Why Steel Frame?

  • Highest strength-to-weight-ratio
  • 100% recyclable
  • Non-combustible – does not burn and will not fuel a fire
  • Dimensionally stable – does not expand or contract when exposed to moisture
  • Consistent material quality – produced according to strict manufacturers standard

Quality

  • Complies with the National Build Code SANS 517 and Rational Design.
  • Tried and tested – has been in use in Australia, Europe & America for decades
  • Each structure is signed off by a structural engineer
  • Only quality certified material is used
  • Frames are assembled under controlled factory conditions
  • In the case of poor foundation conditions, steel framed buildings can
  • accommodate some movement in foundations without cracking
  • Thermal insulation can be specified to be superior to conventional buildings
  • Professional finishes are readily available
  • SASFA, the industry association, will act as a quality watchdog, and system component frame erectors and builders will be accredited

Cost Efficiency

  • Speed: time saving is estimated to be more than 30%, compared to conventional
  • building
  • Accuracy: a steel frame dictates a high degree of accuracy of building dimensions
  • Light weight: a steel framed wall clad with fibre cement/plaster board offers a mass
  • saving of 90% compared with a double skin brick wall
  • Sloping sites: the building method lends itself to column foundations and
  • suspended floors, reducing the cost of building on uneven sites
  • Minimal wastage
  • Energy efficient
  • Flexibility: horizontal and vertical additions can be effected easily, in stages
  • Extra floor space (some 4% due to reduced thickness of external walls compared
  • to double skin brick walls
  • Services are installed in wall cavities without chasing of the walls
  • Accurate cost budgets

Benefits to the End User

  • High strength results in safer structures, less maintenance & slow ageing
  • Fire safe
  • No cracking plaster
  • Excellent thermal properties
  • Not vulnerable to termites
  • Mould free houses
  • No toxic chemicals are used to treat the steel, unlike timber
  • Not vulnerable to fungi or organisms
  • Less chance of foundations problems as it is 3x lighter than wood, resulting in less
  • movement
  • Less probability of damage due to earthquake or high winds due to lighter structures, stronger connections, screws versus nails

Benefits to the Builder

  • Lighter than other framing materials – no lifting equipment needed on site
  • One person can carry a 5 meter fabricated panel
  • Straight walls and square corners
  • Call backs due to cracks are eliminated
  • Windows and doors open as they should
  • Less scrap and waste (2% for steel versus 20% for wood)
  • No drying out period in wet weather, no delays
  • Cost effective
