Our Treated Timber Products

Vuka Timbers is a South African treated timber supplier. Our eucalyptus wood is treated with either creosote or CCA and meets the ACT stamp of approval. Our treated timber is used for a number of different applications. The main categories of treated timber uses are electric transmission poles, telecommunication poles, wooden poles for agriculture and construction.

However, treated timber may also be used for DIY projects, for example. Timber sizes and prices depend largely on your required uses. Rather than listing all timber sizes and prices on this page, we have described our wood and treated timber types. To get a quote for your specific treated timber requirements, please contact us.


We Use Eucalyptus Wood

All our poles are made from eucalyptus wood.
Eucalyptus trees (scientific name Eucalyptus Grandis) are tall, self-pruning trees with a smooth bark. One hectare of land may support over 1600 eucalyptus trees. A mature eucalyptus tree may reach a height of more than 30m, making it ideal for producing long poles. The trees are harvested once they have reached maturity.
All our timber is sourced from sustainable plantations. We know that forestry is a long-term business, and have adopted the same long-term view for our future. This enables us to source the correct timber, at the correct time, to ensure we are able to meet our customers’ needs within reasonable lead-times.
We are also able to monitor rotations, growth and quality of the timber while it grows, making sure we deliver only the best poles to you, our customer.

All Our Timber is Treated

We use pressure-treatment methods to treat our wood. Our processes utilize the latest technology to ensure optimal and cost effective operations to offer you the best timber prices.

Creosote-treated Timber

Creosote is a wood preservative that protects wood from a wide range of biological and environmental agents. This chemical is toxic to fungi, insects such as termites and marine borers. Additionally, it serves as a natural water repellent.

Creosote is ideally used in the preservation of telephone poles, transmission poles and fencing poles. The chemical leaves the timber pole dark brown to black.

CCA-treated Timber

CCA stands for copper, chrome, arsenic. CCA treatment contains these elements in various proportions. We use this treatment to protect wood from micro-organisms and insects. Like other copper-based wood preservatives, it gives the timber a greenish tint once treated.

The science of treating timber properly provides for the preservative to be deeply impregnated into the sapwood, thereby giving a deep envelope of treatment around the central heartwood.

It is preferable that you purchase your treated timber in the size in which you intend to use it. If this is not the case and you subsequently cut the timber, you may expose the untreated heartwood of the timber and compromise the integrity of the treatment. If you plant timber, e.g. a treated post, in the ground, it is also essential that you allow for drainage of rainwater through the timber.

The ACT certification system is a testing entity that ensures that wooden products in South Africa comply with legal strength and quality specifications. All our treated timber products have the ACT stamp of approval.

Timber Sizes and Prices

Since all timber is pre-cut to your specific size requirements before treatment, standard timber sizes and prices are often not applicable to our clients. To obtain a quote for your specific timber requirements, please contact us! 

Vuka Quality Control

Our wood undergoes a number of different quality checks before receiving the ACT stamp of approval. This includes allocating the correct hazard classification to the wood.

Hazard (H) Classification:

Choosing the correct (H) class for your application. Each wooden pole has a marker at the end which indicates the Hazard Class Symbol of the treated timber. This Hazard Class Symbol indicates the hazard level for which the wooden pole has been ideally treated. For this reason, we ensure that wood with different end use applications receives different treatment levels.

Here is a summary of the different Hazard Classes:

Hazard Class Symbol: H6

Hazard level: High/Marine

Suitable for: prolonged immersion in sea water.  Consequently, this timber is ideal for marine piling, landing steps, retaining walls, etc.

Hazard Class Symbol: H5

Hazard level: High/Freshwater

Suitable for: outside use where the treated timber is in contact with heavy wet soil or in fresh water. Consequently, this treated timber is ideal for building substructures for walkways and jetties, etc.

Hazard Class Symbol: H4

Hazard level: High/in ground

Suitable for: outside in the ground, where wood is subject to periodic wetting and leaching. Consequently, this treated timber is ideal for wooden fencing, landscaping, stakes, etc.


Hazard Class Symbol: H3

Hazard level: Moderate / above ground

Suitable for: outside above the ground, where wood is subject to periodic wetting and leaching. Consequently, this treated timber is ideal for outside decking, stairs, homes, etc.


Hazard Class Symbol: H2

Hazard level: Low / internal

Suitable for: Inside above ground, where wood is protected from wetting and leaching. Consequently, this treated timber is ideal for roof trusses, internal structural timber, flooring, etc.
