Melbourne’s Penleigh and Essendon Grammar School’s Infinity Centre is secured by four-metre-high curving retractable trellis security doors.

The Infinity Centre addition to Penleigh and Essendon Grammar School, profiled here, was constructed in 2011 and features the visual motif of the infinity symbol, or lemniscate, in reference to “infinite knowledge.”

Securing the unusually shaped entrances, which are very wide curved apertures with pronounced sloping floors and an absense of walls to lock the security doors to, required the use of the Australian Trellis Door Company’s (ATDC) curved trellis security doors. ATDC were specified for the project by architectural firm McBride Charles Ryan, which worked closely with ATDC in detailing all aspects of the security door installation for the project. 

ATDC’s retractable steel security doors were installed over school entries, hallways, passageways, alcoves, doors, windows, classrooms, playground access areas, school hall, library and service desk areas.

The doors are eminently suitable for securing many institutional buildings, like technical and trade colleges, universities, schools, kindergartens, daycare centres, government buildings, museums, exhibition centres and art galleries.
