Install pvc road mesh fence

The specifications for the strength of pvc road mesh fence in the standard are determined after loading test or collision strength test. Various parameters are specified in detail. The strength standard of pvc is to find a balance between test strength and performance. , The role of pvc is not only to prevent the car from getting into the bottom of the truck, but more importantly, it acts as a buffer. In the standard, there is a sentence: "The rear lower protection should be able to absorb collision energy to mitigate the impact." Therefore, it is not right to blindly emphasize the strength of PVC, just like a car crashing into a solid wall. Instead, the walls can cause heavy casualties. In the standard, the requirement for pvc is to allow cracking and deformation, but not to fall off.

From the perspective of passive safety, the purpose of installing PVC on trucks is to protect the safety of the people in the car; from the perspective of active safety, the driver of the car must control the speed, pay attention to observation, and ensure a safe following distance, because as long as the speed exceeds Soon, even if the truck is equipped with pvc, it will not prevent the car from causing heavy casualties after a rear-end collision.
