Stainless steel and galvanized steel They can look similar and be confused But they are totally different in terms of resistance, weight and composition. Today we want to mention the differences between galvanized steel and stainless steel. 

Previously in our blog we have mentioned everything from the different applications of steel in everyday life to curiosities and information about galvanized steel.

Also, if you want to know the different uses of steel sheet, we also explain it to you.


What are the differences between galvanized steel and stainless steel?

Both galvanized steel and stainless steel are used in corrosive environments. Although they resemble each other, as we have mentioned before, they are totally different.

Below we will explain some of their differences:



On the one hand, the production of Galvanised steel is the result of Dipping ordinary steel into a pool of molten zinc, what is known as hot dip. It can also be done through the method of electro-immersion, where steel is immersed in an electrolyte solution containing zinc, using electrolysis to create the coating. 

Moreover, The production of stainless steel is produced by mixing steel with chromium in different quantities. As the mixture cools, it hardens, at which point the compound is treated with an acid to remove any impurities that may remain attached to the surface.

Steel preparation



El stainless steel It is an iron alloy with approximately 10% chromium and other elements; Meanwhile he Galvanised steel has a zinc coating layer on the surface to avoid oxidation.



El Galvanized steel is relatively weaker than stainless steel, as it contains only an outer layer of anti-corrosion coating that wears off over time. For its part, stainless steel is resistant to corrosion due to a molecular effect called passivation, in which chromium oxide molecules immediately restore any scratch or cut to the metal. 



El Galvanised steel, due to its weaker resistance and cheaper price, is used for Lower budget projects than stainless steel. In addition, galvanizing is very common in the production of air conditioning, ventilation, heating equipment, and metal roofing in construction.

To this we must add that products made with galvanized steel are capable of resisting corrosion, resisting inclement weather and are stronger and lighter than many other metals.

For its part, and because the stainless steel It is more expensive, although also more durable, it is used for big budget projects that require a lot of work heavy or thick components. Therefore, it is perfect for the construction of skyscrapers, bridges, sculptures and monuments, automobiles, railways, airplanes and a series of other high-end products or public works.


environmental factor

One of the main benefits of stainless steel is that it can be recycled as many times as you want, something that does not happen with galvanized steel. Galvanized steel can be recycled, but to do so it requires being galvanized again with zinc so that it can provide the same performance and resistance as before.

In conclusion, steel is in continuous progress, growth and evolution, as new alloys and coatings emerge.

As you have seen, both types of steel, stainless and galvanized, have very interesting characteristics. Did you know all its characteristics?
