Why Is Galvanizing Important?

Galvanization is the process of putting a protective zinc coating to steel or iron in order to avoid early rust and corrosion. Because of its unique properties, proponents of galvanized steel, who may use it to construct or repair steel structures, gain from cheaper maintenance and repair expenses.

Steel will rust because of atmospheric conditions over time if it is not protected. The degree of rusting will be determined by the product’s surroundings. Rust is an iron oxide (usually a red oxide) produced by the reduction and oxidation reaction of iron and oxygen in the presence of water or atmospheric moisture.

There are protective techniques available, such as painting or plastic coating, but they have disadvantages. When broken, components of the steel rust and the protective coating peels away, rendering various forms of protection ineffective and untrustworthy (always needing continued maintenance).

Hot-dip galvanization is one of the finest ways to maintain steel products against corrosion. Under the Hot-dip galvanization process, the material’s whole surface is dipped in molten zinc and coated entirely.

Zinc corrodes relatively slowly, giving it a longer lifespan while protecting the base metal. Cathodic protection occurs as a result of the alloying of zinc and iron. This assures that rust does not affect small sections of steel that may be exposed due to damage. Small damaged areas, unlike organic coatings, do not require touch-ups. As long as the zinc layer is there, the cathodic protection will continue.
Take extra precautions if your project comes in contact between any galvanized material and copper or brass. This is especially true in a wet or humid atmosphere, where zinc corrosion may occur quickly. Water that runs off a copper or brass surface may contain enough dissolved copper to induce fast corrosion. If this is the case in your circumstance, make sure to prevent that water flows from the galvanized material to the brass or copper components.


The major benefits of utilizing Galvanized are as follows:

  • Less expensive than stainless steel.
  • Less maintenance/Lowest long-term cost.
  • Life expectancy is high.
  • Coating life and performance are consistent.
  • Excellent resilience to mechanical harm.
  • Small portions of steel exposed due to damage are protected.
  • No other coating can offer the same level of protection.
  • There is no lost time in surface preparation, painting, or inspection.
