City fences are more aesthetically pleasing and practical. Installation is also more convenient, suitable for various municipal buildings and roads. City fences are one of the most popular road separation barriers both domestically and internationally. Mainly used in outdoor separators, municipal engineering separators, and park fences. They separate and protect parks, lawns, zoos, lakes, roads, and residential areas during municipal construction; as well as providing protection and decoration for hotels, large shopping malls, and marketplaces.
