Description

&;8226; Sapwood: Yellowish white to pinkish white, clearly distinct
&;8226; Heartwood: yellowish gery to reddish grey
&;8226; Fiber: Straight, frequently intertwined or very intertwined
&;8226; Grain: Slightly/occasionally interlocked to highly/frequently interlocked

Tali

Applications

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

Capacity of being impregnated

&;8226; Sapwood: Medium capacity of being impregnated
&;8226; Heartwood: Low capacity of being impregnated

Mechanization

&;8226; Sawing process: ordinary difficulties arise from hardness
&;8226; Drying process: very slow. High risk of deformation and lower risk of crack formation
&;8226; Planing process: Difficult due to its hardness and to the risk of repelling and splinting. Slow mechanisation is highly recommended
&;8226; Gluing process: Tannins hamper proper adherence
&;8226; Nailing and screwing process: pre-drilling is recommended due to the hardness
&;8226; Finish: Rubber deposits can locally inhibit varnish adherence
