Don't be tricked into believing that gum poles are simply just "black painted" wood logs. Oh, no brother Gum poles found in South Africa are exclusive specimens. To start with they are grown in contracted plantations to specs of the manufacturer. This is significant since the producer has to conform to SABS (South African Bureau of Standards) specs on the poles produced.

So, the entire process of gum poles commence with the selection and grading of the timer in the plantation by the manufacturer. In terms of the SABS standards poles should be measured for defects, they need to undergo strength tests and the dampness content needs to calculated before treatment can commence. So, at this initial phase the quality of the pole is set according to the SABS specifications. Production plants are audited fairly often by the SABS to ensure submission to standards.

Along with the SABS standards manufacturers further ought to adhere to the typical specifications of users like Telkom, Eskom among others. Further consider the fact that there's a log home sector in South Africa which also set their high standards on log manufacturers.

As soon as the wet gum poles are sent to the producer, the poles must be dried. They are either air dried or they are kiln dried, and after that they again are graded. Once dried the gum poles should be treated. They are either Creosoted or tanalised in accordance with the end- user requirements.

The treatment process entails a treatment vessel (bath) to which the poles are filled and subjected to high pressure and extreme temperature when the preservative is added. Pressure is maintained up until the preservative has reached the mandatory preservative absorption is reached. The preservative is then pumped from the vessel and a vacuum designed to allow the gum poles to "surface dry".

On release from the treatment vessel the gum poles are again inspected to ensure a minimum penetration of 15 mm of preservative, where after the ends are clad with a metal disc in order to avoid the ends from splitting.

So, by the time you buy your gum poles from the timber yard you receive a quality product that you can tackle your project in the full knowledge that you have a merchandise that will withstand weather conditions and any attack by insects, like termites. Creosoted treatment gives the characteristic black colour to gum poles, while the tantalised variety retains the colour of the natural wood.

Gum poles are wonderfully versatile in their use and require the minimum of tools for construction purposes. With a drill, a saw, a hammer, wide chisel and bolts and nuts plus a spanner you can construct. Gum poles can be used for the construction of homes, cabins, garden sheds, swings for the children and fences, in fact anything else that you can think of. A tree house or a Wendy house will see to it that you get an extra hug and kiss from the child.

How to please Mom? Well maybe a few flower boxes or an outside counter by the braai or a new fence or a lapa - a bit of imagination can go a long way
