Red Oak, Ash, Hickory, White Oak, Maple, Bambo, Birch, and American Cherry are the most common and are priced in the mid-range.
Exotic woods will be more expensive, softer woods are not as durable.

2 1/4" & 3 1/4" are standard mill. Anything wider is considered plank.

Some Woods come in 3 grades: Select (no knots to pin knots, not much variation in grain patterns, #1 (a few knots and varied grain patterns ),
#2 (knots and very rustic looking grain patterns.)

Please note: Some woods are not suited for Colorado's climate and are not listed here for that reason.
