(1) According to building regulations, wire glass is commonly used as a safety measure to prevent the spread of fire. First, when the door glass is cut, the cut portion becomes more fragile. The strength of this slit area is roughly half that of regular glass, making it more prone to thermal cracking under stress or temperature changes. This can lead to unexpected breakage, which is a major concern in safety-critical applications. Second, the wire mesh embedded in the glass is typically treated to resist corrosion and rust. However, the cut portion—where the glass is sliced—remains untreated. If exposed to moisture over time, this area can begin to rust. In severe cases, the rusting process may cause expansion, leading to cracks along the edge of the glass. These cracks weaken the structure, increasing the risk of failure and contributing to thermal breakage. It's important to note that while wire glass offers certain advantages in fire resistance, improper cutting or handling can compromise its integrity. Therefore, it's recommended to use professional installation and proper maintenance to ensure long-term performance and safety.
