ATDC Involved in prestigious Wynyard Walk project in Sydney’s CBD

The Australian Trellis Door Company™ (ATDC™) has been involved with the NSW Government’s $300 million prestigious Wynyard Walk project in Sydney’s CBD, a project which entails construction of a world class, fully accessible pedestrian link connecting Wynyard Station to both Barrangaroo and the CBD western corridor.

ATDC was engaged by the lead architect for the project, Woods Bagot which approached ATDC to assist in designing a folding security door to secure Railway House, a heritage building on York Street with doorways leading on to York Lane.

Folding Security Doors

It was imperative that the folding security doors blended in to the surrounds of the historic building so as to have minimal impact and in this regard the doors were to be trackless and designed to pivot out of the way when unlocked and not in use. A special powdercoat finish (Signalschwarz) was selected from the international RAL powdercoat range to further complement the heritage façade of the building. For more information on ATDC’s pivoting trackless door view the product information here.

ATDC were involved in all aspects of the design process of the folding security doors and liaised with the project managers, CPB Contractors, to arrange for the challenging installation where ATDC were not permitted to affix to the heritage façade nor to lock on to it. To avoid attaching to the façade specially designed welded frames were constructed which were attached to the floor and ceiling. To avoid locking on to the façade special seamless up/down locking mechanisms were utilized. In addition the locking mechanisms on these folding security doors had to be keyed to the master key system used for the site.

Installations throughout Australia

ATDC’’s folding security doors have been installed on many heritage buildings throughout Australia including many of the old railway stations in QLD, NSW, WA and Vic. In each case the antiquated olde style appeal of these doors as well as their negligible impact on each of the relevant historic buildings have been their major advantages.

ATDC Completes Expanding Door Installation for Healthcare Facility in Sydney

The Australian Trellis Door Company™ (ATDC™) recently installed a Twenty (20) lineal metre curved expanding security door for a new healthcare facility at George Street, Sydney.

ATDC’s expanding security door features the latest cutting edge technology including seamless up/down locking mechanisms which are built into the door allowing for a secure closure without the need for any removable mullions. Once the door is unlocked and open it is completely out of sight and concealed within joinery cupboards at the extremity of the opening. (More information on ATDC’s S08 curved expanding security door here).

Heavy Duty Security Doors

The expanding security door is suspended from a heavy duty extruded top track which is shaped to accommodate exactly the tight curves and angles of the aperture –the top track is itself supported from a continuous top support beam which runs immediately above it without any air gaps. The top track is recessed into the ceiling and there is no floor track. Both factors enhance the seamless effect of the door. The tightest radius curve available is 600mm.

The expanding security door is also available on a parallel top track configuration whereby the door is designed to stack back in dual sections on multiple tracks thereby reducing the side stacking factor to a minimum. (More information on the parallel top tracking S07 side-by-side stacking door here)

With a maximum height of 4200mm, the expanding security door is fabricated from rigid square steel sections. It has a professional high quality powder coated finish. Standard colours are black satin or pearl white while other powder coat colours are available to suit almost any environment.

Suitable for securing curved apertures such as curved shopfronts, curved hallways and entrances, curved counter tops and hotel lobbies and reception areas, restaurants and kiosks.
