What are the thermal shrinkage rates of eucalyptus wood in outdoor trash cans exposed to freezing temperatures?

Eucalyptus wood, commonly used in outdoor furniture and trash cans due to its durability and natural resistance to decay, undergoes dimensional changes when exposed to freezing temperatures. The thermal shrinkage rate primarily depends on the wood's moisture content, grain orientation, and specific environmental conditions. Typically, wood experiences shrinkage as temperatures drop below freezing because water within the cell walls freezes and causes contraction. For eucalyptus wood, the tangential shrinkage rate (across the grain) can range from 5% to 7%, while radial shrinkage (along the grain) is generally lower, around 3% to 4%, when temperatures fall to -10°C (14°F) or below. These rates may vary based on the wood's initial seasoning and treatment. In outdoor trash cans, this shrinkage can lead to issues like cracking or warping, potentially compromising structural integrity. To mitigate effects, proper sealing and regular maintenance are recommended. Understanding these factors helps in selecting and caring for eucalyptus wood products in cold climates.
