When discussing coated steels, two commonly encountered terms are Zintec and Galvanised. Both materials describe steel which has undergone a coating process to increase corrosion resistance; however, there are distinct distinctions between them that make each suitable for specific applications.
This content outline will compare Zintec and Galvanised steel materials, such as their definitions, manufacturing processes, characteristics, properties, applications and key distinctions. By studying their differences closely we can gain a comprehensive understanding of both materials for use across various industries.
Definition of Zintec
Zintec steel sheets are specifically engineered to offer enhanced corrosion resistance and superior surface characteristics, trademarked under Tata Steel’s brand. Zintec can be found across various industries where corrosion protection and surface quality play an essential role, including automotive, construction and electrical sectors.
“Zintec” is an acronym combining zinc and electrolytic. This material’s manufacturing process involves electroplating a thin coating of zinc onto steel sheets as a barrier against corrosion; providing protection for their core.
Zintec boasts several advantages over galvanized steel in comparison. It boasts an extremely smooth and uniform surface, making it perfect for painting or other surface finishes, as well as good formability that enables it to be quickly formed into various components and structures. Furthermore, its weldability enables seamless joining with other metal parts.
Zintec is known for its corrosion resistance, paintability and formability – making it suitable for applications requiring high-quality finishes.
Definition of Galvanised
Galvanised or galvanized steel or iron refers to material that has been coated with an protective zinc layer through an electroplating or bath dipping process, known as galvanization. Galvanization involves immersing these products in an immersion bath of molten zinc or electroplating zinc onto them through electroplating processes.
Galvanizing is designed to protect metal bases against corrosion. Zinc coating acts as a sacrificial layer, meaning that its corrosion preferentially attacks steel or iron beneath, protecting it from rust and other forms of corrosion.
Furthermore, this protective barrier acts as an additional shield between your substrate and its environment preventing moisture and other corrosive agents from coming directly into contact with its substrate.
Galvanised steel or iron has a distinctive silver-gray hue due to the presence of zinc coating, with various thicknesses available ranging from an “electrogalvanized” thin coat all the way through “hot-dip galvanization.”
Galvanised materials have an array of industries and applications. Galvanised steel is often employed in construction as it offers increased durability and corrosion resistance for roofing, fencing, structural components and outdoor installations; additionally it may be employed in automotive parts, electrical conduits, agricultural equipment as well as any other industries where corrosion protection is key.
Galvanising refers to the process of coating steel or iron with zinc in order to provide corrosion protection, extending its lifespan and increasing its durability.

Steps involved in galvanising steel
Galvanizing steel involves several steps.
Here are the usual ones:
Prep Work: Prior to galvanized coating application, steel must first be cleaned of dirt, oil, grease or rust on its surface. This step is critical to ensure optimal adhesion of galvanized coating.
Acid Cleaning: After galvanizing has taken place, steel must be submerged in an acid bath – typically made up of hydrochloric or sulfuric acid – in order to remove any remaining mill scale or oxides on its surface. This process, known as pickling, helps create an even and reactive surface ready for galvanizing.
Fluxing: After acid cleaning, steel must be rinsed to remove any residual acidity and then immersed in a flux solution to help remove any remaining oxides, prevent further corrosion of its surface, and facilitate zinc flow during galvanizing processes.
Galvanizing Bath: Once prepared steel has been galvanized, it must be immersed into a molten zinc bath that typically maintains an ambient temperature between 450degC (850degF) and 475degC (865degF), consisting of zinc alloys to improve coating performance and to provide uniform coverage of coating coverage. The steel must remain completely submerged to allow even coverage throughout its length.
Formation of Zinc Coating: When steel is immersed into a bath of molten zinc, an industrial reaction known as hot-dip galvanizing occurs. Iron reacts with the zinc in the bath to form zinc-iron alloy layers on its surface – their thickness being determined by immersion time in the bath.
Quenching: Once steel has been extracted from its galvanizing bath, it must be quenched quickly by immersing it in water or an appropriate combination of chemicals to rapidly cool it and solidify the zinc coating without producing excess zinc oxide formation.
Inspection and Quality Control: Galvanized steel must be visually inspected, as well as put through various quality control tests, in order to meet its required standards. Such tests include thickness measurement, adhesion testing, visual examination for coating uniformity, salt spray corrosion testing and salt spray corrosion resistance testing.
Finishing and Post-Treatment (Optional): Depending on its application and desired aesthetic finish, galvanized steel may undergo additional processes after galvanizing to increase corrosion resistance or create aesthetic finishes such as passivation, chromate conversion coatings or painting for aesthetic purposes or enhanced corrosion protection. These processes could include passivation, chromate conversion coating or painting to provide further corrosion resistance or achieve desired aesthetic finishes.
Note that variations may exist depending on both the galvanizing facility and steel being galvanized, as well as on any special processes used, such as centrifugal galvanizing or continuous galvanizing for specific applications or types of steel.
