Understanding the manufacturing process of aluminum zinc coated coils

Aluminum zinc coated coils are a common metal coating product mainly used for corrosion prevention and enhancing material weather resistance. The following is the production process of aluminum zinc coated coils:

1. Steel coil preparation: Firstly, the selected high-quality steel coil is cleaned and surface treated to ensure a clean surface and remove any impurities and oxides.

2. Zinc aluminum coating preparation: Prepare the liquid zinc aluminum alloy solution, usually by heating the aluminum and zinc alloy solution to a liquid state.

3. Continuous galvanizing: The surface treated steel coil is coated with a layer of aluminum zinc alloy solution through a coating line, and then the alloy coating is cured on the surface of the steel coil through heating and cooling processes.

4. Adhesive baking: The steel coil coated with aluminum zinc alloy is sent into the baking furnace to bake and cure the alloy coating, ensuring its adhesion is firm.

5. Cooling and coiling: After baking, the steel coil is cooled by a cooling device, then cut into the required length and rolled into coils.

6. Packaging and quality inspection: Finally, pack the aluminum zinc coated coils and conduct quality inspections to ensure that the coating is uniform, firmly attached, and meets relevant standard requirements.

7. This is the general production process for aluminum zinc coated coils, and the actual production process may vary depending on different manufacturers and technologies.
