The Benefits of Galvanizing: Why More Industries are Turning to Galvanizers

More industries are turning to galvanizers nationally and internationally since, over time, it has become evident that it is the most cost-effective way of protecting steel over long periods. Steel that has been treated with hot dip galvanization with an average thickness of 85 microns, the thickness of a sheet of photo-copier paper, can protect the metal for up to 100 years. Alternative methods of corrosion prevention are proving to have levels of protection for only a fraction of that time.

Globally recognised galvanizers, Armco Superlite explain the benefits of galvanization and why more industries are demanding the treatment before using steel in the manufacture of their products.

4 Reasons why Galvanizers recommend Galvanization  

Hot dip galvanizing is the process by which raw, cleaned steel products are immersed into a bath of molten zinc to obtain a coating that is metallurgically bonded to it. The finished product protects against corrosion (or rust) over a long period. There are many benefits to processing the metal in this way and, in the initial stages of planning and preparation for a project, these are often misunderstood or overlooked.

  1. Initial Economic Benefits: When preparing a costing analysis before the commencement of any project involving large quantities of steel, factor in galvanizing as part of the process. The material is prepared and galvanized offsite. Alternative methods may need rustproofing during or post-construction, onsite, leading to additional labour costs and delays in construction time.
  2. Durability and Lowest Long-Term Costs: Some alternatives may appear cheaper initially. However, galvanization lifespans are reliable and predictable and have been historically proven to last longer. Even if dented or scratched, the coating protects the metal, reducing the chances of erosion.
  3. Less Maintenance: Rust and rustproofing is a laborious and time-consuming task post-construction. Consequential losses due to business closure during this process may be exorbitant. This process may have to be repeated every few years with alternative products. Inflation-related labour and material costs also need to be factored in. Galvanized steel does not need these intermittent treatments. Once coated, it may last between 50 to 100 years with very little maintenance in between.
  4. Toughest Coating for Complete Protection: A galvanized coating is bonded to the metal. It offers outstanding resistance to mechanical damage in transport, construction and service. The bonding covers every part of the treated material, even recesses, bolt and screw threads, sharp corners and inaccessible areas. Once the construction is completed, there is no further protection required.
