HARD AND HEAVY MARINE LUMBER
Greenheart is not a particularly attractive lumber, and is valued mainly for its amazing natural durability and hardness. It is often the first choice for marine construction, particularly of boats and decking and is also used for bridges and jetties. Greenheart
is difficult to work, but is amazingly strong. It is used in situations where poor seasoning is not an issue - underwater, for instance - where it doesn't matter if the surfaces are not perfect.

Some certified greenheart is available.
AVAILABILITY AND COST
