Roundwood Production Process

Pinepac prioritises environmental responsibility and strives for a net positive impact on the environment. We utilise sustainable resources and advocate for best practice manufacturing methods to uphold this commitment.

At our Roundwood plant, we focus on producing posts and poles from local pine forests, including utilizing production thinnings and small logs that would otherwise be wasted. Logs undergo processing through a peeler to remove bark and some fiber, minimizing taper and rough surfaces. The resulting peelings are repurposed for landscaping, planting, and farm animal winter pads to enhance paddock conditions during wet months.

After grading for size and defects, logs are dried using steam in a pressure vessel and treated with preservative chemicals, such as CCA or ACQ formulations, to prevent insect and fungus attacks. Our treatment plant adheres to industry best practices, with bunding to prevent chemical spills and regular inspections by regulatory authorities like Worksafe.

Posts treated to Hazard Class 4 (H4) are primarily used for farm fences, vineyards, and small retaining walls, while poles treated to Hazard Class 5 (H5) serve structural engineering purposes such as foundations and large retaining walls. Marine piles undergo treatment to Hazard Class 6 (H6) to withstand saltwater organisms and rapid decay due to shifting tides.
