Product Description

Pressure‑treated 4x6x20 nominal timber post (nominal 4 in x 6 in x 20 ft; typical actual dimensions ≈ 3-1/2" x 5-1/2") sold individually for heavy exterior and structural uses. Commonly surfaced on four sides (S4S) and graded No. 2 or No.2&Btr depending on supplier, these timbers are treated for ground-contact applications (preservative chemistry and infusion—e.g., MCA, CCA, wax finishes—vary by vendor) to resist rot, fungal decay and termites. Typical uses include fence and gate posts, deck support timbers, structural posts and heavy landscape timbers; finish/color options (cedar- or brown-tone) and species (Southern Yellow Pine, Hem‑Fir, Douglas Fir) vary by source—see vendor pages for exact grade, preservative and species details.
