What are the reasons for the white rust of hot-dip galvanized screws

1. Causes of white rust on hot-dip galvanized bolts:

1. After the hot-dip galvanized screws are disassembled, they are stacked directly on the ground.

2. Bad weather conditions, such as rainy days, continuous rain, southern sky, etc.

3. In a poorly ventilated and humid environment, the zinc layer on the surface of the hot-dip galvanized screw will react quickly.

2. Preventive measures to prevent white rust of hot-dip galvanized bolts:

1. To avoid accumulation of hot-dip galvanized screws, they should be packed and placed on a shelf.

2. White rust has damaged the appearance of hot-dip galvanized screws. If there are strict requirements on appearance, it can be galvanized again with zinc spray.

3. Place the hot-dip galvanized screws in a ventilated and dry environment. The warehouse environment needs to be improved, and vents and exhaust fans must be added.

4. The screws with white rust can be gently wiped with very rare acetic acid to remove the white rust.
