In simple words, rust can be defined as a type of iron oxide, which forms due to the combination of iron with oxygen. The orange-brown discoloration, which is called rust, will gradually cause metals to corrode. Rust will affect iron and all of its alloys including steel.

As most people are commonly aware, rust results in the expansion of metals, which will in turn put increased pressure on the entire structure. During the same time, you will be able to see that the metal has become brittle and weak. Fortunately, there are several simple but effective ways to prevent rusting and they are discussed below.


Galvanizing is one of the most common methods used to prevent rust. This is achieved by electroplating or galvanizing the corroded object. During the process of galvanizing, the steel or iron object will be coated with a small zinc layer. This will prevent water and oxygen from reaching the object, but Zinc also serves as a sacrificing agent during the process.

Corten Or Weathering Steel

Corten or weathering steel contains approximately 21 percent of nickel, copper, phosphorus, chromium, and other alloying elements. As a result, the alloy creates a rust patina, which acts as a protective layer by considerably reducing the rate of corrosion.

Stainless Steel

Stainless steel is actually an alloy and the percent of chromium in stainless steel is estimated to be around 11 percent. This allows the alloy to form a protective film, which will shield the object against the formation of rust. The protective firm will automatically re-form if it gets damaged. If you want to further enhance corrosion resistance, then it is best to add nickel.

Here are some other common techniques or processes that will prevent metals from rusting.

  • Bluing
  • Proper and regular maintenance
  • Powder coating
  • Organic coating
  • FOZZ
