Flat Grain

A wood grain pattern produced when lumber is plain-sawn (cut tangent to the growth rings), resulting in broad, sweeping grain arches and cathedral-shaped patterns on the board face. Flat grain boards are the most common and least expensive cut, showing the widest variation in grain pattern. This cut is more prone to seasonal movement than quartersawn lumber but is preferred when a bold, natural grain appearance is desired.
