TransportationGuardrails are more aesthetically pleasing and practical. Installation is also more convenient, suitable for various municipal buildings and roads. City guardrails are one of the most popular road separation barriers both domestically and internationally. They are mainly used for outdoor buffer zones, municipal engineering buffer zones, and park guardrails. They isolate and protect parks, lawns, zoos, lakes, roads, and residential areas during municipal construction; as well as for the protection and decoration of hotels, large shopping malls, and markets.
