IRON WOOD (Eusideroxylon zwageri)
Iron wood (locally named Ulin) or sometimes called
"Belian" is an extremely durable hardwood often used for marine
works and heavy construction works. Since the last 5 years Iron wood has
gained an enormous popularity as a building material for wood houses. The
wood is extremely strong and has a high rated capacity for the use as
structural members. The wood is 100% immune to termite attacks.
Iron wood has a service life time of some 50 to 100 years
in ground contact. Iron wood in the open has a life time of some 80 years,
even when constantly sprayed by sea water. The wood is therefore an ultimate
solution for structures close to open sea.
The wood texture of Iron wood is fine and even. The
grain is straight and only slightly interlocked, somewhat lustrous. The wood
has a lemon-like odor that persists. The heartwood is light brown to almost
bright yellow when freshly cut, darkens on exposure to a deep reddish brown
to very dark brown.
Iron wood has a very high strength and durability, is
hard and heavy with high stiffness and shock resistance. Excellent
decay resistance and dimensional stability.
