柚木

Teak has been used as a boat-building material for over 2000 years. In addition to relatively high strength, teak is also highly resistant to rot, fungi and mildew. In addition, teak has a relatively low shrinkage ratio, which makes it excellent for applications where it undergoes periodic changes in moisture. It is also prized for the trim work on boat interiors.

Because it is suitable for external use and for decorative use, it is highly prized.
