A new door locking mechanism from The Australian Trellis Door Company (ATDC) has been certified to comply with the Building Code of Australia (BCA) Clause D1 and D2 for doors, doorways and exits.

With this compliance, ATDC is now one of the few suppliers providing doors to comply with these regulations. Exit doors and their locking requirements receive special treatment under clause 2.21 of the BCA since they are an integral and vital part of the fire and safety infrastructure of any building.

The new egress handle and protective plate solution was developed by ATDC recently to enable easy keyless opening of the trellis door, allowing exit from the inside of a store in an emergency.

The plate is constructed from high-strength thick Lexan sheeting, which is cut, bent and slotted to enable it to slide with the concertina action of the folding trellis security door. A layer of 3M black vinyl film is applied to the Lexan to block out external visibility of the handle position situated on the inside of the plate/door.

Anyone trapped on the inside of the store needs to merely push down the lever handle and slide the trellis door sideways to gain egress from the store.

Entry is enabled by another lock, the ATDC three-point Alumax lock, which is fitted to the centre of the door for easy key-turn access. This lock may be keyed-alike to other restrictive locking systems.

The Australian Trellis Door Company is a specialist manufacturer of a wide range of steel trellis security doors designed to economically secure shopfronts in shopping centres and on street frontage.

The concertina security doors are increasingly being installed in shopping centres as the main and sometimes only, storefront door due to their strength, visibility, competitive pricing point and low maintenance. These security doors are also preferred as the door of choice for closing off stores selling electronic equipment, white-goods and other high value items.
