns or walls.

Expan Quick-Connect Portals

Expan Quick-Connect Portals provide an easy and cost effective way to fabricate and erect long-span engineered timber portal frames for single storey and industrial buildings.

Using the Quick-Connect technology results in simple and standardised knee, column-to-foundation, rafter splice and apex connection designs and minimises on-site erection times and costs

Expan Quiet Floors

Expan Quiet Floors provide a modular and cost effective flooring system for open plan multi-storey buildings.

The floor systems have been developed to provide a robust structural solution, minimise inter-floor air-borne noise transmission and a dynamic vibration characteristic that is comfortable to occupants.

Current Expan Quite Floors are Timber-Concrete-Composite (TCC) designs and future options will include all timber options

Expan Frames and Walls with Pres-Lam technology

Expan Frames and Walls provide an easy and cost effective way to connect long-span, large-scale engineered timber elements to form open plan multi-storey buildings.

Using the post-tensioned timber technology results in simple and standardised connection design and minimises on-site erection times and costs.

Horizontally post-tensioned frames in one direction can be combined with vertically post-tensioned walls in the other direction to provide structurally efficient lateral restraint to buildings in both directions. Alternatively, vertically post-tensioned walls can be incorporated in both directions, providing the required bi-directional lateral restraint.
