Description

&;8226; Sapwood: yellowish white colour.
&;8226; Heartwood: reddish brown.
&;8226; Fiber: straight, occasionally slightly wavy.
&;8226; Grain: medium size.

Applications

&;8226; Interior and exterior furniture.
&;8226; Interior carpentry, doors, stairs, paneling, molding, baseboad, friezes, parquet flooring.
&;8226; Exterior carpentry, doors and windows.
&;8226; Interior and exterior carpentry.
&;8226; Decorative panels.

Capacity of being impregnated

&;8226; Sapwood: medium capacity of being impregnated.
&;8226; Heartwood: no capable of being impregnated.

Mechanization

&;8226; Sawing process: ordinary difficulties due to hardness.
&;8226; Drying process: quite slow. Low risk of deformation and crack formation.
&;8226; Planing process: easy. Risk of repelling on intertwined fibers.
&;8226; Gluing process: no difficulties.
&;8226; Nailing and screwing process: pre-drilling is required due to hardness.
&;8226; Finish: rubber deposits can locally hamper varnish adherence.
