Outdoor Structure Timber

Pergolas, pavilions, carports, entry gates, covered patios — Douglas Fir delivers the scale and character that makes outdoor structures worth building.

Outdoor Performance You Can See

Douglas Fir's density and tight grain make it exceptionally durable for outdoor applications. It weathers to a natural silver-gray without structural compromise — and with proper finishing, retains its warm amber tones indefinitely.

We supply outdoor structure manufacturers and contractors with the standard post sizes they need in quantity — 8x8, 10x10, 12x12 — as well as the specialty sizes that set premium builds apart.
