TAPERED LYSAGHT LONGLINE 305® IN COLORBOND® STEEL 0.70 BMT IN COLOUR SHALE GREY™
Located on the site of the existing Sydney Tropical Centre within the Royal Botanic Garden, Sydney, The Calyx is a new world-class attraction which features the largest living green wall in the southern hemisphere.
Designed as an extension of the Garden’s Arc Glasshouse, the $17 million exhibition centre replaced the former Tropical Centre pyramid and foyer and provides an integrated mix of indoor and outdoor areas to accommodate a variety of horticultural displays, regular hospitality events and cultural exhibitions.
On-site works commenced in late April 2015 and The Calyx was officially opened in June 2016 as a flagship bicentenary event to mark the Royal Botanic Garden’s 200th birthday.
With its circular form and strong, rib-like steel frame, the very nature of The Calyx made tapered LYSAGHT LONGLINE 305® cladding a natural choice for roofing the enclosed sections of the new exhibition centre.
With its own bold ribs rising dramatically from wide, flat pans and creating a strong visual where the tapered ends came together at the inner edge of the roof, tapered LYSAGHT LONGLINE 305® cladding perfectly complemented the striking circular structure.
The early engagement of Lysaght in the project, liaising closely with the architect to make certain their desired specification of tapered LYSAGHT LONGLINE 305® cladding would work in the design, was invaluable in ensuring their vision for The Calyx was fully brought to life.
This included carefully calculating the tapers required for each sheet of LYSAGHT LONGLINE 305® cladding and then scheduling the required manufacturing accordingly to ensure the sheets accurately followed the curvature of the roof.
Fixed in place with a specially designed, concealed-fix system, the tapered LYSAGHT LONGLINE 305® cladding delivered the flawless fanned deck envisaged by the architects.
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® cladding 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.
