Methods for Repair and Maintenance of Guardrail Panels

1. Guardrail manufacturers face the inevitable issue of some vehicles bumping or scraping against the guardrails at both ends of highways. Such guardrails lose their previous anti-skid index and protective effectiveness. Therefore, we have established a regular maintenance schedule. However, it is not feasible to assess the damage through estimation alone; we can use some testing tools for accurate inspection.

2. The difficulty in reflecting the guardrail panels is particularly important in routine inspections, as guardrails that fail to reflect adequately at night cannot provide drivers with proper directional education, thus reflecting checks are subject to strict attention.
