Space Is Precious. Create More.

Doors are the gateways within your home.

They are a way to signal closure or to welcome something new. 

Nowadays, doors are a key element in any interior design project. The quality of interior doors affects a building’s functionality and accessibility to a great degree, but functionality shouldn’t mean compromising on style.
Triline Quality Door Systems offer internal sliding door solutions that hold a seamless balance between functionality and high-class aesthetic appeal. Triline’s sliding doors can be found in several world-class developments across Australia.


Why Functional & Customisable Sliding Doors Are So Important To Us

In Hobart in 1996, as a home builder himself, Stuart Colledge realised there was no easy way to obtain pocket doors in Tasmania, which raised some difficult questions. This triggered the development of innovative cavity sliding doors.
After a few years of extensive product research, design and development, Triline launched its first cavity sliders in a leading hardware store in Hobart. During the next eight years, output increased steadily and the years 2008-2011 saw an overhaul and redesign of the
cavity pocket system.
After listening to the building site demands raised by different customers, the company refined and transformed the product into the Triline Phoenix cavity slider.

Since then, the company has continued to find economic, efficient and elegant solutions to internal sliding door challenges, extending the product range with systems such as the Zero Clearance sliding door system.
