MicroPro Sienna® brown pressure treated wood products are pressure treated with MicroPro® Micronized Copper Azole (MCA) to protect the wood against fungal decay and termite attack. The main ingredient in the preservative system is copper, which has long been known as an effective wood preservative. MicroPro Sienna uses micronized copper coupled with micronized tebuconazole for long-term protection of wood exposed in exterior applications.
MicroPro Sienna® Treated Wood is used in residential applications (decks, fences, freshwater docks and landscaping) above ground, in ground contact and in freshwater contact. The appropriate usage is noted on the end tag attached to each piece of MicroPro Sienna Treated Wood.
