The Case for Light Gauge Steel: MATERIAL EFFICIENCY - Timber vs. Steel

 

HOWICK - THE Material efficiency OF LIGHT GAUGE STEEL

THE ENVIRONMENTAL IMPACTS OF USING STEEL ARE SIGNIFICANTLY LOWER THAN USING TIMBER IN CONSTRUCTION

 ...using light gauge steel roll forming technology from Howick FRAMA machines...

 

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 1 cubic metre of steel vs. 1 cubic metre of timber - when used in the construction of a simple two storey 200m2 house with a 2.4m stud - shows the following compelling contrasts:

1 Cubic Metre of Timber
4 x 2 stud timber
Metres of wall at 2.4m stud = 30.06m
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 = 0.75mm
Metres of wall at 2.4m stud = 809.5m
Total number of houses produced = 3.33 [21 x MORE THAN TIMBER]

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