The Australian Trellis Door Company (ATDC) has solved a previously  problematic security issue for Australia’s leading shopping centre group and potentially for all other shopping centres (and similar high volume public entry points to buildings) across the nation.


A rise in the number of break and enters through the main entry doors into shopping centres in Australia has become a burning issue in recent times.This problem is further complicated by the fact that shopping centre entry doors normally fall within the restrictive deemed to satisfy provisions of the Building Code of Australia (BCA) and its emergency egress requirements.Hence the difficulty of providing effective security screening which does not fall foul of this quite onerous legislation.


Westfield Doncaster in Melbourne have recently successfully trialled the installation of ATDC’s expandable safety barriers within the airlocks at the entrance to its main entrance in an effort to deter further break-ins to its shopping centre.


The expandable safety barriers  installed at Doncaster comply with the BCA’s deemed to satisfy provisions in all relevant respects namely:


i)the barrier has a height not less than 1980mm;


ii)the barrier does not diminish the existing unobstructed egress width of exits and paths of travel to exits with in the shopping centre;


iii)the barrier can slide open as well as swing open;


iv)numerous provisions relating to doorways serving as a  required exit or forming part of a required exit are not applicable since the barrier is instead a door in a path of travel to a required exit


v)it is readily openable without a key from the inside by a single downward action on a lever positioned approximately 1m from the floor; and


vi)the handle is of a type that the hand of a person who cannot grip wont slip;and the handle has clearance from the back plate of between 35mm and 45mm
