What is the name of the iron fence on the construction site?

The official name of the subway fence is: colored board enclosure.

For the engineering color steel enclosure structure, the pre-installation work should be done when the enclosure structure is installed. For example, some green trees need to be transplanted to other places, so that the municipal construction enclosure will be stable after installation and will not fall down easily to avoid being blown down by strong winds. The installation of municipal construction enclosure must be carried out on the premise of not affecting pedestrian safety and traffic. When installing the construction enclosure, the construction site should be completely isolated from the outside world, so as to prevent irrelevant personnel from entering the construction area and avoid danger. After installing the construction enclosure, please arrange special personnel to patrol outside the installation of the hydraulic enclosure to maintain the order of inconvenient roads caused by the installation of the enclosure. Finally, it is emphasized that it is forbidden to place sundries, dirt and other things that you don't want to close near the municipal construction enclosure, so as to keep the municipal construction enclosure clean and beautiful and not affect the appearance of the city.
