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


Timber-Concrete-Compostie floor systems are relatively new to Australia and New Zealand and satisfactory performance requires a rigorous design procedure address both ultimate and serviceability limit stages. TCC structures have a degree of complexity since they combine two materials that have very different mechanical properties and respond in different ways to the environment. A complete Expan Design Guidelines for TCC Quiet Floors is in production now for release shortly to address many of the questions around using this product.


It is unquestionable, however, that Expan Quiet Floors offer a quick, easy and feasible solution for flooring - especially in open plan multi-storey buildings.
