The Australian Trellis Door Company (ATDC) recently installed its innovative S07-2 dual track concertina doors at a fresh food retail store in Richmond Quarter near Melbourne.

Specified by Docklands-based ElvinTan Design, ATDC installed three of these large concertina door systems for De Marias Grocer to a height of 3600mm each on a dual top track mechanism. The concertina doors were designed to reduce the overall storage stack space to only 10% of the opening spans when unlocked and folded back; the widest of these apertures is approximately 13.5 metres in width.

Project managed by Dandenong-based Sabrina Shopfitting, ATDC used a system of multiple intermediate up/down locking systems so that the installation could achieve a seamless lock up, thereby eliminating the need for any floor track.

With the open style grille mesh infill on these doors, the fresh food retailer has maximum ventilation through the metal cross links.
