What are the load-bearing capacities of stackable polypropylene outdoor trash cans?

Stackable polypropylene outdoor trash cans are engineered for durability and efficient space utilization in commercial and public settings. The load-bearing capacity typically ranges between 50-100 kg (110-220 lbs) per unit when stacked, depending on wall thickness and structural design. These containers utilize high-density polypropylene material that offers excellent weight distribution and impact resistance. Most industrial-grade stackable bins feature reinforced base rims and interlocking mechanisms to prevent shifting under load. Environmental factors like temperature fluctuations and UV exposure minimally affect their structural integrity due to polypropylene's weather-resistant properties. For optimal performance, manufacturers recommend maintaining even weight distribution and avoiding point loading beyond designated capacities. Common applications include municipal parks, restaurant waste management, and industrial recycling programs where vertical stacking maximizes storage efficiency. Regular inspection of stacking mechanisms and surface wear is advised to maintain rated load capacities over time.
