The Applied Science Building at the University of NSW is a landmark in the Eastern Suburbs of Sydney.
This world-class multi-storey complex of research laboratories and lecture theatres has recently been extended and upgraded, including the air conditioning and fume extraction systems.
The new air conditioning and ventilation systems were placed on the roof. Management at the University were concerned that the upgrade would be a major disruption and not one they wished to endure more than once in a generation. They needed materials to be long- lasting and require minimal maintenance.
As contractors on the project, Croydon Industries chose a new generation marine grade stainless steel. 445M2 was selected for the ducts on the roof, which are exposed to a marine atmosphere created by surf at Maroubra Beach just a few kilometres away.
Brian Clark at Croydon Industries says, “This was the first time we used 445M2, and we were a bit apprehensive - but it gave us no problems. It formed very easily, producing clean lines and well shaped panels with no flaws.
“The stream diffuser sheet of perforated metal was a dream to make. “The punching ran cool, the sheet came out flat, with very little burr and at a lower cost than the familiar 316. We’re glad we opted to use 445M2, it’s been a win-win for all.”
