The same rustic grade white oak, with circle saw marks across the face instead of a planed surface. You get texture and shadow overhead while the color stays in a narrow range. Lock mitered, unfinished, built to order in any custom size.
Texture Without the Color Swing
This is the option people land on when the smooth oak beam looks too finished and the hemlock looks too rough. The blade marks give the face relief and shadow, while the wood underneath stays in a controlled color range.
On a ceiling that distinction matters. A beam is seen from below and usually from ten feet away, so texture reads long before color variation does. Circle sawn gives you most of the visual effect with none of the unpredictability.
