When selecting urban trash bins, lifespan is a crucial factor. Polymer (plastic) bins typically last 5-10 years in municipal settings. Modern polymers contain UV stabilizers that resist sun damage, and they won't rust or corrode. However, they can become brittle in extreme cold and may crack under severe impact. Their lighter weight makes them easier to handle but also potentially more prone to tipping.
Metal trash bins, usually made from galvanized steel or aluminum, generally offer a longer service life of 10-20 years or more with proper maintenance. Galvanized steel provides excellent strength and rodent resistance. The primary threat is corrosion, especially if the galvanized coating is scratched or in coastal areas with salt air. Regular touch-up painting can significantly extend their life. Metal bins are heavier, more stable against wind, but can dent.
The expected lifespan of either type depends heavily on usage intensity, climate, and maintenance. Polymer bins excel in chemical resistance against waste acids, while metal bins better withstand physical abuse. Many cities use a mixed fleet, placing polymer bins in lower-impact areas and metal bins in high-traffic or vandal-prone locations. Proper cleaning and immediate repair of minor damage will maximize the lifespan of both materials.
