Designed for reliability

The internal structural frame is manufactured from 2mm sheet steel. Walls, roofing and doors are manufactured from 2mm sheet steel. Marine-grade aluminium or stainless steel is also available as an option.


The switchroom base frame is supported by its longitudinal PFC external members, with UB cross members and floor joists spaced and welded to exceed minimum engineering standards and prevent flexing.


The standard switchroom building floor is non-combustible, with a surface finish of 2mm heavy duty vinyl tile. A two hour fire rated floor is available as an option.

Gland plates

To allow suitable entry for power and control cabling into the switchroom and switchgear, gland plate entry systems are utilised. Gland plate systems also provide dust and water ingress protection. Bolted coupler bulkheads are available to support mining and heavy industry plug and cable systems. A fire rated cable entry system can also be supplied.

External Walls and Roof

External linings of the walls and the roof are finished with pre-painted Colorbond Steel (other options available). Our standard profile is Superdek roofing at the required pitch.

  • Roof sheets are dressed at the ends
  • Anticon insulation is installed under cladding (wall and roof)
  • Superdek cladding colour to client’s specification
