Timber and wood are sensitive materials and thus need to be treated with preservatives to improve resistance to attacks by wood destroying fungi and insects. The treatment of timber enhances its durability to a level which is suitable for it's intended use. Furthermore treated poles should be protected from other external elements such as the weather through the application of coating or oil. There are a variety of ways in which poles can be treated according to the environment the pole is exposed to. Where some treatments protect timber against borer or termites, others protect against insects and decay.

Types of Treated Poles

Creosote Treatment: One of the most common ways to treat timber is through the Creosote Treatment Process. Coal-tar creosote is valued in its toxicity towards fungi, insects and marine borer as well as its natural water repellant quality. It is commonly used to preserve and waterproof cross arms, pilings, telephone poles, transmission poles, marine pilings and fence posts. This is done using the "full-cell process" or "empty cell process".

Copper Chrome Arsenate Treatment: Copper chrome arsenate (CCA) treated poles are timber that has been preserved with a substance containing copper, chromium and arsenic. This specifically prolongs the life of wooden poles that need to stand the test of time. This treatment method has been safely used for over 60 years having been invented in 1993. CCA treated poles have gained popularity due its low conductivity, low corrosion and combustibility resistance. This is both a cost effective and environmentally friendly method of treating poles as it prolongs the life of the pole, has no offensive odour and will not contaminate the soil surrounding the treated pole. Both of the above methods are available at the R&B Timber Group.

All R&B Timber Group products meet the relevant SABS specification and ISO9001 standards, against pest, insect & fungal infestation. This ensures that you receive only the highest quality and professionalism for your treated poles.
