Galvanized steel coil is a steel product with a layer of zinc metal coated on the surface of the steel plate. It has many excellent characteristics and wide applications. The following is a detailed introduction to galvanized steel coil, including its characteristics, applications, specifications, production process and price.

  1. Production process of galvanized steel coil
    The production process of galvanized steel coil mainly includes the following steps:
    Steel coil pickling: remove oxides, oil stains and rust on the steel surface to ensure the galvanizing effect.
    Cleaning: rinse the acid, chloride ions and other harmful substances remaining on the surface of the steel coil after pickling.
    Pretreatment: form a protective film on the steel surface to increase the bonding force between the steel coil and the zinc liquid and improve the quality of the coating.
    Baking: make the protective film on the surface of the steel coil completely dry, which is convenient for the subsequent zinc dipping process.
    Zinc dipping: put the baked steel coil into the molten zinc liquid for dipping to form a zinc layer.
    Cooling: make the zinc layer on the surface of the steel coil solidify quickly to ensure the quality of the coating.
    Coil: The galvanized steel coil is rewound and quality inspected.

  3. Characteristics of galvanized steel coil
    Excellent anti-corrosion performance: The zinc layer on the surface of the galvanized steel coil can effectively isolate the steel plate from direct contact with the external environment, prevent the steel plate from being oxidized and corroded, and thus extend the service life of the steel. Even under harsh environmental conditions, such as high humidity and salt, it can maintain good anti-corrosion performance.
    Easy processing: The galvanized steel coil has good processing performance and can be punched, cut, bent, drilled and undergo other processing operations. Its surface is smooth and uniform in texture, reducing the occurrence of burrs and rust after processing, which minimizes the need for post-processing.
    Environmentally friendly and pollution-free: The galvanized steel coil does not produce harmful substances, noise or waste during the production process. At the same time, its surface does not need to be painted, thus avoiding the pollution of the environment by paint.
    High strength: The galvanized steel coil exhibits high strength, hardness, and good bearing capacity, making it suitable for various structures requiring high-strength support.
    Economical: The production cost of galvanized steel coil is low, and the service life is long, which can reduce maintenance and replacement costs. Simultaneously, it is easy to process and install, improving work efficiency and reducing project costs.
