ptdome incorporates leading edge structural design and materials with innovative manufacturing and erection methodologies.  It benefits from s²'s patented post-tensioned steel technology and delivers unparalleled strength and flexibility of use for a roof product of this size. 

It has applications across numerous market sectors including aviation, sport and recreation, disaster relief, mining and military.

ptdome is available in 5m incremental sizes ranging from 25m x 25m (625m²) up to 50m x 50m (2,500m²) and requires only four corner columns.  This means you can have a 35m x 40m ptdome, or a 25m x 45m ptdome, and so on.

ptdome is manufactured from a range of high quality steel products and comes clad in either ribbed profile steel roof sheeting or high quality, UV resistant PVC coated fabric membrane. 

Façade systems, doors and ventilation options are available on request to create a fully (or partially) enclosed column-free facility.  All members and connections have been standardised right through the product range to bring efficiency through the manufacturing, delivery and assembly process.

ptdome has been designed to be rapidly assembled and installed on site at ground level without the use of cranes, heralding a new era in OH+S practices on a construction site. 

A standard 25m x 25m ptdome can be fully assembled and erected in 5 days or less (without walls) once the four foundations are in place.
