ABOUT TANALISED TREATED PINE.

CCA is an acronym for Copper Chromium Arsenate and it was originally invented in the 1930’s by Dr Sonti Karmasan in India. Tanalith® CCA preservative has the proud record of being among the first industrial wood preservatives to be used in much of the Asia Pacific region up to 70 years ago and is still in wide use today. This remarkable preservative is still the preferred choice for wood in ground contact and other situations that demand the best long term resistance to decay, termites and even marine organisms.

  • Approved for all treatment levels up to and including H6.
  • Highly cost effective and with unmatched durability for ground contact and utility applications.
  • Record of use and performance going back 70 years.

Tanalith® O is a CCA preservative for protection of timber against beetle and insect attack and fungal decay. It has a long term, proven track record for efficacy when in concentration for the applicable hazard (H1-H6).

For what application is Tanalith® O suitable? Suitable for use for protection in all Hazard Levels (H1 – H6), Tanalith® O remains the preferred preservative for Posts and Landscape product (H4), Poles (H5) and Marine piles (H6). Tanalith® O has been restricted for use in H3 and some H4 situations where the treated wood product will be used for decks, handrails, outdoor furniture, children’s Playgrounds or other council or national parks projects requesting non-CCA treatment.

Yes Tanalised treated pine is safe to use. The preservative chemicals are toxic to insects and fungi, which is, of course, their purpose. Provided the common sense precautions are observed, preservative chemicals do not present a hazard to humans when fixed in the dried timber. Sometimes a white powder will appear on the surface of the timber. This is mostly sodium, solphate, a harmless substance which, if necessary, can simply be brushed or hosed off.
