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 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.


When you consider all the factors, EXPAN really measures up. More and more achitects, engineeers, developers and owners are coming to the conclusion that there's a new way of looking at timber construction - one that looks both to immediate concerns about speed, efficiency and economy, while also considering sustainability, lifespan and futureproofing.
