Nowadays, most of the bridge guardrails used in parks and bridges are made of zinc steel, which is basically exposed to the air. Prolonged exposure to the sun, wind, and shower can cause corrosion of guardrails. Because bridge guardrails are tools used to prevent pedestrians or vehicles from crossing them in emergency situations, it is highly likely that their durability will not be guaranteed in the long run.

As a zinc steel river guardrail, the first priority is to withstand all weather conditions in the environment, as well as withstand the intrusion of violence, and even to some extent, to be as hard and reliable as the wall. At the same time, no matter how much impact force it is subjected to, it should also be reduced in pressure and slowed down. So when using zinc steel river guardrails for maintenance, it is necessary to apply a layer of anti-corrosion paint to the guardrails after construction, which can block the oxidation reaction between air and metal. And it is necessary to take care of the zinc steel river guardrail every once in a while, which can delay the aging of the guardrail and also beautify the environment.
