Light steel frame construction techniques to create structurally
sound dwellings in South Africa is one of the most exciting developments
to hit our shores in recent times even though this method of building
has been used in the UK, US, Europe, Australia, and New Zealand
for decades.
It offers quality, cost efficiency and speed of erection for
low-rise residential and non-residential buildings.
The key to the success and rapid growth of light steel frame
construction worldwide lies in a seamless interface between computer-based
design and computer-controlled manufacturing. Sophisticated design
programs have been developed to carry out the structural design
of each element required for a building and to electronically convey
the dimensional specifications to the roll-forming facility.
There are several advantages of light steel frame construction
compared with conventional building in terms of quality, cost, durability
and speed.
Light steel-frame building consists of structural wall frames
and roofing systems manufactured from cold-formed galvanized or
ZincAlum structural steel sections ranging from .55 mm to 1.2 mm.
Various interior and exterior cladding options ensure that almost
any style of building can be achieved.

Electrical and plumbing considerations are essentially encompassed
within the framework of the cladding.
Light steel frame building offers a wide range of benefits when
compared with conventional building or other framing materials,
in terms of quality, cost, durability and speed.
Reduced wastage, lower logistical costs and reduced time of construction
could offer cost savings of 15% or more, compared with conventional
building.
Steel framing has many advantages over conventional brick and
timber structures. A completed house using an internal steel frame,
typically clad with exposed face brick or painted plastered finishes,
is virtually indistinguishable from homes built using conventional
South African techniques.
It is also estimated that steel framing saves substantially on
building costs, mainly owing to reducing construction duration and
eliminating a large portion of inefficient site labour. The client
saves owing to reduced damage clean-up cost, holding charges and
ongoing mortgage costs.
Quality is another aspect that differentiates steel framing from
conventional building methods. Steel frames are produced only from
computer-aided design (Cad) software, which ensures that all elements
of the home conform to the designer’s plans and also allows
optimum design freedom.
Steel does not sag or rot over time and represents a significant
improvement in quality over existing timber roof-framing systems.
In addition, steel framing also has some environmental benefits.
Steel is a reusable resource and steel frames can be erected
in environmentally sensitive areas with minimal impact. It is interesting
to point out that lightweight steel-framing systems offer similar
environmental performance over the life of the product to that of
conventional double-brick construction techniques.
