For over seven years now, Croft Timber has enjoyed increased export demand for the higher density of Northland Radiata Pine Poles for the utility markets in Asia and on occasion, further afield.

UTILITY POLES

Croftpoles are CCA (Copper Chromium Arsenate) treated to the level of Hazard Class 5 (H5) for critical end use situations. Results have shown that poles treated appropriately will have expected average service lives in excess of fifty years. Durability monitoring to date has shown that best results have been achieved with pine poles treated with either CCA or Pentachlorophenol (PCP) oil, however there are economic and environmental disadvantages associated with PCP.

It is for this reason that CCA is the only treatment of utility poles undertaken in New Zealand today and is unlikely to change in the forseeable future.

Almost 1,700 poles were tested in a Forest Service survey with species such as Larch and Douglas Fir showing very poorly.

MARINE PILES

Croft Timber Company has been a leader in the marine treatment market for some years now. Product is carefully monitored and sent for independent analysis to ensure it meets the very stringent standards for marine treated timber in New Zealand. We have been successful tenderers in projects such as the Americas Cup Village in Auckland City, Gulf Harbour Marina, Mount Maunganui Marina, Opua Marina (Northland) and many other smaller projects from Northland to the Hauraki Gulf to as far afield as Wellington, Australia, Maldives, and the French polynesian and South Pacific Islands.
