Triline cavity sliding door solutions offer a premium product and service.

Priding ourselves on continued repeat business from satisfied clients who work with us on regular basis for commercial and residential projects around Australia.

The idea for Triline Quality Door Systems was born in 1996 when founder and home builder, Stuart Colledge, noticed that there was no easy way to obtain pocket sliding doors in Tasmania. After a few years of extensive product research, design and development, Triline launched its first cavity sliders in a leading hardware store in Hobart. Over the next eight years our output increased steadily and by 2004 we outgrew our facilities. 2005 saw us expand to a larger premises and, as a result, we have significantly increased our production output.

With more space and the passion to go further, we overhauled and re-designed our cavity pocket system. After much refinement and consultation with our customers, the Phoenix™ cavity slider was formed. We continue to grow and improve our product range to give our customers more options and avenues for creative exploration in internal sliding doors. We also seek ways to better construct our cavity sliding doors to ensure our customers have the latest in architectural design and material performance.

Our custom-made, high-quality door solutions are expertly crafted in Tasmania, catering to clients throughout Tasmania and Victoria.

Since Triline was launched in 1996, and as we have grown over the past 25 years, we have kept our production sites local. Based in Hobart, and now also in southern Queensland, we are proud to keep our operations in Australia as we have expanded production to provide our product range across the country.

We consider it vitally important to keep our high-quality standards by creating our own custom-made products in the same premises that our head office and staff operate from.

We have 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.

Having experience from building homes and working with joinery, the expertise behind the Triline cavity slider has been crafted from the builder’s perspective when it comes to ease of installation, and functionality, when it comes to the homeowner’s day-to-day experience.

It is important to us that we put extra care and attention into providing a sliding door solution that is durable and one that will stand up to the test of time. Considering doorways are used on a daily basis to move from one space to another it is important to consider the quality of the door product being chosen to fill these spaces.

This is where we can provide you with peace of mind when choosing Triline sliding door systems.

Custom Work

At Triline we love to take the journey with our customer from the initial thought process, through design and manufacture stages, all the way to installation of your internal sliding door. Although this may sound like a simple process there are essential communication steps we like to take along the way with specifiers, builders, and, most importantly, the property owner, to ensure we deliver the perfect solution for your project every time.

Dream. Design. Deliver.

Triline not only aims to construct aesthetically appealing custom sliding doors, but also to deliver bespoke products that are built to last.

Using custom internal sliding doors gives you the opportunity to have your doorways designed perfectly in line with your creative vision, making your sliding doors a unique statement to any room. Having your sliding doors made to measure is also a great way to use the space you have available. Whether it be a modification to suit a current room or a new build, we strive to provide you with the perfect solution to meet your needs. Our sliding door systems and accessories make fantastic additions to any doorway, as they give it a polished, yet unique look.

Having been in the sliding door manufacturing business for over 20 years, we have gradually extended our product range to include custom made doors to complement our cavity sliders. These include Hollow Core, Semi-solid Core, Solid Core, and the unique Kit-form door. In acquiring your door from us to suit your custom cavity unit, you can be assured of the perfect fit and required rebates already done for ease of installation. Triline puts the same attention to detail and excellent workmanship to use when constructing bespoke sliding doors for our clients as we do with our standard units.
