ATDC’s installation of its parallel overhead tracking sliding door system at the Glue Store at Melbourne’s Emporium, offers huge space saving storage advantages.
This installation involves securing a 27 metre wide store frontage (at a height of 4m) and configuring the overhead door system in a way where, once unlocked and opened, it folds back to a mere 2m stacking area.
In order to achieve this, ATDC used its multi-panel S07-2 side-by-side-stacking overhead door system on a parallel top track and achieved a user friendly seamless lock up for the retailer through the use of its multiple intermediate up/down locking mechanisms.
For further information on a recent side-by-side project where ATDC utilized a triple track split option for even greater space saving advantages please see.
ATDC’s Side-by-Side overhead retractable door system is a groundbreaking solution in minimising storage space while maintaining simplicity in design. This system employs a straightforward configuration of parallel overhead tracks, either double or triple, coupled with a series of seamless up/down locking mechanisms. This innovative setup reduces the side stacking storage space required for these doors to a mere 6% of the overall opening span being secured. This space-efficient design is ideal for applications where space is at a premium.

Space Efficiency and Functionality
The key advantage of the Side-by-Side system is its ability to significantly reduce the footprint of the doors when retracted. This efficient design ensures that valuable floor space is not compromised, making it perfect for locations where space-saving is crucial. The seamless up/down locking mechanism enhances the door’s functionality, providing a smooth and secure operation.
Recent Installation at Oakleigh Gourmet Deli
A notable installation of ATDC’s Side-by-Side overhead retractable door system was recently completed at Oakleigh Gourmet Deli, located at Oakleigh Central in Melbourne. The project was specified by Docklands-based Elvin Tan Design Studio, showcasing the door system’s versatility and aesthetic appeal in a commercial setting. The sleek design and minimal storage requirement make it an excellent choice for modern retail and commercial environments.
Benefits of the Side-by-Side System
This innovative door system not only enhances security but also optimises space utilisation, making it a practical choice for businesses looking to maximise their operational efficiency without sacrificing style or functionality.
Australian Trellis Door Company (ATDC)’s premium grade security doors were recently installed for a prestigious project at Melbourne’s RMIT University, (project managed by Lendlease).


What Were We Tasked With?
The designers for the project, Lyons Architects, specified both ATDC’s S06 heavy duty concertina security door as
well as ATDC’s S04-1 DD Double Diamond Mesh portable security barrier to different parts of the same project.
The S06 concertina security door was specified and installed to numerous locations on this project including over the canteen area where it spanned a very wide 13 metre opening.
What Were the Challenges of this Project?
There was extremely restricted headroom due to numerous overhead services and the available daylight opening height was quite limited at 1200mm. In this application the S06 concertina security door was ideal for a number of reasons.
This door requires no headroom at all as it runs off a heavy duty extruded slimline aluminium top track (suspended by an overhead support beam). The S06 retracts and folds sideways to occupy just a negligible amount of storage room at only 15% of the overall span being secured.
This door can also be set out as a parallel (side by side) top track configuration which requires only an 8% storage factor. This is known as the S07-2 model door.
No Bottom Tracks Needed
By using a series of intermediate up/down locking mechanisms the client was able to achieve seamless lock up without the need for any bottom track (removeable or otherwise) to the counter top area and without the need for any cumbersome and unwieldy removeable mullions.

In a different location on this same project ATDC’s S04-1 DD deluxe grade Double Diamond mesh portable security barrier was specified and installed to the university’s rubbish bin storage and bin wash area.
In this instance, this trackless product was ideal since the existence of numerous services prevented any other type of structural door system from being installed. The barrier is portable and free standing, and accordingly was an ideal solution for the client.
The double diamond mesh meant a very robust barrier was supplied that could withstand the considerable impact and force it is subjected to in this bin storage area.
This door also offers folding and retracting sideways on to itself resulting in only a minimal storage space requirement. And with both floor and wall mounted locking options, an optimal security solution was provided.
Further, the pitch between the metal cross linkages on this door is only 65mm. This prevents anybody being able to gain a foothold and so deters persons from climbing over this door – one of its complying characteristics with the Australian Standards for Temporary Fencing and Hoarding.
For further information on ATDC’s double diamond barrier in other applications refer to this article.
ATDC’s heavy duty retractable security screens fold back sideways when unlocked and opened and are able to pivot 90 degrees away from the leaseline when in their stacked position.
The doors rotate in their stacked position at right angles to the opening on a carefully engineered self supporting steel frame which enables this pivoting action and thereby reducing the side storage stacking space to virtually nothing.
The pics show a recently completed installation of six (6) of these door systems for the NSW department of Education at Condell Park High School. Specified by ShakeUp Architecture and project managed by Sydney based, Neo-Way Pty Ltd.
