Technical Notes

Intended Use

Ironwood Fencing treated pine fencing products are typically used in external boundary fencing applications.

Treatment Durability

The majority of our fencing products are treated with Copper Chrome Arsenate (CCA).

Ironwood Fencing is available in different levels of treatment. These are known as hazard classes and range from H1 to H6. The hazard class refers to the environmental hazards the timber can be exposed to while still expecting long term performance.

Ironwood Fencing is approved for use in all areas of Australia.


Ironwood Fencing is coloured green for ease of identification and each pack is branded with its treatment type, treatment hazard level and treatment plant on the pack label.

Reseal Requirements

In any application where Ironwood Sleepers has been cut, notched, rebated or drilled the exposed area should be resealed with an appropriate reseal product to ensure the treatment envelope remains intact and provides the best long term protection.

  • We recommend PROTIM® SOLIGNUM® CN TIMBER OIL.  This is a copper-based solvent/oil formulation that is green in colour. If applying to the cut ends treated products the timber will initially have a green colour, however this will dull to brown after a short period of weather exposure.  If a paint system is to be applied after resealing, allow time for the CN oil to be absorbed and then follow the paint manufacturer’s recommendations.

For more information please refer to the PROTIM Solignum Timber Care Technical Data Sheet available from Koppers Performance Chemicals.

Fixings & Fasteners

For normal applications all bolts, screws, nails, brackets, framing anchors and other fixings that will be in contact with preservative treated pine should be hot dipped galvanised. In harsh environments such as those close to the sea, stainless steel or similar fixings should be used.


Ironwood Fencing has been treated to make it suitable for outdoor use. The treatment protects the timber from fungal decay and insect attack but not from weathering. Weathering will cause the timber to turn a silver-grey colour and some surface checking and splitting may occur; however, this can be reduced by the application and regular maintenance of coatings such as paints and stains.

Always check the label of the finishing product and follow the manufacturer’s instructions.


Paint offers the most protection, generally providing for the longest interval between recoats (up to 10 years) and is recommended as the best form of additional protection. 

Stains & Clear Coatings

Exterior coatings furnish structures with an aesthetic finish, however their primary function is to provide protection against the elements.

The application of a protective coating to both treated and untreated timber surfaces in exposed situations reduces the effects of weathering by slowing the rate at which timber takes up and loses moisture; this in turn lessens the severity of any checking.

Protective coatings include products that penetrate the timber as well as those which only provide a surface film. Please follow the coating manufacturer’s recommendations.


When handling and working with Ironwood Fencing products, users are recommended to wear gloves, dust masks, ear protection and safety glasses at all times. Please refer to Material Safety Data Sheet (MSDS) below for full details.

Waste Disposal

Off-cuts can be disposed of as normal landfill waste. Do not burn treated timbers. Please refer to Material Safety Data Sheet (MSDS) for full details.
