Proper protection of galvanized sheet coils can extend their service life and ensure they maintain good performance under different environmental conditions. Here are some suggestions on how to properly protect galvanized sheet coils:

1. When handling, transporting and storing, we should be careful to avoid contact with hard objects and avoid mechanical damage.

2. Avoid contact with corrosive substances such as acids, alkalis or salts.

3. Galvanized sheet coils should be stored under dry storage conditions to prevent moisture and moisture from causing corrosion. Store in a well-ventilated warehouse or storage area.

4. Avoid stacking.

5. If there is damage to the surface of the galvanized coil, such as scratches or peeling, it should be repaired in time to prevent corrosion from spreading in the damaged area.

6. Galvanized sheet coils may accumulate dust, dirt or other contaminants during use. Clean the coating regularly to maintain its appearance and performance.

7. When galvanized coils come into contact with different metals, electrolytic effects may occur, leading to corrosion. When in contact with other metals, we should take steps to prevent electrolytic effects, such as using insulating materials or appropriate coatings.

In a normal working environment, the thickness of the galvanized layer of hot-dip galvanized coils reaches more than 50um and can be used safely for 30 years. This is based on the anode protection principle of the iron matrix. This method of hot-dip galvanizing allows the pure zinc layer to form a dense protective film in the atmospheric environment to prevent zinc corrosion. But if we encounter a humid environment, we must apply asphalt or seal the trench to isolate the direct contact between the medium and the zinc layer, so as to prevent corrosion and perforation of the galvanized layer.
