ADVERTORIAL There’s no beating an original Over decades, ZINCALUME steel has become a household name within the building industry. When specifying premium high performance metallic coated roofing and cladding materials, this original and trusted brand remains the roofing material of choice for specifiers, says Arno Hanekom, the BlueScope Steel regional manager for Africa and the Indian Ocean Islands. Written by Gareth Griffiths for client, BlueScope Steel Southern Africa “ZINCALUME steel delivers strong thermal performance throughout its life. It’s also very easy to form and work with,” says Hanekom. “It stays brighter for longer. Due to its lightweight nature, it is an architect’s dream material for curves and shapes and can be formed into a variety of curved surfaces. A good example of this is the roof www.saroofing.co.za T Secunda Mall. over the departures terminal at Cape Town International Airport which is shaped like an aircraft wing.” The corrosion-resisting benefits of the product are considerable and a special AZ 200 (both sides coated with 200g/m 2 of Al-Zn coating) version is available for use within the 5km distance of the sea or in areas where there is a strong industrial fallout. ZINCALUME’s lifespan is reported as four times longer than conventional galvanized steel. “Hence a special corporate warranty of performance applies when product is fitted in an approved way,” adds Hanekom. ZINCALUME has been used extensively throughout South Africa. Clotan Steel expertly formed ZINCALUME into its Craft Lock profile for use at the Secunda Mall as specified by architectural firm, LP Architects. The double- storey mall was completed in late 2013. “If the good name of your practice is on the line, why risk your reputation by using generic Al/Zn coated steel when you can enjoy peace of mind by using genuine ZINCALUME steel?” asks Hanekom. he product’s 55% Al-Zn technology is licensed internationally by BIEC International Inc, a BlueScope subsidiary. In the mid-2000s, the acrylic surface resin applied to coils of the product at the factory was upgraded, yielding significant advances in performance and formability. The choice of roofing material influences the amount of solar energy that enters a building, affecting climate control and building comfort. To mitigate against heat, ZINCALUME steel has an attractive, shiny appearance designed to limit solar absorptance. All roofing products are subject to weathering however, BlueScope’s product will stay brighter for much longer than alternatives, providing about twice the thermal performance of other commonly used materials such as weathered (12 months plus in a natural environment) galvanized steel and fibre cement / asbestos.
