Can aluminum profiles be used for outdoor applications where they will be exposed to weathering?

Yes, aluminum profiles can be used for outdoor applications. They are resistant to corrosion and weathering due to their inherent properties and can be anodized or powder coated for additional protection against the elements. This makes them suitable for a variety of outdoor uses such as construction, furniture, and signage. However, it's important to ensure that the profiles are properly finished and maintained to prolong their lifespan and performance outdoors.
