How long will aluminum last outside?

Aluminium is renowned for its durability and long lifespan, even when exposed to the elements. When properly maintained, aluminium can last for decades outside. Its natural resistance to corrosion makes it an excellent choice for outdoor applications like aluminium ceilings and aluminium facades.

One of the main reasons aluminium lasts so long outdoors is that it doesn't rust in the traditional sense. While aluminium doesn’t rust outside, it forms a protective oxide layer when exposed to air and moisture. This oxide layer prevents further corrosion, making aluminium resistant to weathering, even in harsh environments. However, in certain conditions, such as in highly acidic or salty environments (like coastal areas), aluminium can experience some surface degradation. Regular cleaning and maintenance can help extend its life.

In general, aluminium can last anywhere from 20 to 50 years depending on environmental conditions and the type of finish used, making it a highly reliable material for outdoor applications.
