Also called pressure-treated timber, treated timber is wood that has been treated with chemicals to protect it from pests, decay, water damage and other environmental factors such as frost. Tanalised timber has usually been treated with chemicals that contain copper, which is designed to penetrate deep into the wood and provide long-lasting timber

At Beesley & Fildes, we sell FSC® and PEFC™-certified tanalised timber products that have been treated with copper triazole technology to produce a variety of finishes that will suit a wide range of building projects. 


How is timber treated?

Timber is typically treated through pressure treatment. In this process, the timber is placed in a large pressure vessel where it is first vacuumed to remove any air from the wood cells. Once the air has been removed, the vessel is filled with a solution of chemicals that are designed to protect the pressure-treated timber from decay, insects, and other types of damage.

Can treated timber get wet?

Yes, treated timber can get wet. In fact, it is common for pressure-treated timber to be exposed to moisture in outdoor settings with projects such as decks, fences, and retaining walls. However, treated timber is treated with chemicals that protect it against damp/moisture and other environmental factors that can cause wood to deteriorate quickly.

How long does treated timber last?

The lifespan of treated timber depends on a variety of factors, including the type of treatment used, the quality of the timber, the conditions in which it is used, and the level of maintenance it receives over time.

In general, treated timber can last for decades, with some estimates suggesting that it can last up to 40 years or more.

Is pressure-treated timber safe?

Pressure-treated wood can be safe to use, as long as it is handled and installed properly.

What is tanalised treated timber?

Tanalised treated timber is a type of timber that has been treated with a solution of chemicals to protect it from decay and insect damage. The process of tanalising involves immersing the timber in a tank of a preservative solution under high pressure, which forces the solution deep into the wood cells to treat it from the inside out.

What are the main benefits of pressure-treated wood?

Treated timber has several advantages over untreated wood. Because it is protected against decay and insect damage, it has a longer lifespan than untreated wood and requires less maintenance over time. Pressure-treated wood is also less likely to warp, split, or crack, making it a more stable material for use in construction and landscaping projects.
