Alder is a soft wood and sometimes contains knots. This species is considered a great option for laser cutting and engraving and produces and nice dark burn when engraved. When finish is applied, Alder darkens quite a bit and can looks similar to Cherry. Alder trees do not grow very large, so we rarely carry stock wider than 6".

Surfacing: Planed smooth on two sides. Not sanded.
When lumber is cut at a lumber mill, the thickness is traditionally measured in quarters of an inch. For example, 4/4 equates to 1 inch and 8/4 equates to 2 inches thick.
When you order alder lumber from us, it is surfaced on both sides (S2S), resulting in a loss of about 3/16 of an inch in thickness.
4/4 lumber will come surfaced to 13/16" thick, and 8/4 to 1 & 13/16".
After sanding or shaping, you should be left with about 3/4" workable material.

S4S means the lumber will be surfaced on four sides—it is planed smooth on the top and bottom face with both edges trimmed straight and to size.
All S4S and S2S lumber is planed but not sanded. It will need sanding before a finish can be applied.

All our Lumber is Select and Better (Sel&Btr) grade unless otherwise specified. Select and Better is the highest grade available.
Most pieces will be 83% to completely clear. Small peices are usually completely clear, while larger pieces might have small defects or a few sound knots.
