How do WPC outdoor trash cans perform in earthquake resistance tests compared to steel ones?

When evaluating outdoor furniture for public spaces, seismic performance is a critical safety factor. So, how do Wood-Plastic Composite (WPC) outdoor trash cans perform in earthquake resistance tests compared to their steel counterparts? The results reveal a significant difference rooted in material properties.

Steel trash cans are renowned for their high tensile strength and rigidity. In simulated earthquake tests, they demonstrate excellent resistance to initial deformation. However, their inherent stiffness is also a weakness. When subjected to the violent, multi-directional shaking of a major seismic event, steel cans are prone to permanent denting, buckling, or cracking at stress points, especially welds. Once deformed, they may fail to function correctly.

Conversely, WPC trash cans, made from a blend of wood fibers and plastics, exhibit superior performance in key areas of seismic testing. The composite material possesses a degree of flexibility and high impact resistance. Instead of permanently deforming under stress, WPC cans can absorb and dissipate seismic energy through slight flexing. This elasticity allows them to withstand shaking and potential impacts from falling debris without sustaining critical damage. They are less likely to crack or become unusable after an earthquake.

Therefore, while steel offers initial rigidity, WPC trash cans generally demonstrate better overall earthquake resistance. Their ability to flex and absorb impact makes them a more resilient and durable choice for regions prone to seismic activity, ensuring functionality and safety post-event.
