What Are the Different Classes of Hardwood Lumber? | By Oswald Lumber

Depending on the project, hardwood may be the best choice. While it tends to be stronger than softwood lumber, it’s found in a much smaller supply, making it more expensive. There are, however, different classes of hardwood that may make your project more affordable. Oswald Wholesale Lumber sells lumber near you at our building supply in Columbia, SC. Here are a few facts about the different classes of hardwood lumber.

Understanding How the Classes Are Determined

First, let’s find out how the different classes of hardwood are determined. Unlike softwood, the largest factor in grading a piece of hardwood comes down to its appearance. One side of the wood will always look finer than the other. The bigger the difference between the two sides, the higher the number grade and the lower the quality.

Number 3 Select

This is the lowest classification for hardwood lumber. This means that your hardwood lumber is 33% free of imperfections.

Number 2

If your hardwood has this classification, it means that it is 50% of free of flaws.

Number 1

This is the second-highest grade of quality, with 66% of the wood being clear of impairments.


This brings us to the last, and finest, grade of hardwood: FAS. FAS stands for First And Second. The wood must be 83.3% free of imperfections on a larger board than the other three classifications require.
