The GuardianWall is the ideal product for those clients seeking an industrial grade modular noise wall system that is far stronger and more durable than standard commercial grade solutions.

The modular wall system makes use of the hot dip galvanised steel beams that are typically employed for more rigorous construction applications by the building sector. This sets it apart from the lighter modular wall systems that are generally adopted in residential and commercial contexts.

The use of heavy-duty construction materials confers the GuardianWall with a level of durability far in excess of other modular walls. It has a +50 year design life, which means the owner can be reassured of its performance for at least half a century before the system will require maintenance inspections.

This enhanced durability makes the GuardianWall an excellent choice for large-scale industrial and civil infrastructure applications, where resilience and durability are deemed essential to long-term project performance.

In addition to its heightened strength and resilience, the GuardianWall can also be used in conjunction with a range of noise panels offered by ModularWalls, enabling developers to customise its performance to meet specific aesthetic and functional objectives.


  • Extra-tall wall heights
  • Ideal for extended design life requirements (+50 years)
  • Accepts multiple panel types
  • Customised components and finishes
  • Strong and durable
