1. Substrate pretreatment

  • Before galvanizing, the steel substrate must first be pickled and chemically treated.

  • This step aims to remove the rust and oxide layer on the surface and provide a good adhesion basis for the subsequent coating.


2. Hot-dip galvanizing process

  • The pretreated substrate is immersed in high-temperature molten zinc liquid.

  • In this process, zinc will form an alloy layer with strong bonding and good adhesion with the surface of the substrate.

  • This process can effectively improve the corrosion resistance of the product and is widely used in construction, home appliances and other fields.


3. Quality control

  • Galvanizing manufacturing requires strict process control to ensure that each process link meets the standard requirements.

  • This includes monitoring and adjustment of key parameters such as zinc liquid temperature, immersion time, cooling rate, etc.


4. Advanced equipment support

  • Modern galvanizing production lines are equipped with professional equipment with high automation and stable precision.

  • Such as continuous pickling lines, hot-dip galvanizing lines, etc., can ensure the consistency and reliability of product quality.


5. Excellent performance

  • After precise manufacturing processes, galvanized steel has excellent corrosion resistance, wear resistance and decorative effects.

  • These performance advantages make it popular in the fields of construction, home appliances, etc., meeting the diverse application needs of customers.


In general, galvanizing manufacturing is a complex and delicate process that requires advanced equipment support and strict quality control. Zibo Jiayue Steel relies on its strong technical strength to provide customers with high-quality galvanized steel solutions.
