Capacity of being impregnated

&;8226; Sapwood: Medium capacity of being impregnated
&;8226; Heartwood: No capable of being impregnated

Mechanization

&;8226; Sawing process: ordinary difficulties arise from hardness and abrasability
&;8226; Drying process: Slow. Low risk of deformation and high risk of crack formation.
&;8226; Planing process: Difficulties arise from hardness, abrasability.
&;8226; Gluing process: Tannins hamper proper adherence.
&;8226; Nailing and screwing process: pre-drilling is recommended due to hardness.
&;8226; Finish: No particular difficulties arise.
