Two Methods For Producing Galvanized Steel Sheets

Steel is a metal used widely around the globe. From high-end, towering skyscrapers to HVAC units, in construction and manufacturing, steel remains a low-cost and highly favored metal. The high strength of the material combines with its excellent strength, formability and low cost, make it popular. Yet, the metal does suffer from a low tolerance to corrosive elements. To overcome this, fabricators cover the metal in a protective coating producing galvanized steel sheets capable of withstanding the forces causing corrosion.

Corrosion vs. Galvanized Steel

No one doubts bare steel corrodes. The onset of rust can have serious consequences. For a sculptor, it destroys the aesthetic appeal of the metal. For architects, construction companies, and manufacturers, the harm is much graver. Rusting steel threatens the integrity and stability of a structure and the ability of a component to function appropriately. This increases the cost of maintenance and replacements. Galvanization prevents this occurring. By using galvanized steel sheets, fabricators can decrease the potential of this serious problem.

Methods of Galvanization

Steel galvanization involves the application of zinc to the metal. A fabricator can employ any of several methods. The two below are the most common.

* Hot-dip Galvanizing: This is the most common means through which fabricators apply zinc to steel. The steel passes through a hot, liquefied zinc bath (ca 860 °F). The result is triple protection from corrosive elements through

* Barrier
* Cathodic
* Patina

* Electrogalvanizing:  This method does not employ a molten zinc bath. Replacing this is a system of electrolyte solution and electrical current. The result is:

* Consistent coating
* Precise thickness

* Galvanized Steel Sheets

Bare steel is not very effective against corrosion. To improve this metal’s ability to endure, fabricators will produce galvanized steel. Sheets of steel prepared in this way are an inexpensive and effective way of reducing the negative aesthetic and economic effects rust and corrosion can have on steel applications.
