Revolutionary Technology

TRUSTWood “Copper” uses revolutionary technology to pressure treat and colour infuse timber for decks, fences, landscaping, and general construction uses.

TrustWood “Copper” premium decking and outdoor products use Microshades technology which is a colour additive that is fully infused into the timber during the treatment process, achieving a rich colour while maintaining the natural appearance of the timber.

*TRUSTWood is produced with a Copper Azole preservative which offers a 50 year limited transferable durability guarantee against decay and insect attack assuring lifelong enjoyment of your timber, inside and out.


TRUSTWood Micro-pro Treatment is the first treated wood process to receive EPP (Environmentally Preferable Product) Status

TRUSTWood uses Micro-pro technology which is the first treated wood process to be certified under Scientific Certification Systems Environmentally Preferable Product (EPP) program based on Life-Cycle Assessment.

Largely Eliminates Copper Releases

Wood products treated with the process result in the release of 90% to 99% less copper into aquatic and terrestrial environments when compared to standard treated wood products. The very small amount released bonds readily to organic matter in the soil and becomes biologically inactive, thus effectively eliminating eco-toxic impacts.

TRUSTWood incorporates a pigmented colorant system & water repellent additives.
