As a material, aluminium is of course water-resistant but there’s a high chance for it to suffer corrosion when exposed to salty air. Therefore, if you’re the owner of a beach house and you are thinking about deploying colored aluminium frames, then that would be a bad idea. Aluminum is friendly with almost everything, but salty air and salty water. The corrosion caused by these elements also impacts the hardware quality and performance.

In other words, aluminum profiles with relatively thick surface material often look better and sturdier than the reverse.
