Quick Facts
Representative reference values — natural wood varies by growing region, moisture content and individual board.
Durability, Stability & Workability
Texture: The texture is coarse with a straight to interlocked grain.
Workability: It is considered difficult to machine and prone to blunting cutters.
Fastening: Pre-drilling recommended for screws and nails.
Finishing: It is difficult to stain evenly due to resin pockets.
Color change: It generally holds its color well but can weather to a dull gray.
Insect resistance: It has moderate resistance to decay and insects.
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.

- 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.
