Beech Timber

Beech (Fagus sylvatica)

 

General description

Beech is a Western European species found up to an altitude of 1500 meters and up to 60 degrees northern parallel. The trees grow to 35 m in height with diameters ranging from 40 – 90 cm.

 

 

Wood description

The colour is creamy white to pale pink and gets more red due to higher drying temperatures or when exposed to steam. The heartwood is not demarcated from the sapwood. Sometimes there are reddish areas near the heart.

Beech is a diffuse porous timber but annual rings and rays are clearly visible. Bosnian beech is one of the best in the world, and it´s known by it´s workability, durability and is very hard and heavy with very good strength properties. It has straight-grained consistency with uniform fine texture and color.

Machining is well, gluing is good, nailing and screwing is good, but pre-boring is necessary also has very good properties for bending in processing of bent furniture.

Common uses

Beech is one of the most important European hardwoods.
Its common uses are furniture, flooring, stairs, and bent wood for furniture.
