When making punching construction fences, waterproofing needs to be done in advance, so it is necessary to apply a layer of waterproofing on the surface of the fence, which not only has an aesthetic effect, but also increases the service life of the fence. The surface treatment process includes spraying, dipping, and painting. The fence on the construction site is basically treated with spraying, which has a beautiful appearance. The commonly used colors are mainly yellow and white, and some are made into red, white, or yellow black, with obvious colors and a safety warning effect.
