H3/H4 CCA Treated Pine
CCA treated wood is widely used throughout the world for a great range of applications. CCA (Copper Chrome Arsenic) treatment of plantation and re-growth timber has helped meet the demand of durable building products. Despite scientific reviews and changing government legislation, CCA continues to be registered and approved for a wide range of uses in Australia. Other treatments include ACQ & LOSP.
CCA treated wood is an environmentally friendly material. The treating process of CCA extends the life of the wood requiring fewer trees to be cut. It is pressure treated with a preservative to resist decay and insect attack.
ACQ (Alkaline Copper Quaternary) uses copper and ammonium compounds to defend Fungi and insect attack and is treated in a similar way to CCA.
H3 Treated Pine is for outside above ground use.
H4 Treated Pine is for outside in ground use.

- Always wear a filter mask and eye protection when machining, sanding or docking treated pine.
- Wear gloves at all times.
- If sawdust comes into contact with skin, wash immediately.
