Australian Trellis Door Company™’s (ATDC™) unique security door is ideal for retailers of valuable merchandise which by their very nature require particularly strict protection and control, namely firearms, alcohol, cigarettes and pharmaceuticals.

Efficient Security Doors

ATDC’s security door is robust and strong being constructed from heavy duty steel; it is fully framed if required which enhances impact absorption and also has multi-point locking options.

ATDC’s security door can be configured  to form a functionally strong and decorative security cage (as depicted in the attached photograph) allowing the retailer to both protect merchandise whilst at the same time clearly displaying the goods for customers to see. With only limited numbers of employees receiving keys to the security cage inventory control is further enhanced.

Being fully retractable, this versatile and space efficient security door folds back to only 15% of its expanded size allowing the retailer to quickly access the products when needed. For more information on this unique security door please visit our website

Further this security door is also available in a double diamond configuration where the lattice is tightly interwoven resulting in a 65mm pitch between the metal cross links and so preventing persons from being able to reach through the security door to reach the valuable items behind it.

Concertina Retractable Screen now with Retractable Insect Screen

The Australian Trellis Door Co (ATDC™) has recently successfully adapted a retractable flyscreen to its concertina style security screens.

Innovative New Ideas

It has been a perennial challenge for ATDC’s engineers, trying to successfully adapt flyscreen mesh to collapsible style security screens due to the potential of the insect screen mesh becoming intertwined amongst all the moving parts of the security screens.  ATDC has overcome these issues by utilizing a high quality spring loaded flyscreen which retracts in tandem with the security screens and slides along a fully captive extruded aluminium top and bottom track, rolling into a concealed slimline pelmet box on the side of the opening. These insect screens are similar in colour to the security screens and so are almost invisible and unnoticeable, blending into the surrounds.

This innovative idea meets a growing customer demand for ATDC’s security screens namely to provide formidable security screens whilst also providing protection from insects and other vermin.

Domestic Security Doors

Typical domestic applications for ATDC’s security screens including securing sliding glass doors, patio doors, alcoves, carports, French doors, windows, passageways, front doors and bi fold glass doors.

Unique to ATDC’s security screens is that whilst providing a formidable security barrier, they fold out of sight when not in use behind curtains or blinds so as to be practically invisible.

When locked, ATDC’s security screens permit maximum sunlight to filter into the room they are securing allowing the free flow of fresh air and ventilation, keeping the room light, fresh, bright and breezy and now also preventing flies and other insects from entering the premises through the screen.

Precision engineered from marine grade aluminium or toughened steel ,ATDC’s extensive range of security screens have multi point locking options, full frames for extra strength and either stainless steel rivets or brass rivets providing that extra level of home security.

Our Service Areas

ATDC’s extensive range of security screens are now sold in Sydney, Melbourne, Brisbane, Adelaide, Perth, Canberra, Newcastle, Geelong, Townsville and in all other regional towns and centres across Australia.

Australian Trellis Door Co (ATDC™) has recently installed its FC1 bifold doors closures at the new WH Smith store at Sydney International Airport.

WH Smith is a British based global retailer of books, stationery, newspapers, magazines and entertainment products and employs over 14 thousand staff in over 1400 locations around the globe.

Quality Security Grilles & Closures

ATDC’s bi-fold doors were ideal in this application given the massive size of WH Smith’s storefront (totalling nearly 53 lineal metres) with its irregular curved shapes, sloping floors and the requirement for ventilation which in this case was provided by the perforated metal finish of the screen which permitted maximum airflow. Lexan, Polycarbonate, aluminium or even tempered glass are other optional finishes.

ATDC’s bi-fold doors have the added advantaged that they can span these large apertures without the need for both cumbersome removable mullions and costly motorization options. Further, the folding doors can accommodate difficult potential obstructions such as multi-level counters and counter cut-outs. And the further option of having emergency egress doors within the folding door allows for BCA compliance where necessary.

ATDC’s folding doors can be installed as either internal bi-fold doors or even external bifold doors to commercial premises as required according to each application making them extremely versatile. These folding doors are available in a natural anodised finish or they can be custom powdercoated and colour coordinated to blend in with almost any colour scheme.
