Bridge guardrail is a kind of protective guardrail specially installed on bridges. It can prevent out-of-control vehicles and people walking on the bridge from crossing, going under, and climbing over the bridge, as well as beautify the bridge building.
Bridge guardrails are mainly used in surrounding environments such as bridges, overpasses, rivers, etc. to protect them and not allow vehicles to break through time and space, underground passages, rollover, etc., and also make bridges and rivers more beautiful.
