Treated timber is primarily used for outdoor applications where it's exposed to the elements, such as:

  • Decking: Creating outdoor decks and patios.
  • Fencing: Constructing fences and gates.
  • Outdoor structures: Building sheds, pergolas, and garden structures.
  • Exterior cladding: Covering the exterior walls of buildings.

The treatment process, often involving pressure-treating with chemicals, helps to protect the wood from rot, decay, and insect infestation, ensuring its longevity in harsh outdoor conditions.
