MicroPro® MCA Treatment
Much of our pressure-treated lumber uses MicroPro® technology with Micronized Copper Azole (MCA). This innovative process infuses wood with micronized copper particles and biocides, providing long-lasting protection against fungal decay, rot, and termites.
- Eco-Friendly Innovation – Koppers MicroPro® technology is the first treated wood process to be EPP (Environmentally Preferable Product) certified by Scientific Certification Systems based on a Life-Cycle Assessment.
- Cleaner, Natural Look – Micronized copper particles penetrate wood fibers more smoothly, creating a cleaner, more natural appearance compared to traditional treatments.
- Versatile Applications – Ideal for decks, fences, landscaping, and outdoor structures, MCA-treated lumber is a reliable choice for residential and commercial projects.
