There are different ways or methods to prevent rust formation on metals (see corrosion prevention). The selection of the most appropriate methods depends on many factors like: type of metal, type of environmental exposure, operating conditions...

One of the most common and used method is to paint the metal with an appropriate coating that prevent the contact between the metal and the environment.

The selection of the material that can resist corrosion and rust is another way to prevent the formation of rust (see material selection for corrosion control & prevention): a typical example is the use of Stainless Steel material that are resistant to corrosion in most environment.
