The issue of reflection on guardrail beam is also important

The reflection problem of guardrail beam is also a particularly important issue in daily inspection. Guardrail beam that have lost their reflection effect cannot provide drivers with correct direction guidance at night, so reflection inspection is also important to pay attention to!

The waveform guardrail beam installed on both sides of the highway are inevitably scratched and collided by some vehicles, resulting in the loss of their previous collision resistance and protective effect. Therefore, we need to stop regular maintenance on them. But sometimes guardrail beam is not possible to visually inspect whether it is damaged, and we can use some professional testing tools to stop checking for defects!
