Standard Dimensions
a) Cross-sections: 4x6 to 10x10 (larger cross-sections up to 18x18 are sometimes available, depending on length and quality needed); b) Lengths: to 16' (longer timbers are often available); c) Target Dimensions: Circle-sawn timbers are generally targeted at 1/2" nominal dimensions; d) Tolerances: +/- 1/4". As timbers air dry, they tend to shrink somewhat, resulting in dimensions become somewhat more nominal.

Typically, approximately 3 pounds per board foot
Grading
Douglas Fir Rustic Timbers can often be graded (generally WCLB) upon request. It is highly recommended that any timbers that are to be used in a structural application be graded. It is also recommended that standard size timbers be used whenever possible. Checking tends to be more pronounced in timbers wider and/or thicker than 12" than in standard size timbers.
Appearance Variation
Douglas Fir Rustic Timbers are cut from logs or timbers that may vary in appearance from piece to piece. As a result, timber characteristics can be expected to vary from piece to piece. Trestlewood believes that appearance variations (no two timbers exactly alike) are one of the selling points of this product line.
