The Australian Trellis Door Company (ATDC) ‘s versatile security doors are an ideal method of securing the often difficult contours of angled bench tops, counter tops, serveries and reception areas.
ATDC recently installed its curved steel security door to suit the hexagonal shaped bar counter at the Skyring Terrace’s Haven Kiosk at Newstead in QLD.
Architecturally specified by TwoHill & James of Fortitude Valley, QLD, this unique folding security door was configured in a curved format with four off 600mm corner radius curves.
The door was designed without the use of any floor track and is instead secured by a series of intermediate up/down locks and commercial grade patio bolts to facilitate seamless lock up without the need for any cumbersome removable mullions. A professional high gloss pearl white powder coat finish was applied to the door for this project.
Project managers for the job were Lamberts of Coopers Plains.

ATDC Trellis Doors
ATDC’s S04 trackless expanding security doors were installed to the bar areas on two different levels of the building. When unlocked and opened these doors fold and stack back to a minimal storage size of just 12% of the opening width being secured thus making them an attractive option to specifying architects and developers alike.
