The Australian Trellis Door Company™ offers a range of steel trellis doors as an economic solution for securing shop-fronts in shopping centres and on street-frontage.
These trellis doors are becoming increasingly popular in shopping centres as the main (only) store front door (no glass) due to their strength, through-visibility, competitive pricing point and low maintenance. These doors represent a significant cost saving for prospective tenants compared to the traditional forms of horizontal folding closures and vertical shutters. They are becoming increasingly preferred as the door of choice for closing off stores selling electronic equipment, white-goods and other high value items.
The company has recently developed a new egress-handle and protective plate solution to enable easy key-less opening and exit from the inside of the store in an emergency situation.
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 trellis door. A layer of 3M black vinyl film is applied to the Lexan to block out external visibility of the handle position (Lockwood lock and handle) situated on the inside of the plate/door.
Someone trapped on the inside of the store need merely push down the lever handle and slide the trellis door sideways to gain egress from the store.
For entry to the store, another lock (ATDC Three-point Alumax Lock) is fitted to the centre of the door for easy key-turn access. This lock may be keyed-alike to other restrictive locking systems.
