Treated Timber For External Use

In addition to our UC4 standard-treated posts, Crestala also stocks treated sawn Framing and CLS-style timber treated to UC3 for general external use above ground. This includes shed building, decking support frames, landscaping, and garden work. Sizes range from 50mm x 25mm (2" x 1"), up to 195mm x 47mm (8" x 2") in lengths ranging from 1.8m (6 feet) up to 4.8m (16 feet). All are ready for collection or delivery.

All of our wood is treated to the appropriate level to provide the best possible lifespan for its intended use. The exception to this is that Chestnut and Oak products are untreated. Please read our guide on the Safe use of treated timber.
