The highway features of completely enclosed unidirectional driving and a variety of transport engineering facilities. These characteristics ensure the high speed of the vehicle driving, so that the highway has more advantages of the various means of modern transportation, more efficient, safe, convenient and comfortable. Here is the brief introduction of the main structure and function of guardrail system of highway. With the increase of vehicle speed, safety becomes an important factor affecting traffic. In order to maximize the protection of vehicles and personal safety, on both sides of the highway and the middle isolation zone are equipped with highway\u00a0guardrail beams\u00a0and anti-collision steel posts. A resistance block,off-set block, is connected between the guardrail beam and the steel post(also called, the connection spacer).
