First in WA

Colli Truss and Frame are the first Western Australian timber and building supplier to offer the unique Floor Cassette System to the WA building industry.

Unique Floor Cassette Systems

Floor Cassette Systems are a fast and safe method of structural erection that results in a significant reduction in construction programing and in turn development costs.

Floor Cassette Systems are lighter than reinforced concrete so mobile cranes can be used to erect the cassette panels, which results in substantial savings in both the erection process and skilled labour costs.

Floor Cassette Systems are a versatile building system that offers engineers and architects flexibility in design with long spans and the ability to use the panels for all floor assembly types just by varying the panel thickness. Floor Cassette Systems also offer substantial environmental benefits such as long-term carbon absorption through the utilisation of timber.


Floor Cassette Systems are a flexible and light-weight building system that allows for long spans for floor construction. The panels are precision designed and fabricated in accordance with your specification.

Set Downs

Wet area and balcony set downs can be incorporated into the Floor Cassette Systems which saves even further on site labour and fabrication time.

Service Integration

The unique design of the TecBeam floor joist allows for the services to be incorporated within the construction depth of the Floor Cassette Systems. This service integration significantly reduces the overall construction depth of the overall system and in turn maximises floor to ceiling heights.

Detailed Design and Drafting

The Floor Cassette System utilises a detailed design and drafting service which ensures that every component of the cassette system is incorporated into the overall design of the project. Coordination with the supporting structure, architectural layout and service design is carried out prior to the fabrication of the cassettes which ensures that a seamless installation process is achieved on site. Engineering design and certification of the Floor Cassette Systems can also be provided if required.

So whatever the project requirement is, you can be sure that Colli Truss and Frame can handle the job, leaving you to concentrate on more pressing issues.
