1. Performance characteristics

  1. Appearance: The galvanized steel coil has a bright and smooth surface, is free of rust spots and defects, and is beautiful and elegant.

  2. Corrosion resistance: The galvanized layer can provide effective protection, giving the galvanized coil a long service life.

  3. Mechanical properties: Galvanized coils have high strength and hardness and are suitable for various mechanical requirements.

  4. Processability: galvanized steel coils are easy to cut, stamp, bend, and weld, and are suitable for various processing techniques.


2. Application fields

  1. Construction field: Galvanized sheet coils are widely used in building roofs, walls, insulation layers, ventilation ducts, and other fields, and have good protective and decorative effects.

  2.  Automobile field: Galvanized sheet coils can be used for body, chassis, parts, etc. in automobile manufacturing, providing good corrosion resistance and strength.

  3. Home appliance field: galvanized steel coils are suitable for refrigeration equipment, washing machines, electric heaters, etc. in home appliance manufacturing, and have good rust resistance and aesthetics.

  4. Manufacturing field: Galvanized sheet coils can be used to manufacture various metal products, such as tanks, boxes, pipes, etc., with high plasticity and strength.


3. Detailed explanation of the production process

  1. Raw material selection: The raw material of galvanized coils is usually low-carbon steel, which has good castability and weldability.

  2. Plate processing: The raw materials are processed through pickling, cold rolling, and annealing to obtain plates with high flatness and dimensional accuracy.

  3. Surface treatment: The plate undergoes oil removal, rust removal, and surface pretreatment to ensure the adhesion and uniformity of the coating.

  4. Galvanizing process: The plate uses a hot-dip galvanizing process to evenly cover the zinc coating on the surface of the steel plate to form a good protective layer.
