Fence details

A fence is a guardrail. Electronic fence is the most advanced perimeter anti-theft alarm system, which consists of an electronic fence host (JS-TD2010) and a front-end detection fence. The electronic fence host generates and receives high-voltage pulse signals, and can generate alarm signals when the front-end detection fence is in the state of touching the net, short circuit, or open circuit, and transmits the intrusion signal to the security alarm center; the front-end detection fence is composed of poles, metal wires and other components A tangible perimeter composed of. Multi-level networking can be achieved through the control keyboard or control software. Basic introduction Chinese name: Fence Foreign name: Fence Wooden fence: an obstacle set for raising various livestock Classification: agricultural fence, industrial fence Composition: fixed fence, movable fence Introduction, history, fence function, classification, iron art Category, Aluminum Alloy, Electronics, Cement, Related Factors, Precautions, Selection Factors, Introduction History From the earliest wooden fences, they were obstacles set up by people to confine various livestock. Today, fences often appear in different forms in our lives and have a very wide range of uses and connotations. The function of fences: Fences for grazing can save manpower, facilitate the rational use of grassland, and improve grassland productivity. Biological fences also have the functions of preventing sandstorms, improving natural conditions, and increasing efficiency. Classified industrial fences (such as factory fences, commercial site fences), agricultural fences (such as field fences, livestock fences), civil fences (such as building roof fences, fence walls, etc.), public facility fences (such as road isolation column) and so on. According to the different materials used, it can be divided into aluminum alloy fence, zinc steel fence, barbed wire fence, electric fence, wood pile fence, biological fence, barbed wire fence, ditch fence, earth wall fence, stone wall fence, Liuba fence, PVC fence , cement fence, etc. Aluminum alloy fences and zinc steel fences are commonly seen in life, and they are also the most widely used. According to the use requirements, it is divided into fixed fence and movable fence. The emerging decorative green fences of various materials are also constantly entering enterprises, various commercial venues and homes.

Characteristics of zinc steel fence: 1. Smooth lines, bright colors, and steady atmosphere. 2. Strong, durable, economical and affordable. High-tech technology is used to produce a permanent coating through a special coating process, which makes the zinc steel fence have super anti-corrosion, moisture resistance, weather resistance and a long-term smooth and flat surface. Easy to clean and requires no maintenance. 3. The style and structure design are diversified to meet the needs of various places. The use of zinc steel fence is widely used in institutions, schools, parks, hospitals, airports, factories, apartments, stations, etc. due to its high strength and durability. Covering almost every corner of our lives. Aluminum alloy fence process design - mold opening - extrusion - straightening - surface treatment - degreasing - washing - aluminum film - washing - drying - powder spraying - forming profiles - blanking - stamping - finished product assembly - transportation - On-site installation-acceptance. The coating is divided into four layers: sprayed layer, chromated layer, sandblasted layer and base layer. Features of Aluminum Alloy Fence This is an emerging category of wrought iron fence. It is made of all-aluminum alloy. It is removable, no welding, and no screws are visible on the surface. The connection is compact and there is no looseness or falling off. Easy to package, transport and install. Fences are easy to process and cost-effective to transport. Aluminum alloy materials can withstand greater pulling force and impact force, and at the same time have better flexibility. The surface is rich in hard aluminum oxide film, and the fence has strong corrosion resistance after surface treatment such as special and anodizing. Aluminum alloy fence uses T5 heat treatment process to greatly enhance the tensile and compressive properties of the fence. It is widely used in offices, schools, parks, hospitals, airports, factories, apartments, stations and other places.

