OVER 7 KILOMETRES OF TAPERED LYSAGHT LONGLINE 305® STEEL ROOFING
JIT DELIVERY OF OVERSIZE SHEETS VIA LONG-LOAD TRAILER FROM SYDNEY
0.7MM COLORBOND® STEEL IN THE COLOUR WALLABY™
The $9.8 million development of the Riverside Precinct at St Mary’s College Ipswich was part of an overall redevelopment of the college grounds and facilities and followed the earlier restoration of Mercy House convent.
Established in 1863 by the Catholic Sisters of Mercy, the college is part of the Ipswich Heritage Trail and the convent a prominent landmark and important icon for the local community.
The new Riverside Precinct replaced a string of demountable buildings that were previously situated on the college’s “prime real estate” on a rise overlooking the Bremer River.
The project involved a number of inter-connecting buildings exhibiting a curvelinear shape to follow the contours of the site while maintaining views to and from the convent.
The finished buildings house 17 teaching spaces including Art, Science, Home Economics, Hospitality and Music, Dance, Drama.
The curving design of the buildings’ roof area presented an ideal opportunity to showcase the unique tapering capability of LYSAGHT LONGLINE 305® cladding.
With its wide, flat pans and bold vertical ribs, LYSAGHT LONGLINE 305® cladding provides a strong, linear visual statement to the roof line of these building.
Utilising tapered sheets of the long length, concealed fix decking enabled the contractor to achieve a continuous watertight finish which embraced the unique curving design of the structure.
Long length 16 metre sheets of LYSAGHT LONGLINE 305® steel were manufactured at the Lysaght Emu Plains facility in western Sydney and road freighted to Ipswich on special long-load trailers. Consecutive sheets were manufactured, bundled and delivered to site on a JIT basis to minimise site congestion and maximise on-site efficiencies.
The complex ‘Double S’ curve design potentially presented significant issues with alignment of the individually tapered sheets to ensure that each sheets was perfectly installed in its correct position. To assist the roofing contractor, Lysaght developed an innovative ‘laying grid’ that showed the exact location of where every individual sheet needed to be.
LYSAGHT LONGLINE 305® STEEL CLADDING
This distinctive profile adds visual interest to large areas by casting evolving shadows which change the look of the roof throughout daylight hours.
For even greater design freedom and aesthetic interest, LYSAGHT LONGLINE 305® can also be fluted and tapered to create strong lines radiating out from a central design point across the expanse of the roofing structure.
The product is manufactured from 0.7mm ZINCALUME® steel or COLORBOND® steel and has a standard cover width of 305mm.
Strong and durable, the water carrying properties of concealed-fixed LYSAGHT LONGLINE 305® cladding makes it suitable for roofing applications with a pitch as low as one degree.
The specially designed concealed-fix system allows for thermal expansion and the absence of screw penetrations eliminates the potential for water ingress over time.
