Three-wave collision barriers are commonly used on highways, river embankments, coastal areas, or other high-risk sections. They are connected using three-wave resistance blocks, with dimensions of 300mm*290mm*200mm*4.5mm. The standard post spacing is 2 meters for reinforced models, although some may be as close as 1 meter. Most commonly, the specifications are three-wave panels at 4320mm*506mm*85mm*4.0mm, with posts measuring 130mm*130mm*6.0mm*2540mm.
