Can aluminum profiles be used for outdoor applications? If so, why?

Yes, aluminum profiles can be used for outdoor applications. They are suitable for outdoor use due to their high resistance to corrosion, which is a result of the natural oxide layer that forms on aluminum when exposed to air. This layer protects the aluminum from further oxidation and damage. Additionally, aluminum profiles are lightweight, strong, and can withstand various weather conditions, making them ideal for applications such as outdoor furniture, construction, and signage. Their durability and low maintenance requirements also contribute to their popularity in outdoor settings.
