The Australian Trellis Door Company ’s double diamond trellis door recently proved a great success in solving a sensitive security issue at Sydney's Marriott Hotel.
The hotel's high pressure water valves and water hydrants, which feed water into their fire sprinkler systems, required protection from public access. One of the problems, however, was that the valves were located in a narrow corridor, meaning conventional gates would not work due to insufficient space to hinge them.
A retractable concertina door, the double diamond door, solved this problem. By nature these doors fold sideways and occupy minimal side room, while the narrow gaps between the steel mesh in the doors prevent the public from putting their hands through to reach the water valves.
These double diamond trellis doors are also suitable in securing stock in businesses, such as bottles of alcohol in liquor stores, since it is very difficult to move the stock through the narrow gaps.
The double diamond trellis doors are constructed from steel, are galvanized against corrosion, and powder coated in a gloss enamel finish giving the doors a very modern and professional look.
