The Tree
The trees can grow to a height of 24m to 27m. The bole is often twisted or fluted with a diameter of 0.6m to 1m. In continental Europe the trees are often coppiced, providing smaller, fast grown sections. Older, larger trees often have a rotten heart.

The Timber
The sapwood is narrow and clearly defined from the heartwood which is greenish in colour when freshly cut, turning golden-brown after drying. The timber is heavy and hard, although the texture is coarse due to the contrast between porous earlywood and dense latewood. The grain is usually straight.

Drying
Slow to dry with a marked tendancy to distort.

Strength
Comparable to oak in general strength properties and similar to ash in toughness.

Working Qualities
Medium - difficult, due to the contrast in soft earlywood and hard latewood bands. A good finish can be achieved but it is difficult to nail.
