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.
