6" x 6" #1 & Better Douglas Fir Green Rough Dimensional Lumber
This is a 6x6 in #1 & Better Douglas fir, sold green and rough sawn. It is not planed to a fixed finished size and comes in 10, 12, 16 and 20 ft lengths.
#1 & Better has fewer and smaller defects than #2 and higher design values. It is chosen for beams, headers, posts and other members that carry heavier loads. Span, load and local code decide the size you need, so confirm it with your building inspector or engineer. It is sold green and rough, so it shrinks as it dries, can check or twist, and the finished size varies, so check the size against your layout before you order.
Features and Common Uses
- No. 1 & Better grade, with fewer and smaller defects than No. 2 and suited to heavier construction
- Douglas fir is among the strongest and stiffest of the common softwood framing species.
- Green, with a moisture content above 19%, so it is soft to cut and drill
- Rough sawn, keeping the texture left by the sawmill for an exposed, rustic look
- Long 16 and 20 ft lengths for beams and long spans
- Not pressure treated, so it is for dry, above-ground use
Commonly used for:
- Beams, headers and posts
- Timber framing and heavy platforms
- Heavy joists and rafters
- Concrete forming and shoring
- Pergolas, arbours and landscape timbers
- Barns, sheds, and commercial and industrial construction

Rough-sawn timber is not milled to a fixed finished size, so actual thickness and width vary by piece and by sawmill. Grade and species are stamped on each piece and are the governing record for what you receive. Span, load and local code decide where the lumber can be used, so confirm with your building inspector or engineer. Green lumber changes size as it dries.

Frequently Asked Questions
What is the difference between this and an S4S 6x6?
This 6x6 is rough sawn and graded #1 and Better. A surfaced S4S 6x6 is planed smooth on four sides and is usually graded #2 and Better.
What does No. 1 and Better mean?
It is a visual grade. No. 1 and Better lumber has fewer and smaller knots and defects than No. 2, and the grade can include higher grades above No. 1. It is a step up from the #2 and Better stock used for general framing.
What is Douglas fir?
Douglas fir is a western softwood prized for its strength and stiffness. It is one of the most common species for heavy framing, beams and posts.
What does green rough mean?
Green means the timber has not been kiln dried and holds moisture above 19%. Rough means it is sawn but not planed, so the surface keeps its sawmill texture. Expect shrinkage as it dries.
What is the actual size of a rough 6x6?
It varies. Rough-sawn lumber is not planed to a set finished size, so the actual thickness and width differ from piece to piece. Contact us if a specific dimension matters for your project.
Can I use it outside?
Only where it stays dry and above ground, or for short-term use. It is not pressure treated, so it will rot in ground contact or constant wet. Choose pressure treated lumber for buried posts and outdoor structures.
