Plain sawing, also commonly called flat sawn, is the most common lumber you will find. This is the most inexpensive way to manufacture logs into lumber. Plain sawn lumber is the most common type of cut. The annular rings are generally 30 degrees or less to the face of the board; this is often referred to as tangential grain. The resulting wood displays a cathedral pattern on the face of the board. Boards are more susceptible to cupping and shrinkage, and which have a distinctive grain which may be aesthetically undesirable for some uses.
