Types of Lumber
The orientation of the woodgrain on a piece of
wood has a large impact on the attributes of the
lumber. Whether it is for structural, aesthetic, or
economic reasons, it is important for a sawyer to
know the output of their labors.
Flatsawn Lumber (Plainsawn)
Flatsawn lumber is characterized by woodgrain
that is less than 45° to the face of the lumber,
called "tangential grain."
This often results in unique cathedral patterns on
the face of the lumber. However, the tangential
grain contributes to more cupping and twisting
during drying. Because flatsawn lumber is fast-
est and most plentiful to produce, it is the most
affordable lumber on the market. The majority of
construction quality lumber is flatsawn.
