FRP bridge has many advantages as follows:
Material performance
Light weight: FRP has a relatively small density, and its weight is about 1/4 to 1/5 of that of traditional steel materials, which is easy to carry and install. In some places where the weight of the bridge itself is required, such as the renovation of old buildings, temporary electrical lines, etc., the use of FRP bridge can reduce the load-bearing burden of the building structure.
High strength: Through reasonable structural design and the use of reinforcing materials such as glass fiber, FRP bridge has high mechanical strength and can carry heavier cables and other pipelines to meet the load requirements in different engineering scenarios.
Corrosion resistance: It has excellent corrosion resistance to chemical substances such as acids, alkalis, and salts. When used in corrosive environments such as chemical, marine, and sewage treatment, it will not rust or corrode as easily as metal bridges. It has a long service life and can effectively reduce maintenance costs.
Good insulation performance: Made of insulating materials, it has good electrical insulation performance, which can avoid accidents such as leakage and short circuit caused by contact between the cable and the bridge during transmission, and improve electrical The safety and reliability of the system are particularly suitable for places with high requirements for electrical insulation, such as electronic factories and data centers.
Fireproof performance
Flame retardancy: Flame retardants are added during the production process to make it have good flame retardant properties and not easy to ignite. Even in the event of a fire, it can effectively limit the spread of flames, buy time for personnel evacuation and fire fighting and rescue, and protect the safety of cables and surrounding equipment and facilities. It is suitable for all kinds of places with strict fire protection requirements, such as shopping malls, hospitals, libraries, etc.
Low smoke and non-toxic: It will not produce a lot of thick smoke and toxic and harmful gases during combustion, which reduces the harm to personnel and pollution to the environment during fire, and meets the requirements of fire safety and environmental protection.
Installation and maintenance
Easy installation: The structure is relatively simple and the weight is light. No large hoisting equipment and complex installation tools are required during the installation process, which can greatly shorten the construction period and reduce the difficulty and cost of construction. At the same time, the FRP bridge has various connection methods, such as snap-on, bolt connection, etc., which is convenient for quick assembly and disassembly on site and improves installation efficiency.
Low maintenance cost: Due to its excellent corrosion resistance and aging resistance, it does not require frequent anti-corrosion treatment, repair and replacement during use, reducing the subsequent human, material and financial investment. In addition, its surface is smooth, not easy to accumulate dust, and it is also convenient to clean and maintain.
Appearance design
Beautiful shape: It can be made into bridges of various shapes and colors according to different use environments and customer needs, such as trough type, ladder type, tray type, etc. The appearance is beautiful and generous, coordinated with the surrounding environment, and has a certain decorative effect, which can enhance the overall beauty of the project.
Strong customizability: It can be customized according to the number, specifications, direction and other requirements of the cables in the actual project, such as adjusting the size, height, width, number of layers, etc. of the bridge to meet different wiring needs and improve space utilization.
Other aspects
Environmental protection and health: FRP materials do not contain heavy Metal and radioactive elements are non-toxic, odorless, pollution-free, harmless to the environment and human health, and meet the requirements of modern society for environmental protection and health.
Good weather resistance: It has good weather resistance. Under different climatic conditions, such as high temperature, low temperature, humidity, dryness, etc., it has stable performance and is not prone to aging, deformation, fading and other problems. It can be used outdoors or in harsh environments for a long time.
Electromagnetic compatibility: It can avoid electromagnetic induction heating and high induced voltage caused by metal bridges under high electromagnetic fields, will not cause damage to substation equipment, and can also prevent operation and maintenance personnel from suffering electric shock. It is suitable for substations, communication base stations and other places with high requirements for electromagnetic compatibility.
