I believe that you are no stranger to cable trays, and the use of bridges supports our daily lives. What issues should we pay attention to when choosing a bridge? As a cable tray manufacturer that only makes polymer cable trays, let us introduce you to the things you need to pay when buying bridges so that you can better understand them. Confused about buying cable trays? First, when selecting a bridge frame, it is necessary to determine the number of layers of the bridge frame, the width, the type and spacing of the support tracks, and the specific distribution of the cables on each layer of the bridge frame. At the same time, it is necessary to calculate the load required for each layer of cable so that the bridge frame can be used normally under a certain load. Second, we need to conduct further tests in strict accordance with the total uniform load value of the cable. Calculating and calculating the strength of the bridge, it is also necessary to increase the weight of the person during the overhaul of the bridge, and repeatedly check the spacing and type of the bridge to meet the load requirements. The allowable stress of the steel is then calculated to ensure a sufficient protection factor.
    If you purchase cable bridges within the fire protection regulations, you can add flame retardant or flame retardant panels to the pallets of the cable ladder, and materials such as nets form a closed or semi-closed structure. And taking measures such as the bridge and the surface coating of the supporting hangers, the need for fire prevention can be achieved. If you want to use it in a corrosion-resistant environment, you should use a hard, corrosion-resistant material. Or anti-corrosion treatment, anti-corrosion treatment should meet the requirements of engineering environment and durability. If there is a cable line, it requires electromagnetic interference or environmental requirements such as oil, corrosive liquid, and flammable dust. The vented cable tray should not be selected.
    In summary, polymer cable trays are superior to others in terms of corrosion resistance and flame retardancy, so polymer cable trays are the choice of more customers.
