Quercus petrea, Quercus robur

 

General description

Oak trees are one of the dominant broad-leaved species of temperate Europe. The trees grow 20 – 30 m in height with diameters ranging from 40 – 80 cm.

 

 

 

Wood description

Sapwood is thin, between 1 to 4 cm, and white.The clearly demarcated heartwood is light brown to dark brown. Oak is mostly straight grained with a medium to coarse texture.


Annual rings and rays are clearly visible, oak is a ring porous wood.

 

European White Oak is a hard and heavy wood with medium strength properties.

 

Machining is well, nailing and screwing properties are good, but pre-boring is necessary. Gluing must be done with care, the wood is dense, slightly acid an rich in tannins.

Common uses

European White Oak is one of the most important hardwoods and is mainly used for furniture and flooring. It is also used for stairs, windows and doors and also for external paneling.
