First, the use of the environment.
The environment in which the highway sign pole is used is on the highway, so the first thing to consider is to be able to withstand this external environment. The marker pole should be able to resist corrosion, aging, ultraviolet rays, etc., so these factors should be taken into account when choosing materials. Generally speaking, the materials that are more suitable for marking poles are Q235 carbon steel, stainless steel, aluminum alloy, glass fiber reinforced plastic, etc. Among them, carbon steel is cheaper, stainless steel is of better quality, and aluminum alloy and glass fiber reinforced plastic are rare. However, if you use carbon steel as a marker pole, you should pay attention to rust prevention, and you can galvanize the surface and spray plastic to prevent corrosion and rust.
Second, the force.
The main function of the highway marking pole is to play an indicative role, and it needs to withstand the impact force of external vehicles. Therefore, when selecting materials, it is necessary to consider the stress of the material. The shaft of the marker rod and the flange of the connection part need to be calculated for strength, and the material selected must be able to withstand this force. If the road mileage is relatively long, it is better to use two layers of marking poles, which can have a better marking effect.
3. Installation factors.
Highway sign poles need to be installed on the road, so the installation factors need to be considered. The weight of the marker pole should be moderate, not too heavy and not too light. If it is too heavy, it will be inconvenient to install, and if it is too light, it may fall off. In addition, the wind resistance of the marker pole also needs to be considered, especially for some relatively tall marker poles, which must be able to withstand windy weather. Therefore, the material must be able to resist this environment.
Fourth, the cost factor.
The last thing to consider is cost. When choosing materials, you need to take into account the budget of the project and choose materials with high cost performance. There are also great differences in the marking poles of different materials, but even if they are relatively high, as long as they can meet the requirements, they can also be considered. As long as there are no safety hazards due to the material.
In general, the material selection of road marking poles is a comprehensive issue that needs to be taken into account by many factors. When choosing materials, you need to choose according to the actual situation, and you can't blindly follow the trend to choose some materials that are relatively high but the quality is not up to par. After selecting the material, it is also necessary to take protective measures such as anti-corrosion and anti-rust to prolong the service life of the sign pole.
The above is the relevant content about the precautions for the selection of highway sign poles, I hope to help you. If you have any other questions, please feel free to ask.
