The amount of wind that the outdoor LED screen sheet metal cabinet can withstand mainly depends on its wind resistance level and structural design and other factors.
The following is a summary and analysis based on the information provided in the reference article:
1. Definition of Wind Resistance Rating:
- The wind resistance rating of an outdoor display is a rating standard that measures its ability to withstand wind. Generally speaking, the wind resistance rating refers to the stability and endurance level of the outdoor display at a specific wind speed.
2. Classification of wind resistance grades:
- At present, the wind resistance level of domestic outdoor display screens is usually divided into several levels, such as 7, 8, and 9. The higher the wind resistance level, the stronger the wind resistance of the display.
3. Relationship between wind power and wind resistance level:
- There is no direct quantitative relationship between the wind resistance rating and the specific wind force (e.g., typhoon level), but in general, a higher wind resistance rating means that it can withstand stronger winds.
4. Design & Installation:
- The design and spacing of the back cover of the LED display will affect its wind resistance. A thin back cover or too much spacing of the studs can cause the display to be damaged by the wind.
- The structural design of LED display needs to take into account its strength, rigidity, stability, and reliability in the work, while reducing its own weight as much as possible.
5. Regional Differences:
- Different regions have different requirements for wind resistance. Inland cities may have a lower demand for wind resistance, while coastal areas require a higher wind resistance rating to cope with severe weather such as typhoons.
6. Special Requirements:
- In some extreme weather conditions, such as LED pole screens, wind resistance needs may reach level 12 in inland cities and 16 or higher in coastal areas.
7. Specific figures:
- The reference article does not directly give the data on how much wind (such as how many km/h) the outdoor LED screen sheet metal cabinet can withstand, because this data is affected by various factors such as display design, materials, and installation conditions.
To sum up, the wind strength that the outdoor LED screen sheet metal cabinet can withstand is a relative concept, which needs to be comprehensively evaluated according to the specific wind resistance level, structural design, installation conditions and the climate characteristics of the region.
When purchasing and installing outdoor LED screens, these factors should be fully considered, and the display and installation scheme suitable for the local climate characteristics should be selected.
