Our Products

We offer a comprehensive range of building and fencing material for the construction, D.I.Y and the agricultural sector, transmission poles for power distribution and communication systems as well as treated poles for vineyard and orchards throughout Southern Africa.

We use only the best quality matured gum trees. Pure Eucalyptus Grandis and Grandis Clone in the form of Eucalyptus Grandis x Urophylla. Our timber originate from sustainable forest and we ensure a full grading process as to deliver best quality. The copper-chrome-arsenic compounds are heavy duty wood preservatives covering a wide biological spectrum without leaching in soil. The copper is a fungicide and the arsenic are an insecticide plus a back-up fungicide. The chrome acts as a fixing agent, reacting in the presence of wood cellulose to render the copper and arsenic chemicals insoluble. CCA is applied by vacuum pressure, CCA impregnation and solution concentration can vary according to the desired retention required for specific conditions. CCA treated timber is odourless and can be readily painted or stained once dry. It has a characteristic light green colouration.

It is applied to our products within the following hazardous categories:

  1. H2 Pine: Timber Structural for interior above ground with CCA retention at 6kg per m3 of timber.
  2. H3 Laths and Droppers: Exterior above ground with CCA retention at 8kg per m3 of timber.
  3. H4 Ground Contact Poles: Timber that is in direct contact with the ground. Building and fencing. Minimum retention of 12kg per m3. Minimum preservative penetration of 13mm. Labeled and marked as H4.

Vineyard, Berry and Citrus Orchards – Due to required life expectancy and its exposure to commercial agricultural practices such as flood and other frequent irrigation methods, as well as fertilisers with high nutrients. Vineyard Poles are classified as extremely high risk Hazard Class 4 (H4) commodities and require additional chemical retention to ensure suitability. Thus 16kg per cubic metre.
