6" x 6" #2 Grade Hem-Fir Green S4SEE Dimensional Lumber
This is a 6x6 in No. 2 grade hem-fir, sold green and surfaced on four sides with eased edges (S4SEE). It is a heavy post and timber size in 8 and 12 ft lengths, used for posts, landscape structures and framing.
This stock is green. It still holds moisture above 19%, so it shrinks and can check or twist as it dries, and the finished size settles slightly under the size it is cut at. Hem-fir is a lighter, softer wood than Douglas fir, so it suits dry, above-ground use and is not rated for ground contact.
Features and Common Uses
- No. 2 grade hem-fir, a framing grade used for structural and non-structural work
- Hem-fir is a species group of western hemlock and true firs, light in weight and easy to work
- Green, with a moisture content above 19%, so it is soft to cut and nail
- S4SEE means surfaced on four sides with eased edges, so the corners are slightly rounded and easier on the hands
- Not pressure treated, so it is for dry, above-ground use
Commonly used for:
- Posts for pergolas, porches and covered structures
- Beams, headers and timber framing in dry locations
- Landscape timbers, steps and raised edging above ground
- Concrete forming, cribbing and shoring

Grade, species and moisture marks 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. Green lumber changes size as it dries.
Frequently Asked Questions
What is hem-fir?
Hem-fir is a commercial species group made up of western hemlock and true firs such as amabilis fir. The wood is lighter and softer than Douglas fir, and it is graded and sold together as a single group.
What does S4SEE mean?
S4SEE means surfaced on four sides, eased edges. All four faces are planed smooth and the long edges are slightly rounded, so the timber is easier to handle and shows less splintering at the corners.
What does green lumber mean?
Green means the timber has not been kiln dried and holds moisture above 19%. It is easy to cut and nail, but it shrinks as it dries and can check, twist or cup.
What is the actual size of a 6x6?
Green 6x6 stock is surfaced a little larger than dry stock, at about 5-5/8 in. x 5-5/8 in., and it settles toward 5-1/2 in. x 5-1/2 in. as it dries. Contact us if a specific dimension matters.
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.
