Replacing steel with plastic
The polymer bridge frame saves multiple processes in the production process compared to traditional metal cable bridge frames; it saves a lot of labor costs and energy consumption during loading, unloading, transportation, construction and installation; during the user's use, because the product itself is maintenance-free + Households, saving users' manpower, material resources and energy. Polymer bridges truly achieve the purpose of “replacing steel with plastic” to save energy and reduce consumption, and contribute to the national environmental protection cause!
Design concept of double-layer hollow structure
According to the principle of mechanical structure, combined with the demand for traditional crystal production, the polymer bridge adopts a double-layer hollow structure, which reduces the weight of the product and improves the bearing capacity of the crystal production, making the product's impact resistance, toughness, strength and other properties better than Crystal made of metal. The double-layer hollow structure can also control the temperature difference between the inside and the outside, automatically form air flow, adjust the temperature inside and outside the crystal production, and play a role in heat dissipation. When the external temperature is too high, it can also block heat and prevent heat from being transmitted to the cable, protecting the cable skin from overheating and causing the occurrence of sticking and leakage.
Insulation without current leakage
Because the polymer bridge is made of high-quality insulation material, it has good and reliable insulation performance. The product is non-conductive and does not need to be grounded, which makes it have excellent performance in safety protection. During the laying of the cable, the mutual inductance of the cable does not produce a magnetic field effect, does not form a current vortex, prevents the cable from heating due to the eddy generated by the current, and saves the current loss caused by overheating.
Corrosion and aging resistance
The polymer bridge adopts special formula and innovative technology, which overcomes the shortcomings of the original steel bridge, such as rust and corrosion. The molecular structure of the raw materials has a natural anticorrosive effect. Combined with different functional additives, the product has better anti-aging quality and is suitable for different climates and other special corrosive environments.
Anti-wear and anti-moth
Because the polymer bridge is made of thermoplastic material, its surface is very smooth, and the frictional force with the cable is very small, and the cable skin will not be scratched due to edges and burrs. The special molecules of the material make the ants, worms, rats and so on have a natural resistance. Its molecular structure is relatively fixed and seamless, making it difficult for microorganisms to adhere and derive, and the product will not rot due to insect frogs.
Flame retardant, smoke suppressing, antistatic
The polymer bridge has the characteristic of high oxygen index, and each index meets the requirements of flame retardant materials. The flame retardant performance reaches GB20286-2006 flame retardant level 1, and the combustion performance reaches GB8624-2012 building materials and products combustion performance level B1, which meets the national building material quality acceptance requirements. The product can withstand a high temperature of 90 degrees in a short time. Even in the event of an accident or fire, due to the good flame retardant physical properties of the polymer, the probability and loss of circuit damage and further deterioration of the accident are effectively reduced.
This product can be designed and developed special antistatic products according to customer requirements to meet the "National Mining Pipe MT-5582-2005" standard.
Beautiful and easy to install
Polymer bridge eve ｜, clean and tidy, smooth lines, changeable colors, strong decorative features. The hollow structure design of the product makes it light in weight, the proportion of raw materials is about 1.5, and the proportion of traditional steel cable trays is about 7.8.

The standard length of this crystal is 4 meters, which greatly improves the installation speed and reduces the waste of accessories resources. It can also be installed after the wiring is completed, which greatly facilitates subsequent capacity expansion and reconstruction, and greatly improves construction. Efficiency and save engineering installation costs.
Durable and long life rabbit jealousy
The special formula used by polymer bridges has the unique properties of anti-oxidation, process innovation, strong weather resistance, no maintenance in application, and the service life is 5-8 times that of traditional cable bridges in general climate and chemical corrosion environment.
Recyclable and environmentally friendly
The polymer bridge production process is simple, and no open flame equipment such as cutting and welding is used during the installation process. Crystal production uses environmentally friendly materials to reduce industrial pollution sources and has no impact on the environment. The bridge can be recycled and processed for recycling, which meets environmental protection requirements and achieves a circular economy.
