Galvanisation is an advanced, cutting-edge process that involves applying a coating of zinc to iron or steel. The primary objective of this procedure is to make the metal highly resistant to rust and other damages. Although manufacturers use different galvanization methods, the most common one is hot-dip galvanising.
A growing body of research evidence shows that galvanised steel has excellent durability and corrosion protection properties due to zinc-iron coating. The zinc acts as a barrier to various corrosive elements and protects the base metal, making the steel high-quality and long-lasting.
Because galvanised steel is highly versatile, many industries, including solar, agriculture, construction, automotive, etc. use it. Today’s article will discuss steel galvanisation and highlight its main advantages. Read on!
What is Steel Galvanisation?
Steel galvanisation is a sophisticated process that involves various steps and stages to achieve high-quality, durable, and corrosion-resistant steel products. The first step requires the manufacturer to clean the steel in a degreasing solution.
Once cleaned, the manufacturing team pickles the steel by lowering it into a vat of hot sulfuric acid. The team uses diluted acid to avoid damages. Next, the manufacturer fluxes the steel in zinc-ammonium chloride and galvanises the metal by immersing it in molten zinc. The final step is to inspect the steel for consistency and proper coating.
Reasons to Choose Galvanised Steel
Numerous industries use galvanised steel because it offers a wide range of advantages, including enhanced protection against corrosive elements and harsh weather conditions. Here are a few benefits of using Galvanised steel. Continue reading!
Low Costs
Unlike other steel types, galvanised steel has lower initial costs because you can use it immediately without requiring additional surface preparation, inspections, coatings, painting, etc. That way, you can save money and streamline your project.
Long-Lasting
Galvanisation is directly proportional to the increased lifespan of the steel material. Research highlights that the galvanisation process makes the steel product last over 50 years in average environments.
Even if the product gets exposed to harsh weather conditions, it will last longer than 20 years. Besides, you don’t need to perform maintenance of the galvanised steel because the finished product is durable and reliable.
Corrosion Resistance
The zinc coating acts as the sacrificial anode and protects the steel from damages. Thanks to the zinc coating, even if the steel gets exposure to environmental elements, it won’t corrode first. It means the zinc coating will corrode first, making the steel last longer and giving you peace of mind.
Rust Resistance
Unlike other steel products and materials, galvanised steel is highly resistant to rust. Remember, the iron elements in the steel are highly vulnerable to rusting, but thanks to the zinc coating, the likelihood of rusting reduces due to the protect buffer between the steel and oxygen or high moisture levels.
In addition, galvanised steel is highly protective. Studies show that other types of coatings cannot protect sharp corners and recesses than zinc coatings. That’s why galvanised steel has increased resistance against various damages, including rust-related problems.
