Float Guardrail / Guardrail for flood

Float Guardrail
Float Guardrail

The floating guardrail is a public safety facility designed for natural disasters such as floods.
Aim:Floating guardrails are aimed at situations where the boundary between the river and the road cannot be identified when the road is flooded. To prevent people from entering the river by mistake when the flood comes
Solution: The guardrail uses the principle of floating to extend the height of the guardrail. The warning ball at the upper end is made of plastic. When the water level is higher than the guardrail, the warning ball will rise to the water level and warn the boundary between the river and the road.
