About Our Treated / Tanalised Timber

We supply premium treated tanalised timber designed for outdoor construction and landscaping projects. This pressure-treated timber undergoes a specialised preservation process using copper-based preservatives, making it highly resistant to rot, fungal decay, and insect damage. Our tanalised timber range includes fence posts, rails, decking boards, and structural carcassing timber suitable for garden buildings, boundary fencing, pergolas, and external frameworks. The treatment process forces preservatives deep into the wood fibres, ensuring long-lasting protection even when used in ground contact applications. Browse our comprehensive selection online and benefit from competitive trade prices with reliable delivery across Greater Manchester.

Our Selection of Pressure-Treated Outdoor Timber

The tanalised treatment creates a distinctive green tinge that weathers naturally to a silver-grey finish over time. Our range encompasses various sizes from 47mm x 47mm fence posts to substantial 200mm x 50mm structural beams, all sourced from sustainably managed forests. This treated timber integrates seamlessly with other materials from our Timber department, offering builders and contractors a complete solution for outdoor projects. The copper-based preservative system provides Class 4 durability rating, suitable for structural use in ground contact and severe exposure conditions.

Professional landscapers particularly value tanalised timber for retaining walls, raised planters, and playground equipment where safety and longevity matter most. The treatment penetrates throughout the sapwood while maintaining the timber's natural strength characteristics. For interior applications requiring different specifications, consider our Sheet Materials or Sawn Timber Decking Scaffold Boards which complement outdoor structures with weather-resistant boarding and cladding options.
