The Process :

Galvanization is a process used to protect steel and iron from rust and corrosion by coating them with a layer of zinc. The process is vital for enhancing the longevity and durability of metal products, making them suitable for various industrial and construction applications. Here’s an overview of the galvanization process:

  • Surface Preparation & Cleaning: The metal surface is thoroughly cleaned to remove any dirt, oil, rust, and other impurities. This is typically done through a series of cleaning processes including degreasing, pickling, and rinsing.
  • Fluxing:
    After cleaning, the metal is dipped in a flux solution, usually containing zinc ammonium chloride. This step removes any remaining oxides and helps the zinc adhere to the metal surface by preventing oxidation before the metal enters the galvanizing bath.
  • Galvanizing:
    The cleaned and fluxed metal is then immersed in a bath of molten zinc maintained at a temperature of around 450°C (842°F). The metal stays in the zinc bath until it reaches the same temperature as the molten zinc, ensuring a thorough coating.
  • Cooling and Inspection:
    Once coated, the metal is removed from the zinc bath and allowed to cool. As it cools, the zinc coating hardens and forms a metallurgical bond with the underlying metal. The coated metal is then inspected to ensure it meets the required thickness and quality standards.
  • Post-Treatment (if necessary):
    Depending on the application, the galvanized metal may undergo additional treatments such as passivation or quenching to enhance its corrosion resistance and appearance. Passivation involves applying a chromate coating to the zinc surface to prevent white rust, while quenching involves rapid cooling in water or air.

Benefits of Galvanization

  • Corrosion Resistance: The zinc coating provides a protective barrier that prevents moisture and oxygen from reaching the underlying metal, thus significantly reducing the risk of rust and corrosion.
  • Durability: Galvanized coatings can withstand harsh environmental conditions, making them ideal for outdoor and industrial applications.
  • Cost-Effectiveness: Despite the initial investment, galvanization is cost-effective over the long term due to reduced maintenance and replacement costs.
  • Adherence to Standards: The process adheres to stringent British and American standards, ensuring high-quality, reliable products.
    By incorporating this advanced galvanization process, Bonn Metals Construction Industries can offer superior galvanized products that meet rigorous quality standards and cater to a wide range of customer needs at competitive prices.
