however, he maintains that they all
don’t perform the same.
“Pigmentation is used to make it
last longer,” he said giving an
example of the big yellow Makro
logo that sits outside all stores.
After his talk, attendees where
served lunch in the Palace’s lunch
area that included a large buffet
selection. Fully fed and ready for
more steel talk, Dennis White from
the Southern African Metal Cladding
and Roofing Association (SAMCRA)
was up next to discuss
metal cladding.
White went into the new roofing
codes stating that they require two
tables, one which is conventional
based on point and uniformly
distributed downward (UDC) loads
and the other table on wind load. He
further detailed special
environmental considerations
experienced throughout the country
explaining ponding as a big problem
and pollutants as the cause
of corrosion.
“Corrosion from pollutants is
more in winter than in summer,” he
said. Some of the reasons for steel to
corrode is when two surfaces are put
together, an overtight fastener,
wrong material, using nails or an
extreme connection. “The hotter it
gets, the quicker it corrodes. The
temperature of a roof in summer can
go up to 90°C, even with insulation
added it still gets hot,” he added.
After White’s presentation,
attendees enjoyed dinner and live
music, which gave them the
opportunity to mix with each other
in a chilled environment.
Many attendees found the
conference informative and relevant,
stating that White’s presentation was
practical, while Chavoos’ was
technical and interesting. Aubrey
Maleka from Cladco Projects said
that he’ll be taking what he’s learnt
back to the office to educate staff.
A total of 0.4 CPD points were
scooped up by those attending the
conference. Clint Africa, technical
marketing manager for Safal Steel,
said the conferences have
been rewarding.
