Pressure Treated Lumber for Durable Decking, Fencing and Outdoor Building Projects


Pressure treated lumber provides a practical material for decks, fences, landscape structures and other exterior projects. Lowe’s offers a variety of treatment types and wood options to support different outdoor applications while helping protect the material from decay and insect damage. Use the details below to compare options that fit your project needs.


Benefits of Treated Wood

  • Outdoor Project Versatility: Treated wood works across decking, fencing, garden structures, outdoor framing and other compatible exterior applications.
  • Decay Resistance: Preservative-treated wood helps protect lumber from fungal decay when used in applications suited to its treatment level.
  • Insect Resistance: Pressure-infused wood receives preservatives that help protect the material from damage caused by wood-destroying insects.
  • Structural Applications: Treated timber can be used for compatible posts, beams, joists, rails and other components in outdoor building projects.
  • Landscape Use: Chemically treated timber can support compatible landscape projects such as retaining structures, garden borders and other outdoor features.
  • Project Flexibility: PT lumber is available in different board types and profiles so materials can be matched to structural, surface or finishing applications.


Key Features of Preservative-Treated Wood

  • Treatment Categories: Above-ground options are designed for compatible applications where boards remain away from soil, while ground-contact pressure treated lumber is available for areas that require a treatment level suited to contact with the ground or greater moisture exposure.
  • Edge Profiles: Square-edge boards provide straight sides for framing and structural applications, while radius-edge pressure treated lumber features rounded edges that can suit decking and other visible outdoor surfaces.
  • Wood Construction: Pressure-infused wood retains the familiar appearance and workability of lumber while incorporating preservatives intended for appropriate exterior applications.
  • Finish Options: Paintable and stainable PT lumber options support different exterior finishing preferences after the material is ready for coating.
  • Application Options: Products are available for compatible uses including decking, fencing, landscaping and structural framing, making it easier to match the material to the planned project.
  • Finishing Compatibility: Treated wood can be incorporated into projects where painting, staining or sealing is planned after the material has dried according to product recommendations. 


How to Choose Treated Timber

  • Match the Exposure Level: Consider whether the lumber will remain above the ground or face regular contact with soil and moisture. Above-ground treated wood can suit compatible elevated applications, while other treatment categories are intended for more demanding exposure conditions.
  • Review the Intended Application: Select boards based on whether they will be used for decking, fencing, framing or landscaping so the material type aligns with the planned outdoor structure.
  • Consider the Board Profile: Choose square-edge material for applications that benefit from straight edges or radius-edge boards when a rounded profile better suits the finished surface.
  • Drying Options: Air-dried, green and kiln-dried pressure treated lumber provide different moisture conditions for compatible outdoor projects and finishing plans.
  • Confirm Fastener Compatibility: Choose fasteners and hardware intended for use with preservative-treated wood and suitable for the project’s exterior exposure conditions.


Pressure treated lumber supports outdoor projects such as deck framing, fence construction, landscape features and garden structures when the product type matches the planned application. Compatible deck screws, structural fasteners and exterior wood stains can support installation and finishing steps. Shop at Lowe’s.
