What are the thermal expansion properties of eucalyptus wood in outdoor trash cans exposed to temperature fluctuations?

Eucalyptus wood demonstrates notable thermal expansion properties when used in outdoor trash cans exposed to temperature fluctuations. As a dense hardwood, it generally exhibits moderate linear expansion compared to other wood species. The wood's cellular structure, characterized by interlocking grains and natural oils, provides inherent resistance to dimensional changes. However, like all organic materials, eucalyptus expands when absorbing moisture during humid conditions and contracts during dry periods. This movement is typically more pronounced across the grain than along the length of the wood. Proper design considerations, including expansion gaps and appropriate finishing treatments, can significantly mitigate potential issues. The wood's natural durability and stability make it suitable for outdoor applications, though seasonal movement of 1-3% can be expected depending on specific environmental conditions and wood processing methods.
