Quick Facts
Representative reference values — natural wood varies by growing region, moisture content and individual board.
Durability, Stability & Workability
Texture: Coarse
Workability: Machines, glues and finishes well; open pores telegraph through thin films.
Fastening: Pre-drilling recommended for screws and nails.
Finishing: Open pores take stain readily; use filler for a glass-smooth finish.
Color change: Pinkish tan ambers slightly with age.
Insect resistance: Susceptible to insects and decay
Ratings and published values are representative reference figures. Natural wood varies with growing region, moisture content and individual boards — treat them as guidance, not guarantees.

How lumber sizes are described
- Rough (4/4, 8/4…)
- Hardwood thickness in quarters of an inch as sawn, before surfacing. 4/4 = 1" rough.
- Surfaced (S2S/S4S)
- Thickness after planing. 4/4 typically finishes at 13/16" or 3/4".
- Nominal vs. actual
- Construction lumber is sold by nominal size; a 2x6 measures about 1-1/2" x 5-1/2".
- Random width / length
- Most hardwood is sold as it comes from the log — widths and lengths vary within a range rather than being fixed.
