Barn beams are rough sawn with circular sawmarks or hand hewn with ax marks. They come in a variety of lengths and dimensions ranging from 4"x4"-16"x16". They have a rustic look with lots of character. You will often find old mortise and tenons, nail holes, and sometimes original wooden pegs. The most common species are Oak, Beech, Poplar, and Heart Pine. They are commonly used on ceilings, walls, or to frame out doorways and openings.
