During a severe cyclonic event, cyclic forces can induce fatigue in roofing materials, their supports and fixings; fatigue which often limits the performance of a component or system. These forces must be considered when designing or selecting cladding materials, their fasteners and supports.
To assist in the design and installation of buildings using LYSAGHT® roofing and walling materials, refer to the Cyclonic Area Design Manual downloadable below. This newly released manual details results of extensive testing recently conducted in BlueScope Lysaght’s NATA accredited testing laboratory, using the direct pressure testing rig which offers the full benefits of the latest methods for modelling wind pressure. Testing was conducted in accordance with the new low-high-low requirements of the revised Building Code of Australia (2006).
Please be aware that in some Australian states cladding must be installed by licensed tradespeople.Download LYSAGHT® Cyclonic Area Design Manual Steel Roofing & Walling (463 KB)
