The benefits of light steel construction in relation to residential buildings are:

  • Speed of construction (up to 50% faster than traditional methods).
  • Excellent performance characteristics e.g. fire resistance, acoustic
    insulation, and thermal insulation.
  • High level of quality control, accuracy and freedom from shrinkage,
    reducing call-backs for defects.
  • Light weight for medium-rise and mixed use buildings, in which the
    residential floors can be supported on a podium level, thereby
    reducing foundation requirements.
  • Minimum disturbance to the locality during construction, with fewer
    deliveries; this is particularly advantageous where site constraints may
    limit the storage space available.
  • Waste recycling in manufacture and reduction of on-site waste.
  • Structural robustness and ability to create long spans and large

Rapid installation and early dry envelope allows other activities within the building to proceed much earlier than would be possible with block work


tall walls up-to 5m are readily achievable and with clear spans up-to 6.5m within the apartment non-loadbearing stud walls can adapt along with the future space requirements light guage steel walls can be used to support a wide range of cladding systems


The benefits of light steel framing and modular construction in housing are:

  • Speed of construction (up to 30% faster than traditional methods of
    house construction)
  • Excellent performance characteristics e.g. acoustic and thermal
  • High level of quality control, accuracy and freedom from shrinkage
    reducing call-back for defects.
  • Light weight for use on poor ground, with reduced foundation
  • Minimum disturbance to the locality during construction due to
    reduced number of deliveries.
  • Waste recycling in manufacture and reduction of on-site waste.
  • Compliance with Code for Sustainable Homes.
  • Room in the roof systems can be constructed without difficulty.
  • Can easily be extended and modified internally in the future.

The sustainability benefits of light steel framing and modular constructionare based on the off-site nature of the construction process; these are:

  • High levels of thermal insulation and air-tightness are achieved in light
    steel framing, and modular construction.
  • The light weight of these construction systems means that foundation
    loads and sizes are reduced by over 70% relative to concrete and
    block-work construction.
  • Productivity and speed of construction is increased by over 30% which
    reduces site impacts.
  • Transport is greatly reduced. A single delivery of light steel frames is
    typically sufficient for 3 houses.
  • Site safety is improved by a factor or 5 according to HSE statistics due
    to the off-site construction process.
  • Site waste is virtually eliminated by the use of pre-fabricated light
    steel and modular components compared to the industry average
    wastage of 10% in construction materials.
  • Use of components rolled to length results in no production waste.
  • Embodied carbon in the building fabric is reduced by up to 20% when
    using light steel framing and modular construction.
  • Renewable energy technologies can be attached to and built-in the
    light steel and modular components.
  • Light steel structures can be modified and extended easily. Modular
    units can be dis-assembled and re-used.
  • Light steel and modular construction are widely used in building
    extensions and in renovation, due to their light weight and speed of

High levels of accuracy, with no shrinking/creeping


The benefits of light steel construction in relation to fire safety are:

  • Steel is non-combustible; it does not add to the fire load of the
  • Fire protection for light steel framing is typically provided by the
    boards used for internal lining, e.g. gypsum-based boards.
  • Fire resistance periods of up to 120 minutes are readily achievable.
  • The amount of combustible material in a light steel framed building is
    much lower than in some other forms of construction.
  • Modules and pre-boarded light steel panels are fire protected before
    delivery to site.
  • Light steel floors, walls and modules are easily repairable after small
  • The fire risk during construction is much lower for light steel framing
    than for some forms of construction

The benefits of light steel construction in relation to durability are:

  • Maintenance-free, dimensionally stable
  • Design life predictions for light steel framing in a ‘warm frame’
    environment are in excess of 250 years.
  • The NHBC and other housing warrantee providers, require a
    design life in excess of 60 years, and accept the use of light
    steel construction.
  • Light steel sections are protected from corrosion by continuous
    hot-dip zinc coating.
  • Steel does not shrink, warp or change its shape.
  • Light steel construction can be used for walls, floors, roofs and
    suspended ground floors.
  • Steel does not creep under load.
  • Galvanised steel does not suffer from fungal or biological
    deterioration and is not susceptible to insect infestation.
  • Even in uninsulated roof constructions light steel sections
    provide a design life in excess of 100 years.

Reduces weight load and depth of foundations, increases design options

  • Light steel framing and modular construction provide robust
    structures that satisfy the Building Regulation requirement for
    avoidance of disproportionate collapse.
  • Robustness is provided by multiple members with a high degree
    of inter-connectivity.
  • Load bearing walls are produced that distribute loads rather
    than relying on discrete load bearing columns.
  • Light steel frame construction generally has lateral bracing
    distributed throughout the structure.
  • The form of construction creates multiple load paths which
    mean loads can be transferred around areas of local damage.
  • Light steel structures are capable of resisting high wind loads.
  • Light steel buildings are commonly used in seismic zones with a
    good record for surviving earthquakes and flooding.
  • The lightweight nature of the construction means that if any
    local damage does occur, debris loading is considerably less
    compared to heavier construction materials.
  • Steel is a ductile material which is able to sustain significant
    deformation without detrimental loss of strength.

Reducing follow on trade costs.


The benefits of light steel construction in relation to acoustic performance are:

  • High levels of acoustic performance can be achieved.
  • Light steel construction utilises multiple layers of construction,
    which are ideal for providing high levels of acoustic insulation.
  • Light steel products such as ‘acoustic’ studs and resilient bars
    are specifically designed to reduce sound transmission.
  • Junctions can easily be detailed to minimise flanking sound.
  • The high quality assurance ensures repeatable acoustic
  • There is a wide variety of proven light steel wall and floor
    construction systems.
