Vacuum glass is a type of insulating glass that is sealed with a vacuum between the two layers of glass. It is known for its high insulation value and can be used in a variety of applications, including windows and doors in residential and commercial buildings. One of the key challenges when transporting and storing vacuum glass is ensuring that it is not damaged or scratched. This is especially important if the vacuum glass is being used in a high-visibility area, as scratches or other imperfections can be easily noticed. One solution to this problem is to use a protective glass shelf, such as the “harp glass shelf” mentioned in the description. This shelf is designed to hold the vacuum glass securely and prevent it from being scratched or damaged during transport and storage. To further protect the vacuum glass, it is also important to pay attention to the material of the screw sleeves that come into contact with the glass. Using a material that is soft and gentle on the glass can help to prevent scratching and damage. Overall, proper protection of vacuum glass during transportation and storage is essential to ensure that it arrives at its destination in perfect condition. By using protective measures such as a glass shelf and paying attention to the materials used in contact with the glass, it is possible to keep vacuum glass safe and undamaged during transport and storage.
