Guardrail bolts can be seen everywhere during our travel time. The isolation devices of urban roads and the guardrail safety facilities of expressways all have special use sites for guardrail bolts. In particular, adjust the guardrail on the road, which is conducive to the deformation of the foundation and beam to eliminate the force of vehicle collision, and protect the safety of driving personnel as much as possible. The device that ensures the function of the guardrail mainly depends on the guardrail bolts. Therefore, when purchasing guardrail bolts, we must find those professional fastener companies that are in the right place.
Recently, when Xiao Bian was travelling in the city, he always came close to see the fixed bolts when he saw the guardrail due to occupational diseases. As a result, he found that many guardrail bolts were missing. Some of them were originally hit by a car and only restored the guardrail to its original position, but they were not fixed with bolts again. In fact, it is very dangerous. A small bolt plays a very important role. When a car crash occurs again, the guardrail is not fixed with bolts, which does not exert force on the collision resistance of the vehicle. In serious cases, the vehicle is easy to run out of control and rush out of the guardrail. So don't underestimate these guardrail bolts. They are very important.
The picture above shows the guardrail and the application environment of guardrail bolts taken by Xiao Bian on the highway. It not only connects the guardrail with the foundation, but also splices the length of the guardrail. Let the guardrails on the whole road form a whole. The head of the guardrail bolt is similar to that of the carriage bolt. It is designed with a round head and has a certain anti-theft function. Because it is used outdoors. If it is a hexagonal design, it is easy for some illegal people to remove it and sell it as waste.
The guardrail is used outdoors, so there is a layer of paint treatment on it, mainly for the convenience of visual observation and anti-corrosion. The guardrail bolts also need surface treatment in order to prevent rust, but the bolts and guardrails are different, and the surface painting process is not suitable for bolt products. Therefore, most guardrail bolts are hot-dip galvanized to solve its anti-corrosion problem.
