Why Light Gauge Steel - Material Efficiency

Timber vs. Steel

Light gauge steel from Howick FRAMA machines is a considerably more efficient building material for housing and has significantly lower environmental impacts than using timber in construction

Some argue that steel is a less environmentally friendly construction material than timber due to the relative amount of energy it takes to manufacture. However, there is evidence proving that steel is a considerably more efficient building material for housing than timber.

A direct comparison of the material efficiency of one cubic metre of steel vs. one cubic metre of timber - when used in the construction of a simple two-storey 200 square metre house with a 2.4-metre stud - shows the following compelling contrasts:

 

1 Cubic Metre of Timber
4 x 2 stud timber
Metres of wall at 2.4-metre stud = 30.06 metres
Total number of houses produced = 0.124

 

NOTE:

  • Special timber for trusses and floors (different from wall timber) is required.
  • Timber framing is twice the weight of steel framing so onward transportation requires more fuel.
  • Timber waste is typically 20%.

 

1 Cubic Metre of Steel
Thickness = 0.75 millimetres
Metres of wall at 2.4-metre stud = 809.5 metres
Total number of houses produced = 3.33 (21 x MORE THAN TIMBER)

 

NOTE:

  • The same steel used for the walls can also be used for trusses and floors.
  • Steel waste is typically 2-3%.
  • Steel is up to 99% recyclable.
