8" x 8" #1 & Better Green Rough Fir Dimensional Lumber
This is an 8x8 in No. 1 & Better fir, sold green and rough sawn. It is a heavy timber size in 10, 12, 16 and 20 ft lengths, used for posts, beams, timber framing and landscape structures.
Green and rough means it is not dried or planed. The timber still holds its moisture, so it shrinks and can check or twist as it dries in place. The surface keeps its sawn texture and the finished dimensions vary from piece to piece, so check the size against your layout before you order. Contact us if you need a dimension confirmed.
Features and Common Uses
- No. 1 & Better grade fir, a grade with fewer and smaller defects than No. 2 and suited to heavier construction
- Green, with a moisture content above 19%, so it is soft to cut and drill and costs less than kiln-dried timber
- Rough sawn, keeping the texture left by the sawmill for an exposed, rustic look
- An 8 in. square section for heavy posts, beams and timber-frame members
- Not pressure treated, so it is for dry, above-ground or temporary use
Commonly used for:
- Posts and beams for pergolas, barns and timber-frame structures
- Exposed beams, mantels and rustic timber features
- Landscape timbers, retaining edges and steps above ground
- Heavy cribbing, shoring and forming

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. Post and beam sizing depends on span, load and local code, so confirm it with your engineer or building inspector.
Frequently Asked Questions
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 does No. 1 and Better mean?
It is a visual grade. No. 1 and Better timber 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 the actual size of an 8x8?
It varies. A rough-sawn 8x8 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.
Will it crack as it dries?
Some surface checking is normal in large green timbers as they dry, and it is usually cosmetic. The timber can also twist or shrink, so allow for movement in your design and stack it flat with spacers if you store it.
Can I bury it in the ground?
No. 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.
