Xiaobian reminds you: 1. When building traffic guardrails, we must pay attention to the problem of light. Only when our lighting equipment is normal can we carry out construction. In order to ensure the safety of traffic fence construction, a certain distance must be kept from dangerous equipment during construction to avoid harm. People working with us must understand some technical specifications of this project.
