Triple Track Bifold Shopfront Door

The Australian Trellis Door Company (ATDC) has pioneered a triple track commercial bifold door system which achieves  major storage space advantages for its customers.

At a  recent commercial fitout project  for Natalie Marie Jewellery at Avalon in Sydney,Annandale based interior architect X+O specified an S07-2 side-by-side parallel top track arrangement for ATDC’s commercial bifold door at the front of the retail store.The design intent was to minimize the side stacking depth of the door in order to provide maximum retail frontage for the client. For further product information and technical details refer to ATDC’s website at

Once on site,the project manager LJW Building was faced with even further door storage space limitations and required a maximum stack depth of 8% of the shopfront span.To achieve this ATDC installed its bifold door in a  triple top track configuration.The door stack achieved was just 450mm over a 5700mm shopfront opening span.An incredible achievement .And so vital  for retailers and other commercial businesses trying to squeeze every possible square metre of trading space with their expensive property rentals.

The triple track system offers seamless lock up with a series of intermittent up/down locking mechanisms and without the need for any floor track nor any removeable  mullions.The attached image shows clearly the set-up of this successful recent installation.

ATDC’s commercial bifold doors are now sold in Sydney,Melbourne,Perth,Brisbane,Canberra and Adelaide as well as in all regional centres across the country including Darwin,Townsville,Hobart,Geelong,Newcastle,Sunshine and Gold Coast regions.They are also being exported throughout South East Asia,The Asia Pacific,The PACIFIC Islands and the UAE.
