How do aluminum outdoor trash cans compare to plastic ones in terms of UV degradation?

When comparing aluminum and plastic outdoor trash cans in terms of UV degradation, aluminum demonstrates clear superiority. Aluminum trash cans are inherently resistant to ultraviolet radiation from the sun, maintaining their structural integrity and appearance for years without significant deterioration. The material doesn't become brittle or fade noticeably when exposed to prolonged sunlight.

Plastic trash cans, particularly those made from standard polyethylene, suffer considerably from UV degradation. Without UV inhibitors added during manufacturing, plastic bins become brittle, fade in color, and may develop cracks after extended sun exposure. Even with UV stabilizers, plastic trash cans typically show signs of deterioration sooner than their aluminum counterparts.

The molecular structure of aluminum makes it naturally resilient to sun damage, while plastic polymers break down when exposed to ultraviolet radiation. This fundamental difference means aluminum outdoor trash cans generally offer longer service life in sunny conditions, better maintaining their aesthetic appeal and structural strength over time. For permanent outdoor placement in areas with intense sun exposure, aluminum represents the more durable choice against UV degradation.
