Wire-reinforced glass is also known as shatterproof glass. It is made by heating ordinary flat glass to a red-hot and softened state, and then pressing preheated iron wire or wire mesh into the middle of the glass. Its characteristics are excellent fire resistance, capable of blocking flames, not cracking when burning at high temperatures, and not causing injury from fragments when broken. In addition, it has anti-theft performance. Even if the glass is cut, it can still be blocked by wire mesh. It is mainly used for roof skylights and balcony Windows.
Wire-reinforced glass is also known as shatter-resistant glass and steel wire glass. In the calendering production process, it is a special kind of glass formed by pressing the wire mesh into a semi-liquid glass strip. The advantage is that it is stronger than ordinary glass. When the glass is impacted or subjected to sudden temperature changes, it can break but not shatter, and crack but not disperse, preventing small angular fragments from flying out and injuring people. Even if a fire spreads and the wire-reinforced glass shatters due to heat, it can still remain in a fixed state, playing a role in isolating the fire. Therefore, it is also called fire-resistant glass. The drawback is that during the production process, the wire mesh is prone to oxidation due to high-temperature radiation, and the glass surface may develop a yellow color like "rust spots" and bubbles. Wired glass is often used in skylights, ceiling covers, and doors and Windows that are prone to vibration.
Even if wire-reinforced glass is broken, the wire or mesh can support the fragments and it is very difficult for them to fall off and shatter. Even when the flame breaks through, it can block the invasion of the flame and fire powder, and has the effect of preventing the spread and spread of the fire through the opening.
According to Article 64 of the Japanese Building Standards Act, regulations have been made for fireproof doors. The opening of the outer wall must prevent the spread and spread of flames. Combining wire-reinforced glass with the frame of a type B fireproof door can be used as a Type B fireproof material.
Ordinary glass is very easy to break, so thieves can sneak in to carry out illegal activities, but wired glass is not. Even if the glass breaks, there is still the metal wire mesh at work, so thieves cannot steal easily. The anti-theft property of wire-reinforced glass brings people a sense of security psychologically.
Because there are metal wires or meshes inside the wire-reinforced glass body, the integrity of the wire-reinforced glass is greatly improved. When causing damage, it avoids the overall collapse, thus having a certain fireproof effect and safety effect. The disadvantage of wire-reinforced glass is its poor transparency. Due to the presence of wire mesh inside, it has a certain interference with the visual effect. Secondly, the exposed metal wire at the edge of the glass is prone to corrosion. The safety of wire-reinforced and mesh-reinforced glass is reflected in the fact that it remains intact even when damaged. The glass fragments will not fall apart under the pull of the wire, reducing the harm to the human body. It can be used in skylights, roofs, indoor partitions and other places where debris is likely to cause injury. In addition, since the wire mesh glass is not easy to penetrate, it also has a certain anti-theft effect when used for door and window glass. Laminated glass can also be used as a secondary fireproof material for doors and Windows. Ordinary glass is prone to cracking and falling due to heat when a fire breaks out, causing air circulation and the spread of the fire. Although the glass with wire mesh may shatter in a fire, it will not fall or Pierce through due to the support of the metal wire or mesh. It can maintain its integrity to a considerable extent, prevent the flow of air, and has a good blocking effect on the spread of the fire. Wire-reinforced and meshed glass are also suitable for seismic protection applications, such as buildings with high seismic protection requirements and factories with industrial vibrations. Wire-reinforced and mesh-reinforced glass have improved the brittle nature of flat glass, which is prone to breakage. It is a kind of architectural glass with low cost and wide application.
