s2 corporation pty ltd overviews corporation pty ltd overview

s2 provides technology solutions that can change the game.

s² and its precursor companies have evolved as a world leader in the provision of large span post-tensioned steel solutions. Across Australia, Asia and the Middle East, s² has built a legacy of highly efficient, pure space for aircraft hangars, industrial facilities, office buildings, sporting complexes, equine centres and industrial facilities.

Over 30 years of practical experience has been captured in a series of brands, patents, patent applications and know-how. Access to s2

intellectual property, technology and products is now available through Licencing.

Our pre-engineered solutions deliver vast, clear span structures that:

Use less carbon;

Save time right through the project life cycle;

Improve construction safety; and

Increase overall strength and structural performance.

The products available are called ptdome and ptarch, and incorporate clear spans from 25m up to 150m. Examples of both products are shown in this document.

The project history presented herein represents a resume of successful installations and outcomes, and contributed to the development of s2's product and Licence technology available todays2 s product and Licence technology available today.

the traditional approach

The longer the column free span of the structure, the more structural weight is necessary to control force and deflection and the greater the cost increase becomesbecomes.

This “Catch 22” situation intensifies the larger the span.

the s2 approachthe s2 approach

s2 is able to span large distances by replacing steel mass with “stored energy”.

Post tensioning of steel cables within the structurePost-tensioning of steel cables within the structure provides the storage mechanism. The higher the imposed loads associated with natural phenomenon such as earthquakes, tornadoes and snow loading, the q gmore cost and strength benefit the technology provides.

Once a process of grouting and bonding of each section has been completed, the building is effectively “active” for its lifecycle without the traditional “dead weight” structure controlling the building’s force and deflection
