Lietzke Doors, Australia’s premier manufacturer of portable switchroom door units, was recently asked to provide door units for buildings heading to the South Hedland Power Station project, located in the north west of Western Australia. The Cyclone Rating for this location is Region D with the terrain rating Category 2 which indicated the doors needed to withstand the highest wind and impact rating on the Australian Mainland.

Lietzke already manufactures certified wind rated door units for this region but now has passed the impact tested option as well. The door units were tested at Azuma Testings NATA certified lab with an impact test speed of 44 metres per second. The door design passed with flying colours.

Lietzke is now in the manufacture and delivery phase of 31 specialised door units to Mayfield Industries, manufacturer of the switchroom buildings for the project.
