A new door locking mechanism developed by 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. ATDC is now one of the few suppliers of 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.
ATDC’s new egress handle and protective plate solution enables easy keyless opening and exit from the inside of the store in an emergency situation. Constructed from high-strength thick Lexan sheeting, the plate 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.
Someone trapped on the inside of the store needs to merely push down the lever handle and slide the trellis door sideways to gain egress. Another lock, the ATDC three-point Alumax lock is fitted to the centre of the door for easy key-turn access to enter the store. This lock may be keyed-alike to other restrictive locking systems.
ATDC offers a range of steel trellis security doors designed as an affordable solution for securing shopfronts in shopping centres and on street frontage. These concertina security doors are becoming popular in shopping centres as the main and sometimes only, storefront door due to their strength, visibility, competitive pricing point and low maintenance.
Representing significant cost savings for prospective tenants, these security doors are increasingly being preferred for closing off stores selling electronic equipment, white goods and other high value items.
