Wired Glass,Anti-theft,Fireproof Wire Glass

Wired glass is also called shatterproof glass and steel wire glass. It is made by heating ordinary flat glass to a red-hot softened state, and then pressing preheated iron wire or wire mesh into the middle of the glass. Its characteristics are excellent fire resistance, it can block flames, it will not explode when burned at high temperatures, and it will not cause fragments to hurt people when broken. In addition, it also has anti-theft properties, and the barbed wire will stop the glass from being cut. Mainly used for roof skylights and balcony windows.
Wired glass uses skylights to light the roof; balconies and anti-theft business halls. Features: safety; anti-theft; fire resistance.
Basic introduction Wired glass is also called shatterproof glass and steel wire glass. During the calendering production process, a wire mesh is pressed into a semi-liquid glass ribbon to form a special glass. The advantage is that it is stronger than ordinary glass. When the glass is subjected to impact or drastic changes in temperature, it will break without missing or cracking, preventing small angular fragments from flying out and injuring people. For example, when a fire spreads and wired glass explodes due to heat, It can still maintain a fixed state and play the role of isolating fire, so it is also called fireproof glass. The disadvantage is that during the production process, the wire mesh is easily oxidized by high-temperature radiation, and yellow and bubbles like “rust spots” may appear on the glass surface. Wired glass is often used in skylights, ceilings, and doors and windows that are susceptible to vibration. Features: Even if fire-resistant wired glass is broken, the wires or nets can hold the fragments, making it difficult to chip and break. Even when the flame breaks through, it can block the intrusion of flame and fire powder, and has the effect of preventing the spread and spread of burning from the opening.

Wired glass complies with Article 64 of the Japanese Building Standards Act, which stipulates fire doors. The outer wall opening must prevent the spread of flames. Using wired glass combined with the frame of Class B fire doors can be used as Class B fireproof materials. Safety wired glass prevents flying debris. Even if the glass is broken by external pressure such as earthquakes, storms, impacts, etc., the fragments are difficult to fly, so compared with ordinary glass, it is less likely to cause fragments to fly and injure people. Anti-theft Regular glass is easily broken, so thieves can sneak in and carry out illegal activities, but wired glass is not. Even if the glass is broken, the metal wire network is still in effect, so thieves cannot easily steal it. The anti-theft properties of wired glass bring people a psychological sense of security. Since there are metal wires or meshes inside the wired glass, the integrity of the wired glass is greatly improved. It avoids overall collapse when destroyed, so it has a certain fire prevention effect and safety effect. The disadvantage of wired glass is that it has poor perspective because there is a wire mesh inside, which interferes with the visual effect. Secondly, the exposed metal wires on the edge of the glass are easily corroded. The safety of wired and meshed glass is reflected in the fact that it maintains its integrity when damaged. The glass fragments will remain in place under the pull of the wire, reducing harm to the human body. It can be used on skylights, roofs, indoor partitions and other places where debris can easily cause injury. In addition, since wire mesh glass is not easy to penetrate, it also has a certain anti-theft effect when used in door and window glass. Laminated glass can also be used as secondary door and window fireproof materials. Ordinary glass is easily cracked and shattered by heat during a fire, causing air flow and the spread of fire. Although the glass with wire mesh will explode in a fire, it will not collapse and penetrate due to the support of metal wire or mesh. It can maintain its integrity to a certain extent, prevent the flow of air, and have a good resistance to the spread of fire. effect. Wired and mesh glass are also suitable for earthquake-proof occasions, such as buildings with high requirements for earthquake protection and factories with industrial vibrations. Wired and mesh glass improves the brittle nature of flat glass and is a low-cost, widely used architectural glass. Purpose (1) According to the provisions of the Building Law, wired glass is used to prevent fire. First, when ordinary glass is cut, the cut part is easily damaged. The strength of the cutout is about half that of wired glass, so it is more likely to cause thermal breakage than wired glass.

Wired glass door (2) The wire mesh surface of wired glass has been specially treated and is generally not easy to rust. The cut parts are left untreated, so they may rust when exposed to water. If it is severe, the cut part may crack due to volume expansion, reducing the strength of the edge. This is what causes thermal cracking. The production process involves a roll of wire mesh that is unrolled by a mesh supply device and sent to the molten glass. The molten glass passes through the upper and lower calendering rollers to form wired glass. The shape of the wire mesh grid in wired glass is generally square or hexagonal, and the glass surface can be patterned or smooth. The thickness of wired glass is generally 6-16mm (excluding the thickness of intermediate wires). Safety glass can be used on building ceilings and other occasions
