Yes, the surface of the aluminum guardrail will oxidize. Although the aluminum guardrail will undergo surface treatment during the production process, such as anodizing, to enhance its corrosion resistance and durability, oxidation may still occur when exposed to the external environment for a long time, especially in a humid environment.
In addition, if the surface of the aluminum guardrail is accidentally contaminated with acids, alkalis and other chemicals, it may also lead to oxidation and corrosion. In order to prevent oxidation, the aluminum guardrail can be cleaned and maintained regularly, and the chemical substances on the surface can be washed with water in time. If the surface of the aluminum guardrail has been oxidized, you can consider using professional care products or homemade protective coatings to treat it to extend its service life.
