One of the notable advantages of Cast Aluminum Doors is their exceptional corrosion resistance. Aluminum, in its natural state, forms a protective oxide layer when exposed to air, which acts as a barrier against further oxidation. This inherent property is enhanced through the casting process, where additional protective coatings can be applied to the surface of the aluminum. These coatings not only augment the door's resistance to rust and corrosion but also provide a spectrum of color options and finishes, allowing for a bespoke aesthetic that complements any architectural style.
