One of the very first questions we ask most customers when they contact us is either "What grade are you looking for?” or something less direct along the lines of “What are you building with this material?”. While lumber is an excellent renewable resource, it doesn’t make sense to throw beautiful lumber at every project. So at Marks Lumber we offer lumber of all qualities, and work with every customer to make sure they get material that will work well for them. So we have to determine what type or quality of lumber you need.
The way we deliver the right product is by grading all our timber products. Marks Lumber uses the standard grade guidelines maintained and published by the Western Wood Product Association (WWPA).
Lumber is graded relative to how it will be used practically. So lumber for different purposes is graded differently. Generally lumber is graded by characteristics that affect strength and appearance.
Lumber that is 2 inches or thicker is graded for both strength and appearance. Lumber and lumber products that are less than 2 inches thick are only graded for appearance.
Products manufactured at Marks are graded manually by well-trained graders. For stock items and blanks for planed items, Marks sets up and grades a specific dimension. For example, let’s just say 1x6x8. Generally, normally, and usually the grader will call boards into 4 grades.
When grading beams or 2 inch material we stock 3 grades:
At Marks Lumber, we want to deliver quality material with value. To do that we grade lumber and sell the right lumber for the job at hand.
People generally can tell if an individual board or timber is going to get the job done. What grade is it?
If you are using the material for trim or furniture you will need a #2 and better grade.
Siding? We generally recommend #2 and better for homes and commercial buildings. For outbuildings and agricultural buiildings, #3 is fine.
Fencing? Grade #3 for nicer fences; but for windbreak lower grades are acceptable.

Note: The WWPA grade book anticipates 5% error for grading mistakes and material that ‘moves’ significantly after grading.
