Outdoor trash cans are a type of public facility mainly used to hold garbage and waste, often placed in outdoor public places such as parks, roadsides, residential areas, schools, etc. Compared to indoor trash cans, they have higher durability to cope with harsh natural conditions such as sunlight, wind and rain, frost, etc. Outdoor trash cans are usually made of materials with better durability, such as stainless steel, cast iron, reinforced concrete, etc.

The history of trash cans can be traced back to ancient times, but at that time they existed more as simple waste containers. With the advancement of industrialization and urbanization, the problem of garbage is becoming increasingly prominent, and the design and function of garbage bins are also gradually receiving attention. From the initial wooden and iron trash cans to modern materials such as plastic and stainless steel, the materials used in trash cans are becoming increasingly diverse, and the design is becoming more user-friendly.
