ADVERTORIAL: COVER STORY
The ultra-steel solution
Determined on using highly engineered roofing systems,
MiTek and Rooftek joined forces to elevate steel roof
design at Mediclinic Stellenbosch.

Ultra-Span light gauge steel was used for the project.
P
rovider of software solutions and
suppliers of roof truss products,
MiTek Industries South Africa and
top truss manufacturer Rooftek
innovatively collaborated on a major steel
roofing project for Mediclinic Stellenbosch,
situated on the banks of the Eerste River in
the scenic town of Stellenbosch in the
Western Cape.
For the roof design, the team made use
of an Ultra-Span light gauge steel structure.
Backed by a professional engineering and
estimating department, Ultra-Span is a
pre-fabricated light gauge steel roof truss
system that is both lightweight and compact
for economical transportation costs.
Spanning a total area of 4 500m², the
Ultra-Span light gauge steel roof consists of
a hipped structure with Dutch gable ends.

With truss spans ranging between 14m
and 20m, the inverted shape of the Ultra-
Span roof trusses opened a new door for
design requirements of light steel frame
roof structures.
Drawing the attention of architects and
engineers, the special shaped inverted
Ultra-Span roof trusses provided a
structurally sound roof structure that was
designed to accommodate services like
HVAC units and ducting as well as solar PV
panels to the one elevation of the roof
structure. This has opened up an
opportunity for Ultra-Span in the Western
Cape, especially in the field where non-
combustible material must be used.
The roof structure was detailed to be
supported in-between the concrete ring
beams on brackets. This created design,
cost and erecting challenges, given
the timeframe to erect the required
roof structure.
Engineering excellence
Engineered designs are calculated using
MiTek’s state-of-the-art, in-house
developed 20/20 software and provides
economical roofing solutions. The low mass
per square metre of this roofing system
ensures both savings on the supporting
structure as well as on transportation and
erection costs whilst also being vermin
proof and non-combustible.
MiTek Engineering Cape Town designer
Jaco van Wyk came up with the required
framing solution for the project which is
more cost effective in a variety of fields
throughout the project. “The erecting of the
