Aluminum insect screen will also rust under certain conditions, and it has the ability to corrode in the medium containing acid, alkali and salt---that is, corrosion resistance. However, the size of its anti-corrosion ability varies with the chemical composition of the material itself, the mutual state, the use conditions and the type of environmental media. Therefore, the aluminum insect screen is not resistant to corrosion and rust in any environment. Once the film is continuously damaged for some reason, the oxygen atoms in the air or liquid will continue to infiltrate or the iron atoms in the metal will continue to separate. When it leaves, loose iron oxide is formed, and the metal surface is continuously corroded.

Recommendations to ensure that the metal surface is permanently bright and does not get rusted:
1. The surface of decorative stainless steel must be cleaned and scrubbed frequently to remove attachments and eliminate external factors that cause modification.
2. 316 stainless steel should be used in seaside areas, which can resist seawater corrosion.
3. The chemical composition of some stainless steel pipes on the market cannot meet the corresponding national standards and cannot meet the 304 material requirements. Therefore, it will also cause rust, which requires users to carefully select
