Uses and applications
Originally it was used in applications where resistance and durability were required, such as in naval and civil construction,
flooring, telegraph posts, docks, bridges, carts and carriages, tool handles, railway sleepers, etc.
Now it is used in new carpentary and furniture uses too.
