Galvanized Steel Production Process

The galvanized steel production process includes two main stages: surface preparation and cleaning, and zinc coating on the steel. To ensure high quality and reliable corrosion resistance of galvanized steel, both stages are crucial and require accuracy and high technical standards.

  1. Surface Preparation and Cleaning

This is the first and most important step in the galvanized steel production process. The goal of this stage is to clean the steel surface and remove rust, grease, and other contaminants to prepare for the next zinc coating process.

The steps involved are as follows:

a. Contaminant removal: The steel is passed through pickling tanks to remove dirt, grease, and other impurities from the surface. The pickling process is quick and efficient, ensuring that the zinc coating adheres firmly to the steel surface.

b. Sandblasting (if needed): For steel with heavy rust or requiring polishing, sandblasting is performed to clean the steel and prepare the surface for galvanizing.

c. Acid treatment: In some cases, acid may be used to clean the steel surface in detail and remove difficult contaminants.

  1. Zinc Coating on the Steel

After the steel surface is thoroughly cleaned, the zinc coating process will be carried out. Zinc coating is the process of applying a layer of molten zinc, which provides a strong zinc coating firmly adhered to the steel surface through either electroplating or hot-dip coating methods.

The steps involved are as follows:

a. Electroplating: The steel is passed through a zinc solution tank. The use of electric current promotes a chemical reaction between the steel and zinc, resulting in a firm zinc coating on the steel surface. This method is common for galvanizing small and complex details.

b. Hot-dip coating: The steel is passed through a molten zinc bath at a high temperature, where the zinc melts and forms a firm zinc coating on the steel surface. This method is often used to galvanise large sheets or sheets of special sizes and shapes.

After the zinc coating stage is completed, galvanized steel is carefully inspected to ensure that the quality and technical properties meet the standards. Galvanized steel that has undergone this production process will have excellent corrosion resistance and durability, effectively serving the purpose of construction and industry.

Considerations When Using Galvanized Steel

There are several considerations to ensure its corrosion resistance and good performance during use when using galvanised steel. The following are important points to consider when using galvanized steel:

  1. Proper storage and transportation:

During transportation and storage, galvanized steel should be handled with care to avoid breakage, scratches, or surface damage. In particular, avoid contact with chemicals and strong mechanical impacts that can damage the zinc coating and reduce the corrosion resistance of the steel.

  1. Product quality check:

Before use, thoroughly inspect the galvanized steel to ensure its technical properties and durability. Check the surface of the steel for any defects, scratches, or abnormalities. If any issues are found, promptly inform the supplier or manufacturer to receive support and address the issue.
