ACQ® H3 and H4 

ACQ® is a preservative system that provides long-term protection to wood exposed to exterior applications. The system uses an Alkaline Copper Quaternary preservative that combines copper with an organic quaternary compound. This combination provides protection against a wide range of decay fungi, termites, and borers.


The preservative is applied to wood by pressure treatment, ensuring that the wood is thoroughly impregnated with the preservative solution. This makes the wood resistant to decay and insect damage, making it ideal for use in outdoor structures such as decks, fences, and landscaping.



ACQ® has been used commercially since 1991 and is widely used throughout Australia, Europe, Asia, and the United States. It is a proven technology that offers reliable, long-lasting protection for outdoor wood applications.

H2F Blue

H2F timber treatment is a timber preservation that is commonly used for construction timbers in areas south of the Tropic of Capricorn. H2F pine is blue in colour as Blue Treated Timber because of its distinctive blue color. H2f Blue is a dual action preservative, repelling termites, and if the treated timber is consumed, also acts as an effective insecticide.
