It is mainly used for artificial ships, bridges, railway pillow woods, railways, carriages, furniture, agricultural tools, floor panels, furniture, textile appliances, sports instruments, barrels, pole wood, pile wood, pillars, etc. Essence In Australia, the blue eucalyptus used in the train can be used for at least 20 years. This use has high requirements for the elasticity and strength of wood. In Graphiba (Australia), the house built with eucalyptus is still intact after 30 years.
