The Holley family started treating wooden transmission poles in 1939. The original treatment plant is still on the same land purchased by Mr James Holley Sr in 1860. The original plant has been continuously renovated and up graded over years.
The first specialised transmission pole drying kilns in Africa were imported from Germany and installed in 1980 at the original plant. TTP has expanded the drying kiln capacity at three additional plants giving TTP the largest drying kiln capacity in Africa.
Over the past several years TTP has grown its pole processing capacity significantly from the original Broadmoor plant with the acquisition of the Cramond Plant, the Ashton Plant, the Ramanas Kilns and recently the Low Creek plant.
During the same time period of plant acquisition TTP and its associate companies have purchased significant commercial forest holdings in Kwa-Zulu Natal and Mpumalanga provinces of South Africa. Today TTP and its associate companies have some 17000 ha of commercial forests, have the rights to a further 15000 ha and timber swop agreements with South African Pulp and mining timber companies.
