The Urban Lumber Company hardwood grading system
Conventional lumber grading for hardwoods is a pretty complicated issue. I am not a certified lumber grader, but the system I employ is based off of conventional grading standards. There are several reasons for our departure from the standard. The existing system is in place to serve large scale operations where truckloads of lumber have to match each other, usually being shipped to industrial or commercial outlets to be used in manufactured goods. Our target market is not these billion board foot users, but area craftsmen seeking an interesting and viable source for local hardwoods. Our grading standards are designed for this group of consumers, where individual selection and interesting defects are part of the process.

The table below attempts to outline our grading system in relation the standard hardwood grading system. The illustrations and photos are provided to serve as examples for a given grade.

Grade A: This is the best grade of board we offer. It is a combination of the traditional catagories of Firsts, Seconds and Selects. In general terms these boards are free from major defects over a good percentage of the board the board foot measurements are taken from, about 85% or so. It will vary, but in general these boards will have wider clear faces, be longer in length, and less prone to twist, cup and bow than any other grade.


Grade B: This grade is simlar to a mix of Selects and #1 Common. These boards will still yield good lumber, but in general there may only be about 65% or so of the board that is clear, the remainder could be lost to checking, twist, bow, cupping, stain, or knots. If you are working on a large project with a lot of medium to small pieces, buying a lot of this grade may make sense because it would be an economical way to get a large selection of wood to pick through.


Grade C: This grade is similar to #2 common. The maximum size of the cuttings likely yielded from a board of this grade would be 3" x 2' or so. This is the lowest grade we sell that is not conisdered utility wood. These boards may have great sections in them, accompanyied by wild staining, twisting, or knots.

Grade D: This is the lowest grade we sell, suitable for utility purposes. These boards may have checking, or other obvious defects.

An "A" board pictured above. The red area inset in the lower section is the clear area where the Board Foot measurement is taken from. Within that 8 x 48 area it is at least 85% clear.
This board "10-7" is graded "C" because it has a check that runs its length. The edge view, photo left, shows two short pretty straight pieces connected by a knot. With careful project planning this board could produce several small straight grained pieces of beautiful wood.
