LIGHT GAUGE STEEL CONSTRUCTION

Light gauge steel construction is very similar to wood framed construction in principle - the wooden framing members are replaced with thin steel sections.

The steel used here is coated with zinc (called galvanized) or a mixture of zinc and aluminum (called zincalume or galvalume by some) to protect it from corrosion. The thickness of this coating can be varied to suit a range of environments.

The thicknesses of steel used here range from about 1 to 3mm for structural sections, and 1 to 2mm for non-structural sections.

Like in wooden framed construction, a frame of steel members is first constructed, and then clad with dry sheeting on both sides to form a load bearing wall. Construction with steel follows the platform frame system of house building. Connections between members are made with self tapping self drilling screws.

Contractors will usually order pre-punched sections - sections with factory-made holes in them - so that wires and plumbing can be easily passed through the walls. The gaps between members are filled with insulation.

This form of construction can also be used for non-structural framing, such as interior partitions or external cladding. In fact, this form of construction was originally developed for interior partitions in offices.

Advantages of light Gauge steel construction

Light gauge steel structures have many of the advantages:

  • They are light, and allow quick building without heavy tools or equipment. Every component can easily be carried by hand. The main tool is a light, handheld screw gun. Since steel is strong, Light Gauge Steel structures are lighter than wood framed structures.
  • Their higher strength allows greater spacing between members when   compared to wood frame construction: about 24" (600mm) for Light Gauge Steel structures vs. about 16" or 20" (400 or 500mm) for wood. Fewer members translates to quicker construction times.
  • It is able to shape itself to any form, and can be clad and insulated with a wide range of materials.
  • It is easy to change or modify this construction at any point in its lifespan.
  • There are a great range of systems and products catering to this type of construction.
  • Light gauge steel structures are non-combustible, which is a code requirement for some types of structures. Since steel loses its strength in fire quite easily, it must be protected from fire with fire rated sheeting.
  • Light gauge steel structures do not rot, shrink, warp, or decompose like wood structures, and can be used in areas where there is a probability of termite attack.
