Queensland Alumina Limited

Gladstone, Queensland, Australia

Queensland Alumina Limited (QAL) was Australia’s first alumina refinery and remains one of the largest in the country. Covering an 80 hectare site on the outskirts of Gladstone, the refinery produces around 3.8Mtpa of high grade product. The bauxite that is processed to make alumina is mined in far north Queensland and shipped 2,000km to Gladstone. Alumina is produced through the continuous four state ‘Bayer’ process.

Walz Group has a longstanding relationship with QAL and we are proud to be a trusted provider of scheduled maintenance and shutdown projects, as well as ongoing sustainability works. We also provide scaffolding services for shutdown works through our specialist plant and equipment. Walz also supports the refinery through our light, medium and heavy and piping fabrication facilities and protective coating services. Our constant presence on site supports the smooth operation of the refinery through a range of ongoing works. We also perform occasional major capital works.

Over the past five years we have carried out more than 390 projects at QAL, valued in excess of $46M. The works ranged from minor sustainability such as handrail replacements, to major capital works projects like replacing a conveyor.

Some of our key projects at QAL include:

  • Caustic Tank Floor Replacement (T15Q005 + T1515)
  • Major evaporation turnaround works
  • Power steam header remediation and upgrade works
  • Conveyor replacements
  • Miscellaneous structural, mechanical and piping works as required
  • Miscellaneous shutdown works as required
  • Providing scaffolding services for all shutdown works
