The Australian Trellis Door Company (ATDC) has installed an expandable t-max aluminium security door to each of the two large entries to this world leading surf park facility, which has recently opened at Sydney Olympic Park.

Product design specifications

Each expandable gate installed on the project is 5500mm wide x 3400mm high and constructed from rigid aluminium sections in order to combat the corrosive marine environment of the surf park facility. By utilising recessed floor tracks, there is no impediment to the free flow of pedestrian traffic through the entry gates to the surf park. Locking is achieved through a 3-way locking mechanism, which can be keyed to the building’s master key system. The specified finish was Monument powdercoat from the Dulux Duralloy range.

Project work

The specifying architect was Surry Hills based Clarke Hopkins Clarke and the job was project managed by North Sydney based construction firm Lipman Pty Ltd.


A 12-month warranty on materials and labour is provided on this product by ATDC.