Features of Electronic Electronic Fence Electronic fence is an active intrusion prevention fence that counterattacks intrusion attempts, repels intruders, delays intrusion time, does not threaten human life, and transmits intrusion signals to security department monitoring equipment , to ensure that managers can promptly understand the situation in the alarm area and handle it quickly. The blocking effect of electronic fences is first of all the deterrent function. Warning signs are hung on metal wires, which will cause psychological pressure when you see them. When you touch the fence, you will feel an electric shock, which is enough to deter intruders. Secondly, the electronic fence itself is tangible. The barrier should be installed at an appropriate height and angle to make it difficult to climb; if it is forcibly broken through, the host will send out an alarm signal. The development of electronic fences comes from Europe and the United States, and modern electronic fences originate from Australia. Electronic fences are divided into security electronic fences, animal husbandry electronic fences and zoo-specific electronic fences. It has been widely used in China and has been successfully used in major projects such as the Olympic Games, World Expo, and State Grid, becoming a major product in the perimeter alarm field. In 2008, the national standard for electronic fences was promulgated, and its standard number is: GB/T7946-2008. Electronic fence uses Jinsheng Tongda electronic fence, with its unique performance, is widely used in substations, power plants, government agencies, industrial areas, industrial and mining enterprises, material warehouses, residential areas, villa areas, schools, airports, water plants, aquaculture And livestock farms, key cultural relics sites, military facilities, prisons, detention centers and other places that have walls or require walls. Characteristics of Cement-type Cement Fences Cement fences have the three major advantages of being strong, beautiful, and cheap. Facts have proved that cement fences have won the market with these advantages and are welcomed by users. Of course, it is precisely because of this that cement art fences can be promoted. Development of the equipment industry. 1. Strong. The sturdiness of cement fences is the most important issue for customers. The cement fence uses sand and silicate cement as the main raw materials and is very strong after being formed. Cold-drawn wire is used as the skeleton to enhance the product's resistance and impact resistance. After the fence is installed, the bottoms of the dividing columns and vase columns are firmly fixed on the foundation. On the top, the connecting rods play a role of lateral support. Excluding the stigma of the 1.5m high vase column, the actual height that may be impacted by external forces is only about 1.2m, which greatly enhances the impact resistance of the vase column. 2. Beautiful. The cement fence has beautiful appearance, smooth lines and rich colors. In addition to traditional exterior wall paint and special paint decoration, the painting technology of art fences has also been developed. The application of imitation granite, white marble, imitation bronze and other coating and painting technologies has enriched the decorative appearance of art fences and improved the The decorative taste of cement fences greatly enhances the market competitiveness of cement art fences and significantly improves investors' benefits. Therefore, discerning businessmen are choosing to invest in the cement art fence machine industry. 3. Cheap. Due to the rising price of cast iron, the processing cost of iron art products is getting higher and higher, and the market price remains high. The raw materials of cement art fences are widely available and cheap, and are basically not influenced by upstream suppliers. This is a great advantage for cement art fence manufacturers. Where there are advantages, there will be business opportunities, so if you invest in the cement art fence machine industry now, you will definitely have broad development prospects. 4. No theft value and low maintenance cost. At present, guardrails are mostly made of iron and stainless steel, and a few also use PVC plastic, but there are various disadvantages. Although iron art looks good, it is easy to be stolen and rusted, and needs to be painted and maintained every year. Stainless steel is easy to be damaged and deformed, and is not suitable for outdoor decoration. PVC material products are easy to age and break. Cement art fence solves the various defects of other guardrails. Application of cement fence Cement fence is mainly used in three aspects: exterior wall guardrails, balconies and handrails. Compared with traditional wrought iron, cement products have their own advantages, but we cannot be optimistic that cement fences will replace wrought iron fences just around the corner. This requires the cooperation of the development of the cement fence equipment industry. Only the development pace of the cement fence equipment industry has kept up. Only then can cement fences be used to replace traditional fences.

Relevant factors to note are first of all to pay attention to the analysis during installation. Generally speaking, you need to pay attention to the following points: 1. Do not use this system around flammable and explosive materials. When using it in special circumstances, you should keep a safe distance; 2 . The host cannot be installed in a humid, high or low temperature environment; 3. Do not install it during thunderstorms; 4. The host box is installed at a height that is easy to repair and maintain; 5. Is there strong interference near the installation site of the fence device? Source (such as high-frequency equipment such as transmitting radio stations), if any, indicate in the construction drawing that the signal lines must use prohibited twisted pairs; 6. Once an abnormality occurs, the power supply should be cut off first, and professional installation or maintenance personnel should be notified. Do not dismantle or repair it yourself. 7. Users must have knowledge of electrical safety and electric shock rescue, must undergo professional training, and be familiar with the correct use of the product. The second is the angle problem during the installation process. There are four main installation angles for electronic fences: inward-tilt, outward-tilt, vertical or horizontal installation. As for the specific application method, it is mainly determined according to the specific situation. Here I will briefly introduce to you the angle of installation of lower boundary fence. 1. According to the protection object: when preventing external intrusion, it is recommended to install the outward tilt type; when preventing internal climbing, it is recommended to install the inward tilt type. 2. According to the surrounding environment: it is recommended to install inward or vertical installation near residential areas and schools. It is recommended to install outward in open areas. Horizontal installation can be used when the fence is higher than 2.5 meters. 3. Determine the perimeter fence angle (0°, 22.5°, 45°, 67.5°, 90°, 112.5°, 135°, 157.5°, 180°) and tilt direction (inward-inclined, Cantilevered, vertical or horizontal installation). Selection factors Mesh fence selection 1. Process: galvanized, non-galvanized, steel wire thickness, plastic spraying, plastic dipping; 2. Peach-shaped column fence column spacing; 3. Mesh size; 4. Fence column specifications and wall thickness; 3. Should the column be sprayed or dipped? It is not difficult to find a suitable product by comparing the above fence parameters.
