quality Cable Tray & Stainless Steel Cable Tray factory

Many people have heard of and even used hot-dip galvanized cable trays, which are used to protect circuits, cables, instrument lines, and other circuits from disturbance and damage. Usually, the equipment is installed on walls or ceilings, with a simple structure, flexible equipment, and no pressure when installed. Today, let's summarize the importance of stainless steel cable trays. As we all know, the normal use of power lines directly affects our lives. Regardless of which industry we are in, once there is a problem with the power lines, whether it is in factories, residential areas, or other buildings, it will bring inconvenience, especially in the manufacturing industry, such as machinery factories, food factories, electrical factories, shoe factories, hardware factories, clothing factories, cosmetics factories, dairy products factories, etc. These local power lines are mostly used, and if not handled properly, they may easily lead to hidden dangers. The anti rust function of stainless steel cable trays is essentially possible, but it also needs to be classified in detail. As stainless steel cable trays are made of materials such as 201, 304, and 316L, if you want to use them for a long time indoors, 304 stainless steel cable trays can be used. However, if the application site is highly corrosive, 316L stainless steel cable trays will be more suitable, and they can all be used for more than 70 years with sufficient hardness to meet the application requirements. In order to avoid these unnecessary phenomena, 304 stainless steel cable trays should be used for protection in areas where wires, cables, and instrument signal lines are densely distributed. Moreover, nowadays, hot-dip galvanized cable tray manufacturers also use stainless steel cable trays in many places, such as some parking lots, factories, residential areas, and teaching buildings.

The types of external anti-corrosion coatings on cable trays mainly include hot-dip galvanizing, nickel plating, cold galvanizing, powder electrostatic spraying, and other methods. According to the data from the hot-dip galvanizing cable tray manufacturer, the service life of the hot-dip galvanizing process is not less than 40 years, and it is suitable for outdoor severely corrosive environments with high costs;   The service life of galvanized nickel process is not less than 30 years, and it is also suitable for outdoor severe corrosive environments with high cost; The lifespan of the cold galvanizing process is not less than 12 years, suitable for outdoor environments with light corrosion, and the cost is average; The service life of powder electrostatic spraying technology is not less than 12 years, suitable for indoor room temperature and dry environment, and the price is average.

Hot dip galvanized cable tray manufacturers' products are widely used for cable laying connecting various production workshops   The hot-dip galvanizing process can be regarded as the "soul" of this type of bridge. The traditional hot-dip galvanizing operation relies heavily on manual experience, making it difficult to accurately control parameters such as zinc solution temperature and immersion time, resulting in uneven quality of the bridge structure. Nowadays, good hot-dip galvanized bridge manufacturers have introduced advanced automated temperature control systems.   In the zinc pool, there are high-precision temperature sensors densely distributed, which act as sharp "nerve endings" to monitor the temperature of the zinc solution in real time. Once there is a slight fluctuation in temperature, the automation system will quickly start and maintain the temperature of the zinc solution within the immersion range through intelligent heating or cooling devices, ensuring that each section of the bridge can be uniformly coated with a zinc layer. The control of immersion time no longer relies on manual timing, but on advanced time sensing devices. Hot dip zinc bridge manufacturers set the immersion time precisely based on the material, thickness, and other parameters of the bridge, achieving high standardization and refinement of the process.   For hot-dip galvanized bridge manufacturers, the selection of raw materials is like the cornerstone of a high-rise building. They abandoned the common low-quality steel and instead collaborated with well-known steel companies to select steel with controlled carbon content and low impurity content. These steels undergo multiple rounds of rigorous testing before being put into production. Not only do we need to test its conventional performance indicators such as hardness and toughness, but we also use advanced spectral analyzers to deeply analyze the chemical composition of the steel, ensuring that each batch of steel meets production standards.   During the production process, hot-dip galvanized bridge manufacturers also perform special pre-treatment on the surface of the steel. Through multiple processes such as acid washing and degreasing, impurities such as rust and oil stains on the surface of the steel are removed, creating an "adhesion foundation" for the hot-dip galvanizing process. This allows the zinc layer to tightly bond with the steel, greatly improving the corrosion resistance of the bridge.   The application scenarios of hot-dip galvanized cable trays are very wide, and their importance is particularly prominent in the chemical industry. Chemical production is often accompanied by highly corrosive gases and liquids, and ordinary cable trays are like a "fragile defense line" in such an environment, which can suffer severe corrosion in a short period of time, endangering cable safety.

In modern architecture, fire-resistant cable trays are important safety facilities that undertake the critical task of ensuring the safe operation of the power system. This special cable laying system not only has the functions of traditional cable trays, but also has excellent fire resistance performance, becoming an indispensable part of the building safety system. The core value of fire-resistant cable trays lies in their unique fire-resistant construction. It uses galvanized steel plate as the substrate, and the surface has undergone special fireproof treatment, which can withstand high temperatures above 1000 ℃. In the event of a fire, fire-resistant cable trays can effectively block the spread of flames, saving valuable time for personnel evacuation and firefighting rescue. The fireproof material filled inside can expand at high temperatures to form a dense protective layer, ensuring that the cable maintains normal operation in the event of a fire. In construction engineering, the application scenarios of fire-resistant cable trays are very extensive. From high-rise office buildings to underground parking lots, from hospitals to data centers, its presence can be seen in any area that requires Z-point fire prevention. Especially in densely populated areas and important equipment rooms, fire-resistant cable trays play an irreplaceable role. It can not only protect cables from fire threats, but also prevent fires from spreading through cable channels, minimizing fire losses. With the continuous improvement of building safety standards, the technology of fire-resistant cable trays is also constantly innovating. The application of the new nano fireproof coating has further improved the fire resistance of the bridge frame; The integration of intelligent monitoring system enables the fireproof bridge to have real-time monitoring and warning functions. These technological advancements have made fire-resistant cable trays play an increasingly important role in the field of building safety.   The existence of fire-resistant cable trays reflects the high importance placed on safety in modern architecture. It is not only a physical barrier, but also a concrete embodiment of the concept of building safety. In the future development of architecture, fire-resistant cable trays will continue to play the role of safety guardians, providing reliable protection for people's lives and property safety.

1) Straight steel cable trays exceeding 30m in length and large-span aluminum alloy or fiberglass cable trays exceeding 15m in length should not have expansion joints. Compensation devices should be installed at the deformation joints of the cable trays crossing buildings.   2) The bending radius at the turning point of the cable tray shall not be less than the allowable bending radius of the cables inside the tray.   3) When there is no requirement in the design, the spacing between the supports for horizontal installation of cable trays is 1-5-3m, and the spacing between the supports for vertical installation is greater than 2m.   4) The bridge and bracket are securely fastened with bridge connecting plates and bolts, and the nuts are located on the outer side of the bridge.
