What does a steel bridge look like?

Steel cable tray is a metal structural system used to protect and support wires and cables. It is usually composed of steel plates and sections, and has the advantages of high structural strength, large bearing capacity, and good seismic performance.

The following are some basic requirements for steel cable trays:

1. Structural safety and reliability: The structure of steel cable trays must be able to withstand the weight of its internal wires and cables and external loads to ensure safe and reliable use.  

2. Good seismic performance: Due to the possibility of structural failure of steel cable trays caused by earthquakes, it is required that steel cable trays have good seismic performance to reduce the impact of earthquakes on wires and cables.  

3. Good corrosion resistance: Due to long-term exposure to outdoor environments, steel cable trays are easily affected by corrosion. Therefore, it is required that steel cable trays have good corrosion resistance to improve their service life.  

4. Good electromagnetic shielding performance: In order to protect wires and cables from electromagnetic interference, steel cable trays should have good electromagnetic shielding performance to ensure the stable operation of the power system.  

5. Good aesthetics: The design and appearance of steel cable trays should comply with relevant standards and aesthetic requirements to ensure their good aesthetics during use.  

6. Compliance with relevant standards: The design, manufacturing, and use of steel cable trays should comply with the requirements of relevant standards and specifications to ensure their safety and reliability.  

In summary, steel cable trays are a structural system with wide application value, and their design and manufacturing should follow relevant standards and specifications to ensure good safety and reliability during use.
