Metals are prevented from rusting by providing a coating on the surface of the metal to stop the metal from mixing with oxygen and H2O in the air.
Please do not copy this word for word. I am handing this in for a report. Thanks!
Painting will be a good option to prevent rusting.
Tin roofs are typically made from metal sheets manufactured from various materials such as steel or aluminum. These sheets are coated or treated to prevent rusting and provide durability against weather elements. Modern "tin" roofs may also be made from other metals like copper or zinc.
By preventing rusting of iron in bus not being sarcastic at all
The process of coating iron to prevent it from rusting is called galvanization. Galvanization involves applying a protective layer of zinc to the surface of the iron to create a barrier that prevents oxidation and corrosion. This process helps to extend the lifespan of the iron and maintain its appearance.
corrosion (in iron this is called rusting)
any metal covered in zinc. zinc is used to prevent metals from rusting
Some other metals commonly used to prevent rusting include stainless steel (which contains chromium), aluminum, and galvanized steel (which is coated with a layer of zinc). Copper and nickel can also be used for certain applications.

Most of the metals will oxidize, but the only one for which that process is called "rusting" is iron.
You can reduce the air humidity is less oxidizing metals.
Depending on the material that the gates are made of, rust is a potential issue. If they are made from wood rusting won't take place. Additionally, there are many kinds of treatment for metals that can delay or even prevent rusting from happening.
To avoid rusting
Electrolysis can be used to prevent rusting because metals give away electrons and if the metal is wired up to the negative electrode it gains electrons which means it will prevent rusting as it isn't losing electrons.
Coating prevent the iron from contacting air and moisture. So it prevents iron from rusting.
The oily layer prevents water and air from reaching the metal's surface and causing the metal to rust.
