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.

“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

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.
