Spruce Pressure Treated Wood

Product Description

Spruce pressure-treated wood is softwood lumber—typically White or Sitka Spruce—that has been infused with preservative chemicals under high pressure to protect it from rot, insects, and moisture damage. It’s a popular choice for above-ground outdoor projects where a clean appearance and easy handling are key.
