Curved Security Door for Sydney Healthcare Facility by ATDC

New Technology
TDC’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.
Customisable For Your Needs
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.
Best Uses
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.
